History

+

+ +Pcb is a handy tool for laying out printed circuit +boards. +It was first written for an Atari ST in 1990 and ported to UNIX and +X11 in 1994. +I never had the intention to create another professional layout system, +but to write a tool which supports people like you who do some +home-developing of hardware. For this reason it has no auto-router nor +auto-placement code. + + +

+The second release 1.2 included menus for the first time. This made +PCB easier to use and thus a more important tool. + + +

+Release 1.3 introduced undo for highly-destructive commands, +more straightforward action handling and scalable fonts. Layer-groups +were introduced to group signal-layers together. + + +

+Release 1.4 provided support for add-on device drivers. +Two layers (the solder and the component side) +were added to support SMD elements. The handling of libraries +was also improved in 1.4.1. Support for additional devices like +GERBER plotters started in 1.4.4. The undo feature was expanded +and the redo-feature added in 1.4.5. + + +

+Release 1.5 provides support for rats-nest generation from simple net +lists. It also allows for automatic clearances around pins that pierce +a polygon. A variety of other enhancments including a Gerber RS274X +driver and NC drill file generation have also been added. +harry eaton (haceaton@aplcomm.jhuapl.edu) +was responsible for most of the changes found in this release. + + +

+Release 1.6 provides automatic screen updates of changed regions. +This should elliminate most of the need for the redraw (r) key. +Also some changes to what order items under the cursor are selected +were made for better consistancy - it is no longer possible to +accidentally move a line or line point that is completely obscured +by a polygon laying over top of it. Larger objects on the upper +most layers can be selected ahead of smaller objects on lower layers. +These changes make operations more intuitive. A new mode of line +creation was added that creates two line on 45 degree angles +with a single click. The actual outline of the prospective line(s) are +now shown during line creation. An arc creation mode was added. +Drawn arcs are quarter circles and can be useful for high frequency +controlled impedance lines. (You can have eighth circle arc if the +source is compiled with -DARC45, but be aware that the ends of such +arcs can never intersect a grid point). Two new flags for pins and +vias were created - one indicates that the pin or via is purely a +drill hole and has no copper annulus. You can only toggle this flag +for vias - for elements, it must be an integral part of the element +definition. The other flag controls whether the pad will be round +or octagonal. There is also now a feature for converting the contents +of a buffer into an element. Vias become the pins (or mounting holes), +lines and arcs on the solder layer become silkscreen, and lines on the +component layer become the pads. Action commands entered via the colon +command entry are no longer proceeded with "a ", just type the command +directly. Several bugs have also been fixed. New +ones were probably introduced since extensive changes were made. +harry eaton was responsible for these changes. + + +

+Release 1.6.1 adds the ability to make groups of action commands bound to +a single X11 event to be undone by a single undo. Also a simple design rule +checker was added - it checks for minimum spacing and overlap rules. Plus +many fixes for bugs introduced with the many changes of 1.6 +harry is responsible for these changes too. + + +

Introduction

+

+Each layout consists of several, mostly independent, objects. This chapter +gives an overview of the object types and their relationship to each other. +For a complete description of how to use Pcb, refer to +section Getting Started. +The layout is generated on-screen on a grid that has its origin in the +upper left corner of the screen. +The x coordinate increases to the right, y increases down to the bottom. +All distances and sizes in Pcb are measured in mils (0.001 inch). +One unit on the display grid is one mil in distance on the board. +The sections in this chapter are sorted by the +order of appearance of the objects within a layout file. + + + +

+ +

+ + + + +

Symbols

+

+The top object is the layout itself. It uses a set of symbols +that resides at the first logical level. Each symbol is uniquely identified +by a seven bit ASCII code. All layout objects share the same set of +symbols. These symbols are used to form text objects on the silkscreen +and copper layers. Undefined symbols are drawn as filled rectangles. + + +

+Every font file is preprocessed by a user-defined command when it is loaded. +For details see `fontCommand', section Non-Standard X11 Application Resources. + + +

+ + + +

Vias

+

+Vias are identical to the pins used by elements except that they can be added +or removed individually. +The purpose of vias is to provide connections between different layers. +Don't use vias for adding elements to the layout, even if that seems +easier than creating a new element. +Vias are useful for defining arbitrary drill points such as +those used for mounting a board. +You can assign a name to a via even though you probably won't ever want to. +Vias reside at the first logical level; therefore, each +via exists on all layers. (i.e. +blind vias are not supported) + + +

+ + + + +

Elements

+

+Elements represent the components on a board. +Elements are loaded from ASCII coded files in a +similar manner to the layout file itself. +They are composed of lines and arcs on the silk-screen +layer (used to define the package outline) , pins +(or pads for SMD) and three labels that define the +description, the element's layout-name (which also +appears on the silk- screen layer) and its value. +Element pins are contained on the first logical level +and so reside on all layers. +A mark is used to position the element with +respect to the cursor cross-hair during pasting. +SMD elements use pads instead of pins. +Pads are handled similarly to lines on a layer but they must be oriented +either vertically or horizontally. +Pads can have either rounded or square ends. +All parts of an element are treated as one unit. +It is not possible to delete a single pin or break +an element into pieces on the layout. +You can resize separate pieces of an element, +but doing so is usually a bad idea. + + +

+Elements are supported by several special layers: silk, pins/pads and +far-side. The silk layer shows the package outline and +also holds legend text and element names. The pins/pads layer is used to toggle +whether the element's pins and pads are displayed. The far-side layer controls visibility +of objects (silkscreen and pads) that are on the far (i.e. not currently viewed) side +of the board. + + +

+Every element file is preprocessed by a user-defined command when the file is read. +For details see `elementCommand', section Non-Standard X11 Application Resources. m4, the default +value of `elementCommand', allows you to create libraries for +package definitions that are shared by all elements. +The element libraries distributed with Pcb expect m4 or an +equivalent to be the elementCommand. + + +

+Pcb can create a list of +all connections from one (or all) elements to the others or a list of +unconnected pins. +It can also verify the layout connections against a netlist file. +The element's `layout-name' is the name used to identify an element +in a netlist file. +The pin numbering for an element is defined by unique strings assigned to +each pin. In addition to the "pin number" string, each pin has a "name" +which describes its function. Previously element pin number was established +by the order of appearance of the pin definitions in the layout or element +file. Since the "number" strings for each pin are a new feature, if they are +absent then the numbering is again established by the order of pin appearance +in the file. +In other words, the first pin appearing in the file is pin one, the +next pin is pin two and so on. +Usually the names assigned to pins are simply numbers, but they don't +have to be. It is only necessary that the "number" string for the pin +matches exactly the "number" string in the netlist file. +Be aware that a few of the library parts may still be incorrectly +implemented regarding pin-numbering. All of the DIL (Dual- +Inline-Pins) parts are correct and most of the others are too, +but you should verify the pin numbering +of any non-DIL part (use the Report Menu to see what Pcb thinks a pin's +number is) before using the rats nest feature with a library part. Hopefully sometime +soon someone will volunteer to cross-check all of the element libraries and make +fixes available as necessary. +Pcb can also check a layout to see that it meets minimum spacing +and overlap rules. + + +

+You can make your own quick-and-dirty element definitions graphically now. +Simply draw vias for the pins +and lines and arcs on a solder layer for the silkscreen +outline. You should name each via with the pin number. +If you want to create a SMD device, draw lines for the pads on a +component side layer (You must draw these in pin number order since lines can't +be named). They must be +either horizontal or vertical or they will not be recognized as pads. Once +you are happy with the geometry, select everything that is to become part of +the element, then choose "cut to buffer" from the menu. Now select "convert +buffer to element" from the menu. Viola'! Afterwards you can make pin one +square (or pads) if you like, and give the element its various names. Note that the +element mark corresponds to the cut position when everything was put into the +buffer. If the vias are not named, then the pin numbering will correspond to the +order in which the vias were placed. + + +

+ + + +

Layers

+

+Every layout consists of several layers that can be used independently +or treated as a group. +Layer groups can be used to logically separate (and color-code) +different traces (e.g. power and signal); however, all +layers within a group reside on the same physical +copper layer of a board, so using different layers within the same +group won't provide electrical separation where they touch or overlap. +For details, see `layerGroups', section Non-Standard X11 Application Resources. +Each layer is drawn in a color defined in the resource file (for +details see `layerColor', section Non-Standard X11 Application Resources) and identified by a name +that you can change. +Layers are really just containers for line, polygon, and text objects. The +component and solder layers contain SMD elements as well, but the +file structure doesn't reflect that fact directly. Each layer group +represents a physical layer on the printed circuit board. If you want to make +a four layer board, you'll need to have four layer groups. +Connections between layer groups are established only through element pins and vias. +The relationship between a specific layer and the board itself is configureable from +the `Edit layer groups' option in the `Objects' menu. +The layer groups corresponding to the physical layers component-side +and solder-side are always defined, and you must map at least one +logical layer to each. +Of course, you are not obligated to put tracks on either of them. +SMD-elements always reside on either the component-side or the solder-side +layer group. +You can swap which side of the board you are viewing by pressing +<Key>Tab. +You can decide which layer group will be the solder side and which will be +the component side. +The layers groups just have a name or number associated with them - where +they are sandwiched in the board is left to the manufacturing processes. + + +

+ + + +

Lines

+

+Lines are used to draw tracks on the pc board. +When in the line mode, each <Btn1> +press establishes one end of a line. +Once the second point is defined, the line is drawn +and a new line started where the first one ended. +You can abondon the new starting point in favor +of another by pressing Ctrl<Btn1>. +The undo function (<Key>u) will take you back +point by point if you use it while in the line mode. +New lines can be restricted to 45 degree angles if desired. You can toggle this +restriction on and off while creating lines by pressing <Key>. (that is the +period key). If the 45 degree restriction is turned on, then the <Key>/ +can be used to cylce through three different modes of 45 degree line creation. +One mode just creates a single line forced to the nearest 45 degree vector. The next +mode creates two lines from the start to end points such that the first line leaves the +start point at a 90 degree vector, and the second line enters the end point on a 45 +degree vector. The next mode creates two lines such that the first line leaves the +start point on a 45 degree vector and arrives at the end point on a 90 degree vector. +You can temporarily swap between the last two modes by holding the shift key down. +It is simple to edit a line type object by breaking it into pieces (insert point mode), +moving an end point (or the whole line) (<Btn2Down><drag><Btn2Up>), +or changing the layer it resides on (<Key>m moves the line under the pointer +to the active layer). +In the case when two line segments meet at exactly the same +point you can delete the intermediate point, otherwise the delete mode removes an entire line. +Feel free to experiment +since Pcb will allow you to undo anything that materially affects your work. +If you switch active layers in the midst of placing lines a via will automatically be +placed, when necessary, in order to continue the connection. + + +

+ + + +

Arcs

+

+With version 1.6 it is possible to draw copper arcs. The arcs are restricted to +be quarter circles. This means they always bend a right angle. They are very similar +to lines otherwise. They are created on the current layer and have the same thickness +that new lines will have. The various clicks for creating lines work pretty much the +same way for creating arcs. The start point for the arc is at the first <Btn1> +position. In order to make the arc curve in the direction desired, drag the mouse along +the tangent line from the starting position towards the end position. If the grid is +too coarse, it may not be possible to distinguish whether you've moved over then up, +or up then over, so if you can't seem to make the arc go the direction you want, you +should decrease the grid spacing. Alternatively you could drawn the wrong arc, then +rotate and move it where you want. Like the line tool, after an arc is drawn a new +starting point is established at the end point. Whenever a start point is established +by either the line or arc tools it will be retained if you switch directly between the +tools (e.g. <Key>F2 for Lines, <Key>F8 for Arcs. Of course connection +searches, undo and all the other features you'd expect work with arcs now. + + +

+ + + +

Polygons

+

+Sometimes it's useful to fill large areas with solid copper. +The way to do this is with polygons. +Polygons can be created in either the polygon mode or the rectangle mode. +In the polygon mode, you'll have to define each corner of the polygon +with a mouse click (<Btn1>). When the last point is clicked +exactly on top of the starting point, the polygon is finished. +Since this can be hard to do, the Shift<Key>p will enter the +final point for you, closing the polygon. +If the 45 degree angle restriction is turned on +and you try to close the polygon when it is not possible, you'll get a +warning instead. If you haven't finished entering a polygon, but want to +undo one (or more) of the points that you've already defined, use the +undo command (<Key>u). +With the rectangle tool, defining +the two opposite corners is sufficient, but of course the resulting +polygon is a rectangle. +Like lines, a polygon can by edited by deleting, inserting and moving the points +that define it. +Pcb is capable of handling complex polygons, but +using a number of simpler ones improves performance of the connection tracing code. + + +

+A new feature in version 1.5 of Pcb automatically creates clearance +regions around pins and vias that pierce a polygon. This means that they +aren't electrically connected to the polygon unless you add "thermals" +to cross the clearance region. +Thermals can be added and removed by selecting the thermal mode and clicking +<Btn1> on the pin or via. +Remember that this only creates connections to the polygon on the active layer. +The great advantage to this new polygon behavior is that simple or complex ground +and/or power planes can be easily made with polygons and seen on the screen. +If you don't want this auto-clearance behavior, or you load a layout created by +an earlier version of Pcb, the old behavior +(shorts to all piercing pins and vias) is available. A `ChangeSize' +operation (<Key>s) toggles a polygon between the new and old polygon/pin +behavior. + + +

+ + + + +

Text

+

+Text objects should be used to label a layout or to put additional +information on the board, but not to identify elements because elements +have their own labels. +Text is always horizontal when first created, but the +rotate mode can align it along 0, 90, 180 and 270 degree angles. +Text can be moved from any layer to the silk-screen layer with a +command in the `selection menu'. +Text that is moved to the silk-screen layer will appear on the +solder-side silk-screen if it originating on a solder-side layer. +Otherwise moving it to the silk-screen layer will put it on the +component-side silk-screen. +To move text back to a copper layer from +the silk-screen, use the `MoveToCurrentLayer' (<Key>m) command. +Text on the far side of the board will automatically appear mirror-imaged. + + +

+TEXT OBJECTS ON A COPPER LAYER CREATE COPPER LINES BUT THEY ARE NOT SCANNED FOR +CONNECTIONS OR TESTED FOR CREATING SHORTS VS. THE NETLIST. NEITHER ARE TEXT OBJECTS TESTED AGAINST ANY DESIGN RULES. + + +

+ + + +

Getting Started

+

+The goal of this chapter is to give you enough information to learn how +Pcb works and how to develop your layouts to make the best use of Pcb's +features. All event translations (i.e. the buttons and keys you +press) refer to the default application resource file shipped with Pcb. +There is probably no need to change them unless your window +manager uses some of the button events itself; however, if you want +to customize the behavior of Pcb then changing the resource file +is usually the best way to do it. + + +

+Get yourself a printout of this chapter and User Commands, if you +haven't already done so, and follow the examples. +An example layout may be found in `example/68HC11'. +An example illustrating some version 1.5 features is found in +`example/LED' along with its corresponding netlist file `example/LED.NET'. + + +

+Start Pcb (the actual command will use all lower-case letters) +without any additional options. +If you get the error message: + + + +

+    can't find default font-symbol-file 'default_font'
+
+ +

+then the font searchpath or filename in the application resource +file is wrong. Be sure that your m4 program supports searchpaths. +If not, get GNU m4. +For other messages, see section Troubleshooting. +Another quick-start is provided by pcbtest.sh in the `src' +directory. + + + +

+ + + +

The Application Window

+

+The main window consists of five areas: +the menu at the top, the control panel in the upper left corner, the mode buttons +located below the control panel, the drawing area to the right of these, and the +status line at the bottom of the window. + + + +

+ +

+ + + + + +

The Status-line and Input-field

+

+The status-line is located at the bottom edge of the main window. +During normal operation the status information is visible there. +When a selected menu operation requires an additional button click, the +status-line is replaced by a message telling you to position the cursor +and click. +When a text input is required, the status-line is replaced by the +Input-field which has a prompt for the typed input. + + +

+The status-line shows, from left to right, the side of the board that you +are viewing (<Key>Tab changes this), if an absolute +(abs) or relative (rel) grid is used, if new lines are restricted to 45 degrees, +which type of 45 degree line mode is active, whether rubberband move and +rotate mode is on (R), the current grid values, and the zoom factor. +This information is followed by the line-width, via-size +and drilling hole in mil, text scaling, the active buffer number and the +name of the layout. An asterisk appearing at the left edge indicates the +layout has been modified since the last save. +Note that the name of the layout is not the same +thing as the filename of the layout. + + +

+The input-field pops up (temporarily replacing the status-line) whenever user input +is required. Two keys are bound to the input field: <Key>Escape +aborts the input, <Key>Return finishes it. + + +

+The present cursor position is displayed in the upper right corner of the window. +Normally this position is an absolute coordinate, but with +version 1.5 of Pcb you can anchor a marker at +the current cursor location by pressing Ctrl<Key>m then the +display will read both the absolute cursor position as well as the difference +between it and the marker. Pressing Ctrl<Key>m again turns the marker off. + + +

+ + + + + + +

The Control Panel

+

+The control panel, located at the left side of the window, is used to turn on +and off the display of layer groups and to select the active drawing layer. +If a layer hasn't been named, the label "(unknown)" is used as the defualt. + + +

+The upper control box is used to switch layers on and off. Click +<Btn1Down> on one or more of them. Each click toggles the setting. +The currently active layer can't be switched off. +The layout is refreshed when the pointer reenters the drawing area. This +prevents excessive redrawing when the visibility of several layers is changed. +When the layers are grouped, clicking on these fields will toggle +the visibility of all layers in the same group. This is a good idea because +layers in the same group reside on the same physical layer of +the actual board. +Use the `Edit layer groups' option in the `Objects' menu to +change the layer groupings. +Grouping layers is only useful for helping you to color-code +signals in your layout. Note that grouping layers actually reduces the number +of different physical layers available for your board, thus to make an eight +layer board, you cannot group any layers. + + +

+far side turns on and off the visibility of elements +(including SMD pads) on the opposite +board side, as well as silk screening on that side. It does not automatically +hide the x-ray view of the other copper layers, these must be turned off +separately if desired. Use the tab key to view the entire board from the other +side. To see a view of what the back side of the board will actually look like, +make the solder layer the active layer then press tab until the status +line says "solder" on the right, then turn off the visibility of all other layers +except pins/pads, vias, and silk. + + +

+The lower control menu, named active, is used to change the active +drawing layer. <Btn1Down> pops up a menu to select a one. +Each entry is labeled with the layer's name and drawn in its color. +The new drawing layer is automatically made visible. +Try changing the active layer's name to ABC by selecting +`set name of layer' from the `File' menu. +Changing the active layer also is available with <Key>1..8. + + +

+ + + + +

The Mode Selectors

+

+The mode selector buttons reside below the control panel. +They are used to select the operation mode of Pcb. A mode can be +thought of as a tool that gets used when <Btn1> is pressed. +Each mode causes the cursor to take on a unique shape that identifies the tool. +The buttons themselves are icons that illustrate their function. +The drawing modes can also be selected from the keyboard: + +

+    <Key>Escape   reset mode
+    <Key>F1       via-mode
+    <Key>F2       line-mode
+    <Key>F3       pastebuffer-mode
+    <Key>F4       rectangle-mode
+    <Key>F5       text-mode
+    <Key>F6       polygon-mode
+    <Key>Insert   insert-point-mode
+    <Key>F7       thermal-mode
+    <Key>F8       arc-mode
+
+ +

+The <Key>Space cycles through all of the modes in the +mode button palette. + + +

+Reset-mode is really no mode, and <Btn1> has no effect with +this setting. +Some of the modes are very simple, such as the via-mode. Clicking +<Btn1> while in this mode creates a via at the cross-hair position. +The pastebuffer-mode is similar. With this mode, <Btn1> copies +the contents of the active buffer to the layout, but only +those parts that reside on visible layers are copied. +The rotate-mode allows you to rotate elements and text objects +90 degrees counter-clockwise with each click. +The line-mode is explained in detail in section Lines. +The arc-mode is explained in detainl in section Arcs. +Rectangle-mode, polygon-mode and thermal-mode are explained in detail in +section Polygons. +Remember that the thermal-mode will only create and destroy thermals +to polygons on the active layer. + + +

+The insert-point-mode is an editing tool that allows you to add +points into lines or polygons. With version 1.5 of Pcb, the +insert-point-mode enforces the 45 degree line +rule. You can force only the shorter line segment to 45 +degrees by holding the shift key down while inserting the point. +The delete-mode deletes the smallest object beneath the cursor with each +<Btn1> click. +If you use click at an end-point +that two lines have in common, it will replace the two lines with a single line +spanning the two remaining points. This can be used to delete an "inserted" +point in a line, restoring the previous line. + + +

+ + + +

Drawing Area

+

+The drawing area is made from a viewport widget that also includes two +scrollbars. The cursor changes shape depending +on the current operation mode when the pointer is moved into the drawing area. +A crosshair follows the X11 pointer with respect to the grid setting. +Move around and watch the cursor position displayed in the upper right of +the window. +Now select a new grid from the Display menu. +The new value is updated in the statusline. +Now move again and watch the difference. A different way to change the grid is +Shift<Key>g to decrease or <Key>g to increase +it. The grid setting is saved along with the data when you save a pcb layout. +For homemade layouts a value around 50 is a good setting. +The cursor also may be moved with the cursor keys or, for larger +distances, by pressing the shift modifier together with a cursor key. + + +

+ + + + +

Menu

+

+The menus are located at the top of the drawing area. Most, but not all, +of their functions are also available from the keyboard. +Some of the entries such as center require a certain cursor position. +In this case a statusline will popup at the bottom with wording similar to +the following: + +

+    move pointer to the appropriate screen position and press a button
+
+ +

+Any mouse button will do the job, whereas any key except the cursor keys +will cancel the operation. For details see section Actions. + + +

+ +
`About' +
+ + +There is no menu hiding behind this button, but a small information box will +pop up. + + +
`File' +
+This menu offers a choice of loading, saving and printing data, saving +connection information to a file or quitting the application. +You also may change the layout's or the active layer's name. Selecting +print layout pops up a printer control dialog which is, hopefully, +self explaining. This box contains a panner widget (only X11R5 and later) +which simplifies adjusting the offsets. With earlier releases the printout +will always appear in the upper left corner with respect to the media margins. + +A selection of several device drivers is available from the printer control +dialog. Presently PostScript, encapsulated PostScript, +and GerberX are supported. GerberD support may be forthcoming. +It requires a rastering engine that pcb presently lacks. + + + + + + + +
`Display' +
+The display menu supports the most needed functions related to +screen output. The entries are used to change the grid to some popular +values, the zoom factor, the displayed element name and also are used +to center or refresh the output. +You also may switch grid-displaying on or off and select between +absolute grid (origin at (0,0)) or relative grid (origin at the position where +the grid has been changed). The relative grid position is now +established at the actual pointer position, NOT necessarily the same +as the crosshair position. This allows you to shift the grid without +changing the grid spacing. I recommend that you zoom in as close as +possible before setting a relative grid so that you're sure the grid +lines fall where you want. +The clipping to 45-degree lines is selected in this menu, as well as +enabling rubberband mode (see description of Mode). + + +
`Sizes' +
+This menu allows you to select a group of line thickness, via diameter and via drill +size (collectively called a "routing style") to be coppied to the "active" sizes. +You can also change the names given to these styles and adjust their values from +this menu. You can also edit the "active" sizes (the initial size of new vias, +drilling holes, lines, text-objects and the current maximum size of the layout) +from this menu. + + + + +
`Objects' +
+Displaying the pinout of an element and changing its names, the one +that is currently selected by the Display menu, as well as +editing a text object is offered by this menu. The latter two selections +require an additional pointer button click at the object's position. +A dialog for changing the layer groupings is also reached from this +menu. + + + + + + +
`Selection' +
+This menu covers most of the operations that work with selected objects. +You may either (un)select all visible objects of a layout or only the ones +which have been found by the last connection scan. The mouse can also +be used to change which things are and are not selected: +toggle the selection of a single object by pressing +<Btn3Down> and releasing without moving the mouse. +Pressing Mod1<Btn3Down>, moving and +releasing the button selects all visible objects inside the +rectangle. Pressing the modifier key Shift too, unselects all +objects in the area. You can delete all selected objects from this +menu, and also move selected text objects to the silk-screen layer. +The other entries change the sizes of visible and selected objects. + + + +
`Buffer' +
+This menu handles pastebuffer related actions. You may select one out of five +(per viewing side) buffers to use, rotate or clear its contents and paste +it to the layout. You can also gather objects in the buffer into an element definition +from this menu. +Note: only visible objects are pasted to the layout. + + +
`Connections' +
+The entries available through the connections menu button allow the user to find +connections from pins or vias and to manipulate these. +The connection lists may be saved by selecting entries from the +File menu. In many cases it is desireable to use the ratsnest +function to check connections against a netlist file instead of using the +connections menu to generate text connection lists. + + +
`Undo' +
+This menu is a frontend for managing the reversing of operations +such as remove, copy, move, name changes, etc. The number of +operations is unlimited (depending on memory). The list is cleared if +new layout data is loaded or by selecting the appropriate entry from +this menu. The inverse operation, redo, is also available. + + +
`Report' +
+This menu allows you to generate a dialog that summerizes information +about an object such as sizes and coordinates. You can also get a report +about all of the drills that are used on the board. + +
+ +

+ + + + +

Log Window

+

+This optional window is used to display all kind of messages including +the ones written to stderr by external commands. The main advantage is +that its contents are saved in a scrolling list until the +program exits. Disabling this feature by setting the resource +useLogWindow to false will generate popup windows to display +messages. The stderr of external commands will appear on Pcbs +stderr which normally is the parent shell. I suggest you iconify +the window after startup for example by setting *log.iconic to +true. If raiseLogWindow is set true, +the window will deiconify and raise itself whenever new messages are to be +displayed. + + +

+ + + +

Library Window

+

+First appearing in 1.4.1 the library window is one of the best new features +in my opinion. It simplifies loading circuits quiet a lot just by selecting +the appropriate type from the menu at the top. A circuit is then selected +by simply double-clicking on the text line. For details on libraries +check-out section Library File Format and section Library Contents File Format. + + +

+ + + + + + +

Drawing and Removing Basic Objects

+

+There are several ways of creating new objects: you may draw them yourself, +you may copy an existing object or you may load an element from a file or +library. Creating new objects is normally related to a special +mode depending on the object type. +The notation of key and button events is the same as described in the +X11 Intrinsics manual. + + +

+The operation mode may be selected by one of the mode selectors in the bottom +left corner, by one of the function keys listed earlier in this chapter, +or by pressing the space bar to cycle through the modes. +<Btn1Down> sends a notify request to the application which +responds by creating or changing the appropriate object or at least takes +the first step to do so. Switching to a mode causes the cursor to take +on a unique shape and also causes the cooresponding +mode selector button to be drawn with thick lines. You can use either cue +to see which mode is currently selected. + + +

+Removing objects is possible using <Key>BackSpace (or <Key>Delete +on some machines) +which deletes the object at the cursor location. If more than one object +is located at the same position, the smallest matching type will be chosen. +If two or more of the same type are the smallest at the position, then the +newest one will be deleted. +You also may change to remove-mode and click <Btn1Down> +at the location of the objects which are to be removed. If you "remove" +the end-point where two lines connect, it will remove the point of +connection leaving a single line that spans the far end points. + + +

+Rotating works in a similar fashion. Change the mode and press +<Btn1Down> at the object's location. Remember only text, +elements and arcs can be rotated. (Anything including groups of objects +may be rotated inside a buffer using the rotate buffer menu option.) + + +

+Insert mode provides the capability of inserting new points into existing +polygons or lines. The 45 degree line clipping is now enforced when selected. +Press and hold the shift key while positioning the new point to only clip +the line segment to the nearer of the two existing points to 45 degrees. +You can also toggle the 45-degree clipping in the middle of a point +insertion by pressing the <Key>. +If the shift key is not depressed and the 45 degree line clipping mode +is on, both new line segments must be on 45 degree angles - greatly +restricting where the new point may be placed. In some cases this can cause +confusion as to whether an insertion has been started since the two new +lines may be forced to lie parallel on top of the original line until the +pointer is moved far from the end points. + + +

+Removing objects, changing their size or moving them only applies to objects +that are visible when the command is executed. + + + +

+ +

+ + + + + + +There are several keystrokes and button events refering to an object +without identifying its type. Here's a list of them: + + +

+<Btn1Down> creates (or deletes) an object depending on the +current mode. + + +

+<Key>BackSpace or <Key>Delete removes the visible +object at the cursor location. When more than one object exists at the +location, the order of removal is: via, line, text, polygon and +element. The drawn layer order also affects the search - whatever is +top - most (except elements) is affected before lower items. Basically +all this means that what is removed is probably just what you expect. +If for some reason it isn't, undo and try again. +Only one object is removed for each keystroke. If two or more +of the same type match, the newest one is removed. + + +

+Use <Key>s and Shift<Key>s to change the size (width) +of lines, arcs, text objects, pins, pads and vias, or to toggle the style +of polygons (whether pins and vias automatically have clearances). + + +

+<Key>n changes the name of pins, pads, vias, the +string of a text object, or the currently displayed label of an element. + + +

+<Key>m moves the line, arc, or polygon under the crosshair to the +active layer if it wasn't on that layer already. + + +

+<Key>u (undo) recovers from an unlimited number of operations +such as creating, removing, moving, copying, selecting etc. It works like +you'd expect even if you're in the midst of creating something. + + +

+Shift<Key>r restores the last undone operation provided no other +changes have been made since the undo was performed. + + +

+<Key>tab changes the board side you are viewing. + + +

+For a complete list of keystrokes and button events see section Default Translations. + + +

+ + + + +

Lines

+

+To draw new lines you have to be in line-mode. Get there either by +selecting it from the Tool palette or by pressing <Key>F2. +Each successive notify event creates a new line. The +adjustment to 45 degree lines is done automatically if it is selected from the +Display menu. You can toggle the 45 degree mode setting by +pressing the <Key>. (That is the period key). When 45 degree enforcement +is turned on there are three distinct modes of line creation: a single +line on the closest 45 degree vector towards the crosshair (but not necessarily +actually ending at the crosshair), two lines created such that the first leaves +the start point on a 90 degree vector and the second arrives at the crosshair +on a 45 degree vector, and finally two lines created such that the first leaves +the start point on a 45 degree vector and the second arrives at the crosshair +on a 90 degree vector. These last two modes always connect all the way from +the start and end points, and all lines have angles in 45 degree multiples. +The <Key>/ cycles through the three modes. The status line shows a +text icon to indicate which of the modes is active and the lines following +the crosshair motion show the outline of the line(s) that will actually be created. +Press <Key>Escape to leave line-mode. + + +

+<Key>l, Shift<Key>l and the entries in the +Sizes menu change the initial width of new lines. This width is also +displayed in the status line. + + +

+ + + +

Arcs

+

+An Arc is drawn with the arc-tool. Get there either by selecting it +from the Tool palette or by pressing <Key>F8. Press Btn1 to +define the starting point for the arc. Drag the mouse towards the desired +end point along the path you want the arc to follow. The outline of the arc that +will be created is shown on the screen as you move the mouse. Arcs are always +forced to be 90 degrees and have symmetrical length and width ( i.e. they are +a quarter circle). The next Btn1 click creates the arc. It will have +the same width as new lines (displayed in the status line) and appear on the +active layer. The arc leaves the starting point towards the crosshair along +the axis whose distance from the crosshair is largest. Normally this means that +if you drag along the path you want the arc to follow, you'll get what you +want. If the grid is set to the arc radius, then the two distances will be +equal and you won't be able to get all of the possible directions. If this +is thwarting your desires, reduce the grid spacing (!Shift<Key>G) and +try again. + + +

+ + + + + + +

Polygons and Rectangles

+

+A polygon is drawn by defining all of its segments as a series of +consecutive line segments. If the first point matches a new one and if +the number of points is greater than two, then the polygon is closed. +Since matching up with the first point may be difficult, you may use +Shift<Key>p to close the polygon. The Shift<Key>p won't +work if clipping to 45 degree lines is selected +and the final segment cannot match this condition. +I suggest you create simple convex polygons in order to avoid a strong +negative impact on the performance of the connection scanning routines. +The rectangle-mode is just an easy way to generate rectangular polygons. +Polygon-mode also is selected by <Key>F6 whereas +rectangle-mode uses <Key>F4. +Pressing a <Btn1Down> at two locations creates a rectangle by +defining two of its corners. +<Key>Insert brings you to insert-point-mode which lets you +add additional points to an already existing polygon. +Single points may be removed by moving the crosshair to them and selecting +one of the delete actions (remove-mode, BackSpace, or Delete. This only works +if the remaining polygon will still have three or more corners. +Pressing <Key>u or <Key>p while entering a new polygon +brings you back to the previous corner. Removing a point does not +force clipping to 45 degree angles (because it's not generally possible). +Newly created polygons will not connect to pins or vias +that pierce it unless you create a thermal (using the thermal mode) to make +the connection. If the edge of a polygon gets too close to a pin or via that +lies outside of it, a warning will be issued and the pin will be given a +special color. Increasing the distance between them will remove the warning +color. + + + + +

Text

+

+ + + +Pressing <Key>F5 or clicking one of the text selector buttons +changes to text-mode. +Each successive notify event (<Btn1Down>) +pops up the input line at the bottom and queries for a string. +Enter it and press <Key>Return to confirm or +<Key>Escape to abort. +The text object is created with its upper left corner at the current pointer +location. +The initial scaling is changed by <Key>t and +Shift<Key>t or from the Sizes menu. + + +

+Now switch to rotate-mode and press +<Btn1Down> at the text-objects location. Text objects +on the solder side of the layout are automatically mirrored and +flipped so that they are seen correctly when viewing the solder-side. + + +

+Use <Key>n to edit the string. + + +

+TEXT OBJECTS ON COPPER LAYERS CREATE COPPER LINES BUT THEY ARE NOT SCANNED FOR +CONNECTIONS. If they are moved to the silkscreen layer, they +no longer create copper. + + +

+ + + + +

Vias

+

+The initial size of new vias may be changed by <Key>v and +Shift<Key>v or by selecting the appropriate entry from the +Sizes menu. Mod1<Key>v and Mod1 Shift<Key>v do +the same for the drilling hole of the via. +The statusline is updated with the new values. +Creating a via is similar to the other objects. Switch to via-mode +by using either the selector button or <Key>F1 then press +<Key>] or <Btn1Down> to create one. +<Key>n changes the name of a via. If you want to create a mounting +hole for your board, then you can place a via where you want the hole to +be then convert the via into a hole. The conversion is done by pressing +!Ctrl<Key>h with the crosshair over the via. Conceptually it is +still a via, but it has no copper annulus. If you create such a hole in +the middle of two polygons on different layers, it will short the layers. +Theoretically you could arrange for such a hole not to be plated, but a +metal screw inserted in the hole would still risk shorting the layers. +A good rule is to realize that holes in the board really are vias between +the layers and so place them where they won't interfere with connectivity. +You can convert a hole back into a normal via with the same keystroke used +to convery it in the first place. + + +

+ + + + +

Elements

+

+Some of the functions related to elements only work if both the package +layer and the pin layer are switched on. + + +

+Now that you're familiar with many of the basic commands, it is +time to put the first element on the layout. +First of all, you have to load data into the paste buffer. +There are four ways to do this: + +

+   1) load the data from a library
+   2) load the data from a file
+   3) copy data from an already existing element
+   4) convert objects in the buffer into an element
+
+ +

+We don't have any elements on the screen yet nor anything in the +buffer, so we use number one. + + +

+ + +Select lsi from the menu in the library window press +<Btn1Down> twice at the appropriate text-line to get +the MC68030 CPU. +The data is loaded and the mode is switched to pastebuffer-mode. +Each notify event now creates one of these beasts. Leave the mode +by selecting a different one or by <Key>Escape which resets +all modes.. +The crosshair is located at the mark position as defined by +the data file. Rotating the buffer contents is done by selecting +the rotate entry of the Buffer menu or by pressing +Shift<Key>F3. The contents of the buffer +are valid until new data is loaded into it either by a cut-to-buffer +operation, copy-to-buffer operation or by loading a new data file. +There are 5 buffers +available. Switching between them is done by selecting a menu entry or +by Shift<Key>1..5. +Each of the two board sides has its own buffers. + + +

+The release includes all data files for the circuits that are used +by the demo layout. The elements in the LED example are not found in the library, +but you can lift them from the example itself if you want. +If you have problems with the color of the crosshair, change the resource +crosshairColor setting to a different one. + + +

+ + + +Now load a second circuit, the MC68882 FPU for example. +Create the circuit as explained above. You now have two different unnamed +elements. Unnamed means that the layout-name of the element +hasn't been set yet. Selecting description from the Display +menu displays the description string of the two circuits which +are CPU and FPU. The values of the circuits are set to MC68030 and MC68882. +Each of the names of an element may be changed +by <Key>n at the elements location and editing the old name in +the bottom input line. Naming pins and vias is similar to elements. +You can hide the element name so that it won't appear on the board +silkscreen by pressing <key>h with the cursor over the element. +Doing so again un-hides the element name. + + +

+Entering :le and selecting an element data file is +the second way to load circuits. + + +

+The third way to create a new element is to copy an existing one. +Please refer to section Moving and Copying. + + +

+ + + + +The fourth way to create a new element is to convert a buffer's contents +into an element. Here's how it's done: Select the Via-tool from the +Tool pallette. Set the grid spacing to something appropriate for +the element pin spacing. Now create a series of vias where the pins +go. Create them in pin number order. It is often handy to place a reference +point (!Ctrl<Key>m) in the center of the first pin in order to measure +the location of the other pins. Next make a solder-side layer the active +layer from the active-layer popup menu. Now draw the outline of +the element using lines and arcs. When you're done, select everything that +makes up the element with a box selection (<Btn3Down> drag, +<Btn3Up>). Now select "cut selection to buffer" from the Buffer +menu. Position the cursor over the center of pin 1 and press the left +button to load the data into the buffer. +Finally select "convert buffer to element" from the Buffer menu. +You'll only want to create elements this way if they aren't already in the +library. It's also probably a good idea to do this before starting any of +the other aspects of a layout, but it isn't necessary. + + +

+To display the pinout of a circuit move to it and press Shift<Key>d +or select show pinout from the Objects menu. A new window +pops up and displays the complete pinout of the element. This display can +be difficult to read if the component has been rotated 90 degrees :-( +therefore, the new window will show an un-rotated view so the pin names +are readable. +<Key>d displays the name of one or all pins/pads inside the +drawing area, this is only for display on-screen, it has no effect on any +printing of the layout. + + +

+You also may want to change a pin's or pad's current size by pressing +<Key>s to increase or Shift<Key>s to decrease it. While +this is possible, it is not recommended since care was probably taken +to define the element structure in the first place. You can also change the thickness +of the element's silkscreen outline with the same keys. You can +change whether a pin or SMD pad is rounded or square with the <Key>q. +SMD pads should usually have squared ends. Finally, you can change whether +the non-square pins are round or octagonal with the !Ctrl<Key>o. + + +

+SMD elements and silkscreen objects are drawn in the "invisible object" +color if they are located on the opposite side of the board. + + +

+For information on element connections refer to section Connection Lists. + + +

+ + + + + + +

Pastebuffer

+

+The linestack and element-buffer of former releases have been replaced +by 5 multi-purpose buffers that are selected by +Shift<Key>1..5. The status line shows which buffer is +the active one. +You may load data from a file or layout into them. +Cut-and-paste works too. +If you followed the instructions earlier in this chapter you should +now have several objects on the screen. Move the crosshair to one of them +and press <Btn3Down> to toggle its selection flag. (If you drag the +mouse while the button is down, a box selection will be attempted instead +of toggling the selection.) The object +is redrawn in a different color. You also may want to try +moving the pointer while holding the third button down and +release it on a different location. This selects all objects inside the +rectangle and unselects everything else. If you want to add a box selection +to an existing selection, drag with Mod1<Btn3Down> instead. +Dragging Shift Mod1<Btn3Down> unselects objects in a box. +Now change to pastebuffer-mode and select some operations from the +Buffer menu. Copying objects to the buffer is available as +Mod1<Key>c while cutting them uses Mod1<Key>x as +shortcut. Both clear the buffer before new data is added. +If you use the menu entries, you have to supply a crosshair position by +pressing a mouse button. The objects are attached to the pastebuffer +relative to that crosshair location. +Element data or PCB data may be merged into an existing layout by loading +the datafiles into the pastebuffer. Both operations are available from +the File menu or as user commands. + + + + +

Moving and Copying

+

+ + + + +All objects can be moved including element-names, by +<Btn2Down>, draging the pointer while holding the button down +and releasing it at the new location of the object. If you use +Mod1<Btn2Down> instead, the object is copied. Copying does not work for +element-names of course. You can move all selected objects with +Shift <Btn1Down>. This uses the Pastebuffer, so +it will remove whatever was previously in the Pastebuffer. +Please refer to section Pastebuffer. +If you want to give a small nudge to an object, but you don't think +that the mouse will give you the fine level of control that you want, +you can position the cursor over the object, press <Key>[, +move it with the arrow keys, then press <Key>] when it's at the +desired position. Remember that all movements are forced onto grid coordinates, so +you may want to change the grid spacing first. + + + + +

Loading and Saving

+

+ + + + +After your first experience with Pcb you will probably want to save +your work. :s name passes the data to an external program which +is responsible for saving it. For details see saveCommand in +section Non-Standard X11 Application Resources. +Saving also is available from the File menu, either with or +without supplying a filename. Pcb reuses the last +filename if you do not pass a new one to the save routine. + + +

+To load an existing layout either select load layout data from the +File menu or use :l filename. A file select box pops up if you +don't specify a filename. Merging existing layouts into the new one is +supported either by the File menu or by :m filename. + + +

+ + + + + + +Pcb saves a backup of the current layout depending on the resource +backup. The file is named `/tmp/PCB.%i.backup'. During critical +sections of the program or when data would be lost it is saved as +`/tmp/PCB.%i.save'. +%i is replaced by the process ID. + + +

+ + + + +

Printing

+

+Pcb now has support for device drivers, +PostScript, encapsulated PostScript, +and Gerber X drivers are +available so far. The Gerber X +driver generates a NC drill file for automated drilling. + I recommend the use of GhostScript if you +don't have a PostScript printer for handling the PostScript +output. Printing always generates +a complete set of files for a specified driver. +See the page about +the Print() action for addtional information about the filenames. +The control panel offers a number of options. Most of them are not avilable +for Gerber output because it wouldn't make sense, for example, to scale the gerber output +(you'd get an incorrectly made board!) The options are: + + +

+ +
`device' +
+ + + +The top menu button selects from the available device drivers. + + +
`rotate' +
+Rotate layout 90 degrees counter-clockwise before printing (default). + + +
`mirror' +
+Mirror layout before printing. Use this option depending +on your production line. + + +
`color' +
+Created colored output. All colors will be converted to black if this option +is inactive. + + +
`outline' +
+Add a board outline to the output file. The size is determined by the +maximum boardsize changeable from the sizes menu. The outline appears +on the top and bottom sides of the board, but not on the internal layers. +An outline can be useful for determining where to shear the board from the +panel, but be aware that it creates a copper line. Thus it has the potential +to cause short circuits if you don't leave enough room from your wiring +to the board edge. Use a viewer to see what the output outline looks like +if you want to know what it looks like. + + +
`alignment' +
+Additional alignement targets are added to the output. The distances between +the board outline is set by the resource alignmentDistance. Alignment +targets should only be used if you know for certain that YOU WILL BE USING +THEM YOURSELF. It is extremely unlikely that you will want to have alignment +targets if you send gerber files to a commercial pcb manufacture to be made. + + +
`scaling' +
+It's quite useful to enlarge your printout for checking the layout. +Use the scrollbar to adjust the scaling factor to your needs. + + + +
`media' +
+Select the size of the output media from this menu. The user defined size +may be set by the resource media either from one of the well known +paper sizes or by a X11 geometry specification. +This entry is only available if you use X11R5 or later. +For earlier releases the user defined size or, if not available, A4 +is used. +Well known size are: + +
+	A3
+	A4
+	A5
+	letter
+	tabloid
+	ledger
+	legal
+	executive
+
+ + + +
`offset' +
+Adjust the offsets of the printout by using the panner at the right side +of the dialog box. +This entry is only available if you use X11R5 or later. A zero +offset is used for earlier releases. + + +
`8.3 filenames' +
+Select this button to generate DOS compatible filenames for the output files. +The command input area will disappear if selected. + + +
`commandline' +
+Use this line to enter a command (starts with |) or a filename. +A %f is replaced by the current filename. +The default is set by the resource printCommand. + +
+ +

+The created file includes some labels which are guaranteed to stay unchanged +

+ +
`PCBMIN' +
+identifies the lowest x and y coordinates in mil. + +
`PCBMAX' +
+identifies the highest x and y coordinates in mil. + +
`PCBOFFSET' +
+is set to the x and y offset in mil. + +
`PCBSCALE' +
+is a floating point value which identifies the scaling factor. + +
`PCBSTARTDATA' +
+
`PCBENDDATA' +
+all layout data is included between these two marks. You may use them with an +awk script to produce several printouts on one piece of paper by +duplicating the code and putting some translate commands in front. +Note, the normal PostScript units are 1/72 inch. +
+ +

+ + + + +

Connection Lists

+

+After completing parts of your layout you may want to check if all drawn +connections match the ones you have in mind. This is probably best done +in conjunction with a net-list file: see section Rats Nest. +The following examples give more rudimentary ways to examine +the connections. + +

+    1) create at least two elements and name them
+    2) create some connections between their pins
+    3) optionally add some vias and connections to them
+
+ +

+Now select lookup connection from the Connections menu, +move the cursor to a pin or via and press any mouse button. Pcb +will look for all other pins and/or vias connected to the one you have +selected and display the objects in a different color. +Now try some of the reset options available from the same menu. + + +

+There also is a way to scan all connections of one element. Select +a single element from the menu and press any button at the +element's location. All connections of this element will be saved +to the specified file. +Either the layout name of the element or its canonical name is used to +identify pins depending on the one which is displayed on the screen +(may be changed by Display menu). + + +

+An automatic scan of all elements is initiated by choosing +all elements. It behaves in a similar fashion to scanning a single +element except the resource resetAfterElement +is used to determine if connections should be reset before a new element is +scanned. Doing so will produce very long lists because the power lines are +rescanned for every element. By default the resource is set to false +for this reason. + + +

+To scan for unconnected pins select unused pins from the same +menu. + + +

+ + + +

Selection

+

+Some commands mentioned earlier in this chapter also are able to operate on all +selected and visible objects. +Now go back to the layout and toggle the selection flag of a single one +by <Btn3Down>. Try <Btn3Down>, move the pointer while +holding the button down and release it on a different location. +This selects all objects inside the rectangle and unselects everything else. +Dragging with Mod1<Btn3Down> adds everything in the box to the +existing selection. Dragging Shift <Btn3Down> unselects objects in the +box. + + +

+The entries of the Selection menu are hopefully self-explanatory. +Many of the Action Commands can take various key words that make +them function on all or some of the selected items. + + +

+ + + + + +

Rats Nest

+

+If you have a netlist that corresponds to the layout you are working on, you +can use the rats-nest feature to add rat-lines to the layout. +First you will need to load a netlist file (see :rn, +section User Commands). +<Key>w adds rat-lines on the active layer using the current +line thickness shown in the status line (usually you'll want them to be thin lines). +Only those rat-lines that fill in missing connectivity (since you have +probably routed some connections already) are added. +If the layout is already completely wired, nothing will be added, and you will +get a message that the wiring is complete. + + +

+Rat-lines are lines having the special property that they only connect to pins and +pads at their end points. Rat-lines are drawn on the screen with a stippled pattern +to make them easier to identify since they have special behavior and cannot +remain in a completed layout. +Rat-lines are added in the minimum length straight-line tree pattern +(always ending on pins or pads) that satisfies the missing connectivity in the circuit. +Used in connection with moves and rotates of the elements, they are extremely useful for +deciding where to place elements on the board. The rat-lines will always automatically +rubberband to the elements whether or not the rubberband mode is on. The only way for +you to move them is by moving the parts they connect to. +This is because it is never desireable to have the rat-lines disconnected from +their element pins. Rat-lines will normally criss-cross +all over which gives rise to the name "rats nest" describing a layout connected with +them. If a SMD pad is unreachable on the active layer, a warning will be issued +about it and the rat-line to that pad will not be generated. + + +

+A common way to use rats nests is to place some +elements on the board, add the rat-lines, and then use a series of moves/rotates of the +elements until the rats nest appears to have minimum tangling. You may want to iterate this step +several times. Don't worry if the layout looks messy - as long as you can get a sense for whether +the criss-crossing is better or worse as you move things, you're fine. +After moving some elements arround, you may want to optimize the rats nest <Key>o +so that the lines are drawn between the closest points (this can change once you've moved components). +Adding rat-lines only to selected pads/pins (Shift<Key>w) +is often useful to layout a circuit a little bit at a time. +Sometimes you'll want to delete all the rat-lines (<Key>e) or +selected rat-lines (Shift<Key>e) in order to reduce confusion. +With a little practice you'll be able to achieve a near optimal component placement with +the use of a rats nest. + + +

+Rat-lines are not only used for assisting your element placement, they can also help +you to route traces on the board. +Use the <Key>m to convert a rat-line under the cursor into +a normal line on the active layer. +Inserting a point into a rat-line will also cause the two new lines to be normal lines +on the board. +Another way that you can use rat-lines is to +use the <Key>f with the cursor over a pad or pin. All of the pins and +pads and rat-lines belonging to that net will be highlighted. This is a helpful way to +distinguish one net from the rest of the rats nest. You can then route those tracks, +turn off the highlighting (Shift<Key>f) and repeat the process. This will work even +if the layer that the rat-lines reside on is made invisible - so only the pins and pads +are highlighted. +Be sure to erase the rat-lines (<Key>e erases them all) once you've +duplicated their connectivity by adding your own lines. +When in doubt, the <Key>o will delete only those +rat-lines that are no longer needed. + + +

+If connections exist on the board that are not listed in the netlist when +<Key>w is pressed, warning messages are issued and the affected pins and +pads are drawn in a special warnColor until the next Notify() event. +If the entire layout agrees completely with the netlist, a message informs you that +the layout is complete and no rat-lines will be added (since none are needed). +If the layout is complete, but still has rat-lines then you will be warned +that rat-lines remain. If you get no message at all it's probably because some +elements listed in the net list can't be found and where reported in an earlier +message. +There shouldn't be any rat-lines left in a completed layout, only normal lines. + + +

+The Shift<Key>w is used to add rat-lines to only those missing connections among +the selected pins and pads. This can be used to add rat-lines in an incremental +manner, or to force a rat-line to route between two points that are not the +closest points within the net. Often it is best to add the rats nest in an incremental fashion, laying +out a sub-section of the board before going further. This is easy to accomplish since +new rat-lines are never added where routed connectivity already makes the necessary +connections. + + +

+ + + + + + +

Design Rule Checking

+

+After you've finished laying out a board, you may want to check +to be certain that none of your interconnections are too closely +spaced or too tenuously touching to be reliably fabricated. The design +rule checking (DRC) function does this for you. Use the command ":DRC()" (without +the quotes of course) to invoke the checker. If there are no problem areas, +you'll get a message to that effect. If any problem is encountered, you will get +a message about it and the affected traces will be highlighted. One part of the +tracks of concern will be selected, while the other parts of concern will have the +"FindConnection" highlighting. The screen will automatically be centered in the +middle of the object having the "FindConnection" (Green) highlighting. The middle of +the object is also the coordinates reported to be "near" the problem. The actual trouble +region will be somewhere on the boundary of this object. If the two parts are +from different nets then there is some place where they approach each +other closer than the minimum rule. If the parts are from the same net, then +there is place where they are only barely connected. Find that place and connect +them better. + + +

+After a DRC error is found and corrected you must run the DRC again because +the search for errors is halted as soon as the first problem is found. Unless you've +been extremely careless there should be no more than a few design rule errors +in your layout. The DRC checker does not check for minimum spacing rules to +copper text, so always be very careful when adding copper text to a layout. +The rules for the DRC are specified in the application resource file. The minimum +spacing value (in mils) is given by the Settings.Bloat value. The default +is 7 mils. The minimum touching overlap (in mils) is given by the +Settings.Shrink value. This value defaults to 5 mils. Check with your +fabrication process people to determine the values that are right for you. + + +

+If you want to turn off the highlighting produced by the DRC, perform an +undo (assuming no other changes have been made). To restore the highlighting, +use redo. The redo will restore the highlighting quickly without re-running +the DRC checker. + + +

+ + + + +

User Commands

+

+The entering of user-commands is initiated by the action routine +Command() (the (":") character) and finished by either +<Key>Return +or <Key>Escape to confirm or to abort. These two keybindings +cannot be changed from the resource file. +The triggering event, normally a key press, is ignored. +The input area will replace the bottom statusline. It pops +up when Command() is called. The arguments of the user-commands +are passed to the external commands without modification. +See also, the resource saveInTMP. + + +

+There are simple usage dialogs for each command and one for the +complete set of commands. + + +

+ +
`l [filename]' +
+ + + + +Loads a new datafile (layout) and, if confirmed, overwrites any existing unsaved data. +The filename and the searchpath (filePath) are passed to the +command defined by fileCommand. +If no filename is specified a file select box will popup. + + + + +
`le [filename]' +
+Loads an element description into the paste buffer. +The filename and the searchpath (elementPath) are passed to the +command defined by elementCommand. +If no filename is specified a file select box will popup. + + + + + + +
`m [filename]' +
+Loads an layout file into the paste buffer. +The filename and the searchpath (filePath) are passed to the +command defined by fileCommand. +If no filename is specified a file select box will popup. + + + + +
`q[!]' +
+Quits the program without saving any data (after confirmation). +q! doesn't ask for confirmation, it just quits. + + + + +
`s [filename]' +
+Data and the filename are passed to the command defined by the resource +saveCommand. It must read the layout data from stdin. +If no filename is entered, either the last one is used +again or, if it is not available, a file select box will pop up. + + + + + +
`rn [filename]' +
+Reads in a netlist file. If no filename is given +a file select box will pop up. +The file is read via the command defined by the +RatCommand resource. The command must send its output to stdout. +The netlist received by pcb must have this simple text form: + +netname NAME-PINNUM NAME2-PINNUM2 NAME3-PINNUM3 ... [\] + +where "netname" is the name of the net (currently its value is ignored but +it must be present nonetheless), +NAME is the layout-name given to an element, and PINNUM is the (usually numeric) +pin number of the element that is part of the net (see section Elements +for details on pin numbering). +Spaces or tabs separate the fields. +If the line ends with a "\" the +net continues on the next line and the "\" is treated exactly as if it +were a space. If the NAME ends with a lower-case letter, +all lower-case letters are stripped from end of the NAME to determine the +matching name-on-board name. For example: + +Data U1-3 U2abc-4 FLOP1a-7 Uabc3-A9 + +would specifiy that pin 3 of U1 be connected to pin 4 of U2, to pin 7 of +FLOP1 and to pin A9 of Uabc3. Note that if pin numbers contain alphabetic +characters, they must match the case contained in the "number" string defining the +pin number on the cooresponding element. +It is up to you to name the elements so that their layout-names agrees with the netlist. +Netlists are used for generating rats nest (see section Rats Nest) and for +verifying the board layout (which is also accomplished by the Ratsnest +command. + + + + +
`w[q] [filename]' +
+These commands have been added for the convenience of vi users and +have the same functionality as s combined with q. + + + + +
`actionCommand' +
+Causes the actionCommand to be executed. This allows you to initiate actions +for which no bindings exist in the resource file. It can be used to initiate any +action with whatever arguments you enter. This makes it possible to do things +that otherwise would be extremely tedious. For example, to change the drilling +hole diameter of all vias in the layout to 32 mils, you could select everything using the +selection menu, then type ":ChangeDrillSize(SelectedVias, 32)". (This will +only work provided the via's diameter is sufficiently large to accomodate a 32 mil hole). +Another example might be to set the grid to 1 mil by typing ":SetValue(Grid, 1)". +Note that some actions use the current cursor location, so be sure to place the cursor +where you want before entering the command. This is one of my favorite new +features in 1.5 and can be a powerful tool. Study the section Actions section to +see what actions are available. + +
+ +

+ + + + +

X11 Interface

+

+This chapter gives an overview about the additional X11 resources which +are defined by Pcb as well as the defined action routines. + + + +

+ +

+ + + + +

Non-Standard X11 Application Resources

+

+In addition to the toolkit resources, Pcb defines the +following resources: + + +

+ +
`absoluteGrid (boolean)' +
+ + + +Selects if either the grid is relative to the position where it has changed +last or absolute, the default, to the origin (0,0). + + + +
`alignmentDistance (dimension)' +
+Specifies the distance between the boards outline to the alignment targets. + + + + +
`allDirectionLines (boolean)' +
+Enables (default) or disables clipping of new lines to 45 degree angles. + + + +
`backupInterval (int)' +
+Pcb has an automatic backup feature which saves the current data +every n seconds. The default is 300 seconds. A value of zero disables +the feature. The backup file is named `/tmp/PCB.%i.backup'. +%i is replaced by the process ID. +See also, the command-line option -backup. + + + + +
`Bloat (dimension)' +
+Specifies the minimum spacing design rule in mils. + + + + + +
`charactersPerLine (int)' +
+Pcb uses this value to determine the page width when creating lists. +N, the number of characters per line, defaults to 80. +See also, the command-line option -c. + + + + +
`connectedColor (color)' +
+All pins, vias, lines and rectangles which are selected during a connection +search are drawn with this color. The default value is determined by +XtDefaultForeground. + + + + +
`crosshairColor (color)' +
+This color is used to draw the crosshair cursor. The color is a result of +a XOR operation with the contents of the drawing area. The result +also depends on the default colormap of the X11 server because only +the colormap index is used in the boolean operation and Pcb doesn't +create its own colormap. The default setting is XtDefaultForeground. + + + + + +
`elementColor (color)' +
+
`elementSelectedColor (color)' +
+The elements package part is drawn in these colors, for normal and selected +mode, respectively, which both default to XtDefaultForeground. + + + + + + + + +
`elementCommand (string)' +
+Pcb uses a user defined command to read element files. This resources +is used to set the command which is executed by the users default shell. +Two escape sequences are defined to pass the selected filename (%f) and the +current search path (%p). The command must write the element data +to its standard output. The default value is + +
+    M4PATH="%p";export M4PATH;echo 'include(%f)' | m4
+
+ +Using the GNU version of m4 is highly recommended. +See also, the command-line option -lelement. + + + + + + +
`elementPath (string)' +
+A colon separated list of directories or commands (starts with '|'). +The path is passed to the program specified in elementCommand together +with the selected elementname. A specified command will be executed in order +to create entries for the fileselect box. It must write its results to +stdout one entry per line. +See also, the user-command le[!]. + + + + + + + + +
`fileCommand (string)' +
+The command is executed by the user's default shell whenever existing layout +files are loaded. Data is read from the command's standard output. +Two escape sequences may be specified to pass the selected filename (%f) +and the current search path (%p). The default value is: + +
+    cat %f
+
+ +See also, the command-line option -lfile. + + + + + + +
`filePath (string)' +
+A colon separated list of directories or commands (starts with '|'). +The path is passed to the program specified in fileCommand together +with the selected filename. A specified command will be executed in order +to create entries for the fileselect box. It must write its results to +stdout one entry per line. +See also, the user-command l[!]. + + + + + + + + + +
`fontCommand (string)' +
+Loading new symbol sets also is handled by an external command. You again +may pass the selected filename and the current search path by passing +%f and %p in the command string. Data is read from the commands standard +output. This command defaults to + +
+    cat %f
+
+ +See also, the command-line option -lfont. + + + + +
`fontFile (string)' +
+The default font for new layouts is read from this file which is searched +in the directories as defined by the resource fontPath. +Searching is only performed if the filename does not contain a directory +component. +The default filename is `default_font'. +See also, the command-line option -fontfile. + + + + + + + +
`fontPath (string)' +
+This resource, a colon separated list of directories, defines the searchpath +for font files. See also, the resource fontFile. + + + + +
`grid (int)' +
+This resources defines the initial value of one cursor step. It defaults +to 100 mil and any changes are saved together with the layout data. + + + + +
`gridColor (color)' +
+This color is used to draw the grid. The color is a result of +a INVERT operation with the contents of the drawing area. The result +also depends on the default colormap of the X11 server because only +the colormap index is used in the boolean operation and Pcb doesn't +create its own colormap. The default setting is XtDefaultForeground. + + + + +
`elementColor (color)' +
+Elements localted on the opposite side of the board are drawn in this color. +The default is XtDefaultForeground. + + + + + +
`layerColor1..8 (color)' +
+
`layerSelectedColor1..8 (color)' +
+These resources define the drawing colors of the different layers in +normal and selected state. All values are preset to XtDefaultForeground. + + + + +
`layerGroups (string)' +
+The argument to this resource is a colon separated list of comma separated +layernumbers (1..8). All layers within one group are switched on/off +together. The default setting is 1:2:3:...:8 which means +all layers are handled separatly. Grouping layers one to three looks like +1,2,3:4:...:8 +See also, the command-line option -lg. + + + +
`layerName1..8 (string)' +
+The default name of the layers in a new layout are determined by these +resources. The defaults are empty strings. + + + + + +
`libraryCommand (string)' +
+Pcb uses a command to read element data from libraries. +The resources is used to set the command which is executed by the users +default shell. Three escape sequences are defined to pass the selected +filename (%f), the current search path (%p) as well (%a) as the three +parameters template, value and package to the command. +It must write the element data to its standard output. The default value is + +
+    /usr/X11R6/lib/X11/pcb/QueryLibrary.sh %p %f %a
+
+ + + + + +
`libraryContentsCommand (string)' +
+Similar to libraryCommand, Pcb uses the command specified +by this resource to list the contents of a library. + +
+	/usr/X11R6/lib/X11/pcb/ListLibraryContents.sh %p %f
+
+ +is the default. + + + + +
`libraryFilename (string)' +
+The resource specifies the name of the library. The default value is +pcblib. + + + + + +
`libraryPath (string)' +
+A colon separated list of directories that will be passed to the commands +specified by elementCommand and elementContentsCommand. + + + + + +
`lineThickness (dimension)' +
+The value, int the range [1..250], defines the +initial thickness of new lines. The value is preset to ten mil. + + + + + +
`media (<predefined> | <width>x<height>+-<left_margin>+-<top_margin>)' +
+The default (user defined) media of the PostScript device. Predefined +values are a3, a4, a5, letter, tabloit, +ledger, legal, and executive. +The second way is to specify the medias width, height and margins in mil. +The resource defaults to a4 size. + + + + +
`offLimitColor (color)' +
+The area outside the current maximum settings for width and height is drawn +with this color. The default value is determined by XtDefaultBackground. + + + + + +
`pinColor (color)' +
+
`pinSelectedColor(color)' +
+This resource defines the drawing color of pins and pads in both states. +The values are preset to XtDefaultForeground. + + + + +
`pinoutFont (string)' +
+This fonts are used to display pin names. There is one font for each zoom +value. The values are preset to XtdefaultFont. + + + + + +
`pinoutNameLength (int)' +
+This resource limits the number of characters which are displayed for +pin names in the pinout window. By default the string length is limited +to eight characters per name. +See also, the command-line option -pnl. + + + + +
`pinoutOffsetX (int)' +
+
`pinoutOffsetY (int)' +
+These resources determine the offset in mil of the circuit from the +upper left corner of the window when displaying pinout information. +Both default to 100 mil. + + + + +
`pinoutTextOffsetX (int)' +
+
`pinoutTextOffsetY (int)' +
+The resources determine the distance in mil between the drilling hole of a pin +to the location where its name is displayed in the pinout window. +They default to X:50 and Y:0. + + + + +
`pinoutZoom (int)' +
+Sets the zoom factor for the pinout window according to the formula: +scale = 1:(2 power value). Its default value is two which results in +a 1:4 scale. +See also, the command-line option -pz. + + + +
`printCommand (string)' +
+Default file for printouts. If the name starts with a '|' the output +is piped through the command. A %f is replaced by the current filename. +There is no default file or command. + + + + +
`raiseLogWindow (boolean)' +
+The log window will be raised when new messages arrive if this resource +is set true, the default. + + + + +
`ratCommand (string)' +
+Default command for reading a netlist. A %f is replaced by the netlist +filename. Its default value is "cat %f". + + + + +
`ratPath (string)' +
+Default path to look for netlist files. It's default value is "." + + + + +
`resetAfterElement (boolean)' +
+If set to true, all found connections will be reset before a new +element is scanned. This will produce long lists when scanning the whole +layout for connections. The resource is set to false by default. +The feature is only used while looking up connections of all elements. +See also, the command-line option -reset, +reset. + + + +
`ringBellWhenFinished (boolean)' +
+Whether to ring the bell (the default) when a possibly lengthy operation +has finished or not. +See also, the command-line option -ring, +ring. + + + +
`routeStyle (string)' +
+Default values for the menu of routing styles (seen in the sizes menu). +The string is a comma separated list of name, line thickness, +via diameter, and via drill size. +e.g. "Fat,50,100,40:Skinny,8,35,20:75Ohm,110,110,20" +See also, the command-line option -rs and Sizes Menu + + + + + +
`rubberBandMode (boolean)' +
+Whether rubberband move and rotate (attached lines stretch like +rubberbands) is enabled (the default). + + + + + + + + +
`saveCommand (string)' +
+This command is used to save data to a layout file. The filename may be +indicated by placing %f in the string. It must read the data from +its standard input. The default command is: + +
+    cat - > %f
+
+ +See also, the command-line option -sfile. + + + + + + + + +
`saveInTMP (boolean)' +
+Enabling this resource will save all data which would otherwise be lost +in a temporary file `/tmp/PCB.%i.save'. +%i is replaced by the process ID. +As an example, loading a new layout when the old one hasn't been saved would +use this resource. +See also, the command-line option -save, +save. + + + + +
`saveLastCommand (boolean)' +
+Enables the saving of the last entered user command. The option is +disabled by default. +See also, the command-line option -s, +s. + + + + +
`Shrink (dimension)' +
+Specifies the minimum overlap (touching) design rule in mils. + + + + +
`size (<width>x<height>)' +
+Defines the width and height of a new layout. The default is +7000x5000. + + + + +
`stipllePolygons (boolean)' +
+Determines whether to display polygons on the screen with a stippled +pattern. Stippling can create some amount of transperency so that +you can still (to some extent) see layers beneath polygons. +It defaults to False. + + + + +
`textScale (dimension)' +
+The font scaling in percent is defined by this resource. The default is +100 percent. + + + + +
`useLogWindow (boolean)' +
+Several subroutines send messages to the user if an error occurs. +This resource determines if they appear inside the log window or as a separate +dialog box. See also, the resource raiseLogWindow and the command line +option -loggeometry. +The default value is true. + + + + + +
`viaColor (color)' +
+
`viaSelectedColor (color)' +
+This resource defines the drawing color of vias in both states. +The values are preset to XtDefaultForeground. + + + + + + +
`viaThickness (dimension)' +
+
`viaDrillingHole (dimension)' +
+The initial thickness and drilling hole of new vias. The values must be in the +range [30..250] with at least 20 +mil of copper. +The default thickness is 40 mil and the default drilling hole is +20 mil. + + + + +
`volume (int)' +
+The value is passed to XBell() which sets the volume of the X +speaker. +The value lies in the range -100..100 and it defaults to the maximum volume of +100. + + + + +
`warnColor (color)' +
+This resources defines the color to be used for drawing pins and pads when +a warning has been issued about them. + + + +
`zoom (int)' +
+The initial value for output scaling is set according to the following +formula: scale = 1:(2 power value). It defaults to three which results +in an output scale of 1:8. + +
+ +

+Refer also to section Command-Line Options. + + +

+ + + + + + + +

Actions

+

+All user accessible commands may be bound to almost any X event. Almost +no default binding for commands is done in the binaries, so it is vital for the +application that at least a system-wide application resource file exists. +This file normally resides in the `X11/lib/app-defaults' directory and +is called `Pcb'. The bindings to which the manual refers to are the +ones as defined by the shipped resource file. Besides binding an action to +an X11 event, you can also execute any action command using a ":" command +(see section User Commands). + + +

+Take special care about translations related to the functions keys and the +pointer buttons because most of the window managers use them too. +Change the file according to your hardware/software environment. +You may have to replace all occurances of baseTranslations to +translations if you use a X11R4 server. + + +

+Passing Object as an argument to an action routine causes the object +at the cursor location to be changed, removed or whatever. If more than +one object is located at the crosshair position the smallest type is used. +If there are two of the same type the newer one is taken. +SelectedObjects will handle all selected and visible objects. + + +

+ +
`AddRats(AllRats|SelectedRats)' +
+ + + + + +Adds rat-lines to the layout using the loaded netlist file (see the :rn, +section User Commands.). Rat lines are added on the active layer using the current +line thickness shown in the status line. +Only missing connectivity is added by the +AddRats command so if, for example, the layout is complete nothing will be added. +Rat lines are drawn on the screen with a stippled pattern +to make them easier to identify since they cannot appear in a completed layout. +The rat-lines are added in the minimum length straight-line tree pattern +(always ending on pins or pads) that satisfies the missing connectivity in the circuit. +If a SMD pad is unreachable on the active layer, a warning will be issued +about it and the rat-line to that pad will not be generated. +If connections exist on the board which are not listed in the netlist while +AllRats are being added, warning messages will be issued and the affected pins and +pads will be drawn in a special warnColor until the next Notify() event. +If the entire layout agrees completely with the net-list a message informs you that +the layout is complete and no rat-lines are added (since none are needed). +If SelectedRats +is passed as the argument, only those missing connections that might connect among +the selected pins and pads are drawn. +Default: + +
+None<Key>w:	AddRats(AllRats)
+!Shift<Key>w:	AddRats(SelectedRats)
+None<Key>o:	DeleteRats(AllRats) AddRats(AllRats)
+!Shift<Key>o:	DeleteRats(SelectedRats) AddRats(SelectedRats)
+
+ + + + +
`Atomic(Save|Restore|Block|Close)' +
+Controls the undo grouping of sequences of actions. Before the first action +in a group, Atomic(Save) should be issued. After each action that might +be undoable, Atomic(Restore) should be issued. Atomic(Block) concludes +and save the undo grouping if there was anything in the group to undo. +Atomic(Close) concludes and save the undo grouping even if nothing was +actually done. Thus it might produce an "empty" undo. This can be useful +when you want to use undo in a group of actions. + + + + +
`Bell([-100..100])' +
+Rings the bell of your display. If no value is passed the setting +of the resource volume will be used. + + + + + +
`ChangeDrillSize(Object, value)' +
+
`ChangeDrillSize(SelectedPins|SelectedVias, value)' +
+This action routine changes the drilling hole of pins and vias. +If value starts with + or -, then it adds (or subtracts) +value from the current hole diameter, otherwise it sets the +diameter to the value. +Default: + +
+!Mod1<Key>s:       Change2ndSize(Object, +5)
+!Mod1 Shift<Key>s: Change2ndSize(Object, -5)
+
+ + + + +
`ChangeHole(Object|SelectedVias)' +
+This action routine converts a via to and from a hole. A hole is +a via that has no copper annulus. The drill size for the via +determines the hole diameter. + +
+!Ctrl<Key>h:	ChangeHole(Object)
+
+ + + + + +
`ChangeName(Object)' +
+
`ChangeName(Layer|Layout)' +
+Changes the name of the visible object at the cursor location. A text object +doesn't have a name therefore the text string itself is changed. +The element name currently used for display is always the one changed with this +command. +See Display(Description|NameOnPCB|Value) for details. +Passing Layer changes the current layers name. +Default: + +
+None<Key>n: ChangeName(Object)
+
+ + + + + +
`ChangeOctagon(Object|SelectElements|SelectedPins|SelectedVias|Selected)' +
+Toggles what shape the affected pin(s) or via(s) will be drawn when they +are not square. The shape will either be round or octagonal. +Default: + +
+!Ctrl<Key>o: ChangeOctagon(Object)
+
+ + + + + +
`ChangeSize(Object, value)' +
+
`ChangeSize(SelectedLines|SelectedPins|SelectedVias, value)' +
+
`ChangeSize(SelectedPads|SelectedTexts|SelectedNames, value)' +
+
`ChangeSize(SelectedElements, value)' +
+To change the size of an object you have to bind these action to some +X event (or use :ChangeSize(...)). If value begins with +a + or - then the value will be added (or subtracted) from the current +size, otherwise the size is set equal to value. Range checking is +done to insure that none of the maximum/minimums of any size are violated. +If Object is passed then a single object at the cursor location is +changed. If any of the Selected arguments are passed then all selected +and visible objects of that type are changed. If the type being modified is +an element, then the thickness of the silkscreen lines defining the element +is changed. +Default: + +
+None<Key>s:   ChangeSize(Object, +5)
+!Shift<Key>s: ChangeSize(Object, -5)
+
+ + + + + +
`ChangeSquare(Object|SelectedElements|SelectedPins)' +
+Toggles the setting of the square flag. The flag is used to identify a +certain pin, normally the first one, of circuits. It is also used to +make SMD pads have square ends. + +
+None<Key>q:   ChangeSquare(Object)
+
+ + + + +
`Command()' +
+Calling Command() pops up an input line at the bottom of the window +which allows you to enter commands. Including all action commands! +The dialog ends when None<Key>Return +to confirm or None<Key>Escape to abort is entered. +Default: + +
+<Key>colon: Command()
+
+ + + + + + + + +
`Connection(Find)' +
+
`Connection(ResetFoundLinesAndRectangles|ResetPinsViasAndPads|Reset)' +
+The Connection() action is used to mark all connections from one pin, +line or via to others. +The ResetFoundLinesAndRectangles, ResetFoundPinsAndVias and +Reset arguments may be used to reset all marked lines and rectangles, +vias and pins or all of them. The search starts with the pin or via +at the cursor position. All found objects are drawn with the color +defined by the resource connectedColor. +See also, Display(Description|NameOnPCB|Value). +Default: + +
+!Shift<Key>c: Connection(Reset)
+None<Key>f:   Connection(Find)
+!Shift<Key>f: Connection(Reset)
+
+ + + + + +
`DeleteRats(AllRats|SelectedRats)' +
+This routine deletes either all rat-lines in the layout, or only +the selected and visible ones. Non-rat-lines and other layout +objects are unaffected. +Default: + +
+None<Key>e:   DeleteRats(AllRats)
+!Shift<Key>e: DeleteRats(SelectedRats)
+
+ + + + + + + + + + + + + + + +
`Display(Description|NameOnPCB|Value)' +
+
`Display(Toggle45Degree|CycleClip)' +
+
`Display(Grid|ToggleGrid)' +
+
`Display(ToggleRubberBandMode)' +
+
`Display(Center|ClearAndRedraw|Redraw)' +
+
`Display(Pinout|PinOrPadName)' +
+This action routines handles some output related settings. It is +used to center the display around the cursor location and to redraw the +output area optionally after clearing the window. +Centering is done with respect to the grid setting. Displaying the +grid itself may be switched on and off by Grid but only if +the distance between two pixels exceeds 1_DISTANCE pixels. +Pcb is able to handle several labels of an element. One of them +is a description of the functionality (eg resistor), the second should be +a unique identifier (R1) whereas the last one is a value (100k). +The Display() action selects which of the names is displayed. +It also controls which name will be affected by the ChangeName command. +If ToggleGrid is passed, Pcb changes between relative +('rel' in the statusline) and absolute grid (an 'abs' in the statusline). +Relative grid means the pointer position when the command is issued is +used as the grid origin; while (0,0) is used in the absolute grid case. +Passing Pinout displays the pinout of the element at the current +cursor location whereas PinOrPadName toggles displaying of the +pins or pads name under the cursor. If none of them matches but the cursor +is inside of an element, the flags is toggled for all of its pins and pads. +For details about rubberbands see also the details about Mode. +Default: + +
+None<Key>c:  Display(Center)
+None<Key>d:  Display(PinOrPadName)
+!Shift<Key>d: Display(Pinout)
+None<Key>r:  Display(ClearAndRedraw)
+None<Key>.:  Display(Toggle45Degree)
+None<Key>/:  Display(CycleClip)
+
+ + + + +
`DRC()' +
+Initiates design rule checking of the entire layout. Must be repeated +until no errors are found. + + + + +
`EditLayerGroups()' +
+Pops up a dialog box to edit the layergroup setting. The function is also +available from the Objects menu. +There are no defaults. + + + +
`Load(ElementToBuffer|Layout|LayoutToBuffer|Nelist)' +
+This routine pops up a fileselect box to load layout, element data, +or netlist. +The passed filename for layout data is saved and may be reused. +ElementToBuffer and LayoutToBuffer load the data into the +current buffer. +There are no defaults. + + + + +
`MarkCrosshair()' +
+This routine marks the current cursor location with an X, and then +the cursor display shows both absolute position and position relative to +the mark. If a mark is already present, this routine removes it and +stops displaying relative cursor coordinates. +Defaults: + +
+!Ctrl<key>m:	MarkCrosshair()
+
+ + + + +
`Mode(Copy|InsertPoint|Line|Move|None|PasteBuffer|Polygon|Thermal)' +
+
`Mode(Remove|Rectangle|RubberbandMove|Text|Via)' +
+
`Mode(Cycle)' +
+
`Mode(Notify)' +
+
`Mode(Save|Restore)' +
+Switches to a new mode of operation. The active mode is displayed by a thick +line around the matching mode selector button. +Most of the functionality of Pcb is implemented by selecting a mode +and calling Mode(Notify). The arguments Line, Polygon, +Rectangle, Text and Via are used to create the +appropriate object whenever Mode(Notify) is called. Some of them, +such as Polygon, need more than one call for one object to be created. +InsertPoint adds points to existing polygons or lines. +Save and Restore are used to temporarily save the mode, switch +to another one, call Mode(Notify) and restore the saved one. Have +a look at the application resource file for examples. +Copy and Move modes are used to change an object's location and, +optionally, to create a new one. The first call of Mode(Notify) attaches +the object at the pointer location to the crosshair whereas the second +one drops it to the layout. The rubberband version of move performs the +move while overriding the current rubberband mode. +Passing PasteBuffer attaches the contents of the currently selected +buffer to the crosshair. Each call to Mode(Notify) pastes this contents +to the layout. Mode(Cycle) cycles through the modes available in the +mode-button pallete. +Mode(None) switches all modes off. +Default: + +
+<Key>Escape:             Mode(None)
+<Key>space:              Mode(Cycle)
+None<Key>BackSpace:      Mode(Save) Mode(Remove) Mode(Notify) Mode(Restore)

+
+ + + + +
`MovePointer(delta_x, delta_y)' +
+With this function it is possible to move the crosshair cursor by using the +cursor keys. The X server's pointer follows because the necessary +events are generated by Pcb. All movements are performed with respect +to the currently set grid value. +Default: + +
+None<Key>Up:      MovePointer(0, -1)
+!Shift<Key>Up:    MovePointer(0, -10)
+None<Key>Down:    MovePointer(0, 1)
+!Shift<Key>Down:  MovePointer(0, 10)
+None<Key>Right:   MovePointer(1, 0)
+!Shift<Key>Right: MovePointer(10, 0)
+None<Key>Left:    MovePointer(-1, 0)
+!Shift<Key>Left:  MovePointer(-10, 0)
+
+ + + + +
`MoveToCurrentLayer(Object|SelectedObjects)' +
+The function moves a single object at the crosshair location or all selected +objects to the current layer. Elements are not moveable by this function. +They have to be deleted and replaced on the other side. +If a line segment is moved and the movement would result in a loss of +connectivity to another segment then via(s) are automatically added to +maintain the connectivity. + +
+None<Key>m:       MoveToCurrentLayer(Object)
+!Shift<Key>m:     MoveToCurrentLayer(SelectedObjects)
+
+ + + + +
`New()' +
+Clear the current layout and starts a new one after entering its name. +Refer to the resource backup for more information. +No defaults. + + + + + + + + +
`PasteBuffer(AddSelected|Clear|1..5)' +
+
`PasteBuffer(Rotate, 1..3)' +
+
`PasteBuffer(Convert)' +
+This action routine controls and selects the pastebuffer as well as all +cut-and-paste operations. Passing a buffer number selects one in of the +range 1..5. The statusline is updated with the new number. +Rotate performs a number of 90 degree counter clockwise rotations +of the buffer contents. AddSelected as first argument copies all +selected and visible objects into the buffer. Passing Clear removes +all objects from the currently selected buffer. Convert causes +the contents of the buffer (lines, arc, vias) to be converted into an +element definition. Refer to section Pastebuffer +for examples. +Default: + +
+!Ctrl<Key>x:       PasteBuffer(Clear) PasteBuffer(AddSelected)
+                   Mode(PasteBuffer)
+!Shift Ctrl<Key>x: PasteBuffer(Clear) PasteBuffer(AddSelected)
+                   RemoveSelected() Mode(PasteBuffer)
+!Mod1<Key>c:       PasteBuffer(Clear) PasteBuffer(AddSelected)
+!Mod1<key>x:       PasteBuffer(Clear) PasteBuffer(AddSelected)
+		   RemoveSelected()
+!Shift<Key>1:      PasteBuffer(1)
+!Shift<Key>2:      PasteBuffer(2)
+!Shift<Key>3:      PasteBuffer(3)
+!Shift<Key>4:      PasteBuffer(4)
+!Shift<Key>5:      PasteBuffer(5)
+None<Key>F3:       Mode(PasteBuffer)
+
+ + + + + +
`Polygon((Close|PreviousPoint)' +
+Polygons need a special action routine to make life easier. Calling +Polygon(PreviousPoint) resets the newly entered corner to the +previous one. The Undo action will call Polygon(PreviousPoint) +when appropriate to do so. Close creates the final +segment of the polygon. This may fail if clipping to 45 degree +lines is switched on, in which case a warning is issued. +Default: + +
+None<Key>p:             Polygon(Close)
+!Shift<Key>p:           Polygon(Close)
+
+ + + + +
`Print()' +
+Pops up a print control box that lets you select the output +device, scaling and many more options. Each run creates all +files that are supported by the selected device. These are +mask files as well as drilling files, silk screens and so on. The table +shows the filenames for all possible files: + +
+        POSIX (extention)             8.3 filename
+		---------------------------------------------
+		*_componentmask.*             cmsk.*
+		*_componentsilk.*             cslk.*
+		*_soldermask.*                smsk.*
+		*_soldersilk.*                sslk.*
+		*_drill.*                     dril.*
+		*_groundplane.*               gpl.*
+		*_group[1..8].*       [..8].*
+
+ +The output may be sent to a postprocessor by starting the filename with the +pipe ("|") character. Any "%f" in a command is replaced +with the current filename. The function is available from the file menu. +There are no defaults. + + + + +
`Quit()' +
+Quits the application after confirming the operation. +Default: + +
+<Message>WM_PROTOCOLS: Quit()
+
+ + + + +
`Redo()' +
+This routine allows you to recover from the last undo command. +You might want to do this if you thought that undo was going to +revert something other than what it actually did (in case you +are confused about which operations are un-doable), or if you +have been backing up through a long undo list and over-shoot +your stopping point. Any change that is made since the undo +in question will trim the redo list. For example if you add +ten lines, then undo three of them you could use redo to put +them back, but if you move a line on the board before performing +the redo, you will lose the ability to "redo" the three "undone" lines. +Default: + +
+!Shift<Key>r:	Redo()
+
+ + + + +
`RemoveSelected()' +
+This routine removes all visible and selected objects. +There are no defaults. + + + + + +
`Report(Object|DrillReport)' +
+This routine pops up a dialog box describing the various +characteristics of an object (or piece of an object such as a pad or pin) +in the layout at the cursor position, or a report about all of the +drill holes in the layout. +There are no defaults. + + + + +
`RouteStyle(1|2|3|4)' +
+This routine copies the sizes corresponding to the numbered route style +into the active line thicknes, via diameter, and via drill size. +Defaults: + +
+!Ctrl<Key>1: RouteStyle(1)
+...
+!Ctrl<Key>4: RouteStyle(4)
+
+ + + + +
`Save(Layout|LayoutAs)' +
+
`Save(AllConnections|AllUnusedPins|ElementConnections)' +
+Passing Layout saves the layout using the file from which it was +loaded or, if it is a new layout, calls Save(LayoutAs) which queries +the user for a filename. +The values: AllConnections, AllUnusedPins and +ElementConnections start a connection scan and save all connections, +all unused pins or the connections of a single element to a file. +There are no defaults. + + + + +
`Select(All|Block|Connection|ToggleObject)' +
+
`Select(ElementByName|ObjectByName|PadByName|PinByName)' +
+
`Select(TextByName|ViaByName)' +
+Toggles either the selection flag of the object at the crosshair position +(ToggleObject) or selects all visible objects, all inside a +rectangle or all objects which have been found during the last connection +scan. The ByName functions use a regular expression search, +always case insensitive, to select the objects. +Default: + +
+None<Btn3Down>:  Select(ToggleObject)
+None<Btn3Down>,None<Btn3Motion>: See resource file - this is complex
+
+ + + + + + + + +
`SetValue(Grid|LineSize|TextScale|ViaDrillingHole|ViaSize|Zoom, value)' +
+Some internal values may be changed online by this function. +The first parameter specifies which data has to be changed. The other one +determines if the resource is set to the passed value, if value is +specified without sign, or increments/decrements if it is specified with +a plus or minus sign. +The function doesn't change any existing object only the initial values of +new objects. Use the ChangeSize() and ChangeDrillSize() +to change existing objects. +Default: + +
+None<Key>g:        SetValue(Grid, +5)
+!Shift<Key>g:      SetValue(Grid, -5)
+None<Key>l:        SetValue(LineSize, +5)
+!Shift<Key>l:      SetValue(LineSize, -5)
+None<Key>t:        SetValue(TextScale, +10)
+!Shift<Key>t:      SetValue(TextScale, -10)
+None<Key>v:        SetValue(ViaSize, +5)
+!Shift<Key>v:      SetValue(ViaSize, -5)
+!Mod1<Key>v:       SetValue(ViaDrillingHole, +5)
+!Mod1 Shift<Key>v: SetValue(ViaDrillingHole, -5)
+None<Key>z:        SetValue(Zoom, -1)
+!Shift<Key>z:      SetValue(Zoom, +1)
+
+ + + + +
`SwapSides()' +
+This routine changes the board side you are viewing. +Default: + +
+None<Key>Tab:      SwapSides()
+
+ + + + +
`SwitchDrawingLayer(value)' +
+Makes layer numer 1..8 the current one. +Default: + +
+None<Key>1:        SwitchDrawingLayer(1)
+...
+None<Key>8:        SwitchDrawingLayer(8)
+
+ + + + + +
`ToggleHideName(Object|SelectedElements)' +
+Toggles whether the element's name is displayed or hidden. If it +is hidden you won't see it on the screen and it will not appear +on the silk layer when you print the layout. + +
+None<Key>h:	ToggleHideName(Object)
+!Shift<Key>h:	ToggleHideName(SelectedElements)
+
+ + + + +
`Undo()' +
+
`Undo(ClearList)' +
+The unlimited undo feature of Pcb allows you to recover +from most operations that materially affect you work. +Calling Undo() without any parameter recovers +from the last (non-undo) operation. ClearList is used to release the +allocated memory. ClearList is called whenever a new layout is started +or loaded. See also Redo. +Default: + +
+None<Key>u:        Undo()
+!Shift Ctrl<Key>u: Undo(ClearList)
+
+ + + + +
`Unselect(All|Block|Connection)' +
+Unselects all visible objects, all inside a rectangle or all objects which +have been found during the last connection scan. +Default: + +
+!Shift <Btn3Down>: Mode(Save) Mode(None) Unselect(Block)
+!Shift <Btn3Up>:   Unselect(Block) Mode(Restore)
+
+ +
+ +

+ + + + + +

Default Translations

+

+This section covers some default translations of key and button events as +defined in the shipped default application resource file. Most of them have +already been listed in section Actions. Pcb makes use of a nice X11 +feature; calling several action routines for one event. + + +

+ +
`None<Key>BackSpace:' +
+ + + + + +
`None<key>Delete:' +
+
`!Shift<Key>BackSpace:' +
+
`!Shift Ctrl<Btn1Down>:' +
+The object at the cursor location is removed by None<Key>BackSpace or +Shift Ctrl<Btn1Down> whereas Shift<Key>BackSpace also removes +all other objects that are fully-connected to the one at the cursor location. + + +
`!Mod1 Ctrl<Key>Left:' +
+
`!Mod1 Ctrl<Key>Right:' +
+
`!Mod1 Ctrl<Key>Up:' +
+
`!Mod1 Ctrl<Key>Down:' +
+Scroll one page in one of the four directions. + + +
`None<Key>Left:, !Shift<Key>Left:' +
+
`None<Key>Right:, !Shift<Key>Right:' +
+
`None<Key>Up:, !Shift<Key>Up:' +
+
`None<Key>Down:, !Shift<Key>Down:' +
+Move crosshair either one or ten points in grid. + + +
`None<Key>Return:' +
+Finished user input, selects the 'default' button of dialogs. + + +
`None<Key>Escape:' +
+Mode(Reset), aborts user input, selects the 'abort' button of +dialogs or resets all modes. + + + + + + +
`None<Btn2Down>, Btn2<Motion>, None<Btn2Up>:' +
+
`!Mod1<Btn2Down>, Btn2<Motion>, !Mod1<Btn2Up>:' +
+The first sequence moves the object or element name at the cursor location. +The second one copies the objects. Copying isn't available for +element names. + +
+ +

+ + + + +

File Formats

+

+All files used by Pcb are read from the standard output of a command +or written to the standard input of one as plain seven bit ASCII. This +makes it possible to use any editor to change the contents of a layout file. +It is the only way for element or font description files to be created. +To do so you'll need to study the example files `example/*' and +`default_font' which are shipped with Pcb. +For an overview refer to section Introduction. + + +

+ + + + + + +The following sections provide the necessary information about the syntax of +the files. +Netlist files are not created by Pcb, but it does use them. For information +on the format of a netlist file see the :rn, +section User Commands. Rat lines are added on the current layer using the current +The commands described allow you to add almost any additional +functionality you may need. Examples are compressed read and write access as +well as archives. The commands themselves are defined by the resources +elementCommand, fileCommand, fontCommand, +libraryCommand, libraryContentsCommand and saveCommand. +Note that the commands are not saved along with the data. +It is considered an advantage to have the layout file contain all necessary +information, independent of any other files. + + +

+One thing common to all files is they may include comments, newlines, +and carriage returns at any place except within quoted strings. + + + +

+ +

+ + + + + +

Layout File Format

+

+The layout file describes a complete layout including symbols, vias, +elements and layers with lines, rectangles and text. This is the most +complex file of all. + + + +

+File            = Header Font PCBData
+Header          = PCBName [GridData] [CursorData] [PCBFlags] [Groups]
+PCBName         = "PCB(" Name Width Height ")"
+GridData        = "Grid(" Grid GridOffsetX GridOffsetY ")"
+CursorData      = "Cursor(" X Y zoom ")"
+PCBFlags        = "Flags(" Flags ")"
+Groups          = "Groups(" GroupString ")"
+Styles		= "Styles(" StyleString ")"
+Font            = {FontData}...
+FontData        = {Symbol}...
+Symbol          = "Symbol(" SymbolID Spacing ")"
+                      "(" {SymbolData}... ")"
+SymbolData      = {SymbolLine}...
+SymbolLine      = "SymbolLine(" X1 Y1 X2 Y2 Thickness ")"
+PCBData         = {Via | Layer | Element}...
+
+Via             = "Via(" X Y Thickness DrillingHole Name Flags ")"
+
+Element         = "Element(" Flags Description LayoutName Value \
+                      TextX TextY direction scale TextFlags")"
+                      "(" {ElementData}... [Mark] ")"
+ElementData     = {ElementLine | Pad | Pin | ElementArc }...
+ElementArc      = "ElementArc(" X Y Width Height
+                      StartAngle DeltaAngle Thickness ")"
+ElementLine     = "ElementLine(" X1 Y1 X2 Y2 Thickness ")"
+Mark            = "Mark(" X Y ")"
+Pad             = "Pad(" X1 Y1 X2 Y2 Thickness Name PinNumber Flags")"
+Pin             = "Pin(" X Y Thickness DrillingHole Name PinNumber Flags ")"
+
+Layer           = "Layer(" LayerNumber Name ")"
+                      "(" {LayerData}... ")"
+LayerData       = {Line | Polygon | Text}...
+Line            = "Line(" X1 Y1 X2 Y2 Thickness Flags")"
+Arc		= "Arc(" X Y Width Height StartAngle DeltaAngle Thickness Flags")"
+Polygon         = "Polygon(" Flags ")" \
+                      "(" {Points}... ")"
+Points          = "(" X Y ")"
+Text            = "Text(" X Y direction scale TextData Flags")"
+
+ +
+ +
`PCBName' +
+is used to define the layout's name which is independent of its filename. +It is displayed in the lower left corner of the main window. + +
`GridData' +
+is optional and is used to save the grid setting and offset which were set +at the time the layout was saved. + +
`CursorData' +
+also is an optional parameter to save the last cursor location and zoom value. +The real zoom factor is calculated by scale = 1:(2 power value). + +
`PCBFlags' +
+determine how to draw lines and which name of the elements should be +displayed. + +
+    bit 4:  do rubberband moves and rotates if set
+    bit 5:  display description of elements if set
+    bit 6:  display unique name of an element if set
+    bit 7:  use absolute grid if set
+    bit 8:  don't clip lines to 45 degrees
+
+ +
`Groups' +
+Layergroups are saved by using this optional parameter. The only way of +changing them is to use an editor and alter the appropriate line. The +characters c,s idenify the component- and solder-side for SMD +objects. + +
`Symbol' +
+See the description of font files in this chapter. + +
`Via' +
+Vias are always connected to all layers which also means vias are one +logical level ahead of layers. Vias are defined by position, size, name and +by some flags. + +
+    bit 0:  always clear
+    bit 1:  always set
+    bit 2:  set if via was found during a connection search
+    bit 4:  set if via is a hole (has no copper annulus)
+    bit 5:  display the vias name
+    bit 6:  via has been selected
+    bit 12: set if via has octagonal shape
+    Other bits have special meaning and should not be changed
+    by the user.  See const.h for more information
+
+ +
`Element' +
+See the description of element files in this chapter. + +
`Layer' +
+A layer is the central object from the user's point of view. It holds all +connections and all text objects. Up to 8 may be used individually. +Its number, starting with one, and its name are read as arguments. + +
+ +
`Line' +
+All lines are identified by their start and endpoints together with their +thickness and some flags. They have to fit a 45 degree scheme. + +
+    bit 2:  set if line was found during a connection search
+    bit 4:  line is a rat-line
+    bit 6:  line has been selected
+
+ +
`Polygon' +
+used to fill a larger area with `copper'. The coordinates specify the +corners. The flags are: + +
+    bit 2:  set if polygon was found during a connection search
+    bit 4:  polygon is a 1.5 style polygon that automatically clears pins
+    bit 6:  polygon has been selected
+
+ +
`Text' +
+You may use text objects to add information to your board. An example would +be naming a connector or marking pin one of it. The position marks the +lower left corner of the string which is also a fixpoint for rotations. +Text directions are independent to those of lines. They are counted from +zero to three with a meaning of zero to 270 degree rotations counter-clockwise. +The scaling value is a positive integer which determines a zoom factor in +percent. + +
+    bit 6:  the text has been selected
+    bit 7:  the text is on the solder (back) side of the board
+    bit 10: the text is on the silkscreen layer
+
+ +
+ +
+ +

+ + + + + +

Element File Format

+

+Element files are used to describe one component which then may be used +several times within one or more layouts. You will normally split the +file into two parts, one for the pinout and one for the package description. +Using m4 allows you to define pin names as macros in one file and +include a package description file which evaluates the macros. See +the resource elementCommand for more information. The pins (and pads) +must appear in squential order in the element file (new in 1.5) so that +pin 1 must be the first PIN(...) in the file. + + +

+Doing things this way makes it possible to use one package file for several +different circuits. See the sample files `dil*'. + + +

+The lowest x and y coordinates of all subobjects of an element are used +as an attachment point for the crosshair cursor of the main window. + + + +

+File            = {Element}...
+Element         = "Element(" Flags Description LayoutName Value \
+                      TextX TextY direction scale TextFlags")"
+                      "(" {ElementData}... [Mark] ")"
+ElementData     = {ElementLine | Pad | Pin | ElementArc }...
+ElementArc      = "ElementArc(" X Y Width Height
+                      StartAngle DeltaAngle Thickness ")"
+ElementLine     = "ElementLine(" X1 Y1 X2 Y2 Thickness ")"
+Mark            = "Mark(" X Y ")"
+Pad             = "Pad(" X1 Y1 X2 Y2 Thickness Name PinNumber Flags ")"
+Pin             = "Pin(" X Y Thickness DrillingHole Name PinNumber Flags ")"
+
+ +
+ +
`Element' +
+Objects of type element are determined by flags, some names, a canonical +and a layout name as well as a value. Additional fields are text position, +their direction counted from zero to three (n * 90 degrees counter-clockwise) +and element data. + +
+ +
`Flags' +
+The flag field determines the state of an element. +The bit values are: + +
+    bit 4:  the element name is hidden
+    bit 6:  element has been selected
+    bit 7:  element is located on the solder side
+
+ +
`TextFlags' +
+
`scale' +
+
`direction' +
+See the description of text object earlier in this chapter. + +
`ElementLine' +
+A line is defined by its start and end points and by its size, or width. + +
`ElementArc' +
+Defines an arc by its center, width, height, startangle, its length in +degrees and its size. Remember the y axis on the screen grows downwards. + +
`Mark' +
+is just a hint to make positioning easier. The crosshair will be positioned +here. Its center is passed as the two arguments. + +
`Pad' +
+A pad is very similar to a line except it may not be disconnected from +its element and it has an associated name. +Is is defined by two end point position, size, name and by some flags. + +
+    bit 2:  set if pad was found during a connection search
+    bit 5:  display the pads name
+    bit 6:  pad has been selected
+    bit 7:  pad is located on the solder side
+
+ +
`Pin' +
+A pin is very similar to a via except it may not be disconnected from +its element. + +
+    bit 0:  always set
+    bit 1:  always clear
+    bit 2:  set if pin was found during a connection search
+    bit 3:  set if pin is only a mounting hole (no copper annulus)
+    bit 5:  display the pins name
+    bit 6:  pin has been selected
+    bit 8:  pin is drawn as a square
+    bit 12: set if pin is drawn with an octagonal shape
+
+ +
+ +
+ +

+ + + + + +

Font File Format

+

+A number of user defined symbols are called a font. There is only one per +layout. All symbols are made of lines. See the file `default_font' +as an example. + + +

+The lowest x and y coordinates of all lines of a font are transformed to (0,0). + + + +

+File            = Font
+Font            = {FontData}...
+FontData        = {Symbol}...
+Symbol          = "Symbol(" SymbolID FontPosition ")"
+                      "(" {SymbolData}... ")"
+SymbolData      = {SymbolLine}...
+
+ +
+ +
`Symbol' +
+The two arguments are the ASCII code of the symbol and its distance to +the next symbol. Undefined symbols are drawn as filled rectangles. +The ASCII code may be passed as a character constant or as a hexadecimal +value. + +
+ +
`SymbolLine' +
+The symbol data itself is made up of several entries +of type SymbolLine. +
+ +
+ +

+ + + + + +

Library Contents File Format

+

+There is nothing like a special library format. The ones that have been +introduced in 1.4.1 just use some nice (and time consuming) fetures of GNU +m4. The only predefined format is the one of the contents file +which is read during startup. It is made up of two basic line types: + + + +

+menu entry      = "TYPE="name
+contents line   = template":"package":"value":"description
+name            = String
+template        = String
+package         = String
+value           = String
+description     = String
+String          = <anything except ":", "\n" and "\r">
+
+ +

+No leading whitespaces or comments are allowed in this file. If you need +either one, define a command that removes them before loading. Have a look +to the libraryContentsCommand resource. + + +

+The menu entry will appear in the selection menu at the top and of the +library window. + + +

+ + + + + +

Library File Format

+

+This section provides an overview about the existing m4 definitions +of the elements. There are basically two different types of files. One +to define element specific data like the pinout, package and so on, the +other to define the values. For example the static RAM circuits 43256 and +62256 are very similar. They therefore share a common definition in the +macro file but are defined with two different value labels. + + +

+The macro file entry: + +

+define(`Description_43256_dil', `SRAM 32Kx8')
+define(`Param1_43256_dil', 28)
+define(`Param2_43256_dil', 600)
+define(`PinList_43256_dil', ``pin1', `pin2', ...')
+
+ +

+And the list file: + +

+43256_dil:N:43256:62256
+
+ +

+The macro must define a description, the pin list and up to two additional +parameters that are passed to the package definitions. The first one is +the number of pins whereas the second one defines for example the width +of a package. + + +

+It is very important to select a unique identifier for each macro. In +the example this would be 43256_dil which is also the templates name. +It is required by some low-level macros that +Description_, Param1_, Param2_ and PinList_ are prepended. + + +

+The list file uses a syntax: + +

+template:package:value[:more values]
+
+ +

+This means that the shown example will create two element entries with the +sam package and pinout but with different names. + + +

+A number of packages are defined in `common.m4'. Included are: + + + +

+DIL packages with suffix D, DW, J, JD, JG, N, NT, P
+PLCC
+TO3
+generic connectors
+DIN 41.612 connectors
+zick-zack (SD suffix)
+15 pin multiwatt
+
+ +

+If you are going to start your own library please take care about m4 +functions. Be aware of quoting and so on and, most important check your +additional entry by calling the macro: + + + +

+CreateObject(`template', `value', `package suffix')
+
+ +

+If quoting is incorrect an endless loop may occur (broken by a out-of-memory +message). + + +

+The scripts in the `lib' directory handle the creation of libraries +as well as of their contents files. Querying is also supported. + + +

+I know quite well that this description of the library implementation is +not what some out there expect. But in my opinion it's much more useful to +look at the comments and follow the macros step by step. + + + + +

Installation and Troubleshooting

+

+Compiling and installing the package should be straightforward. If any problems +occur, please contact the author (Thomas.Nau@rz.uni-ulm.de) to find +a solution and include it into the next release. + + + +

+ +

+ + + + +

Compiling and Installing

+

+This section covers the steps which are necessary to compile the package. + + + +

+ +

+ + + + + +

Editing config.h

+

+Most X11 related options are automatically covered by imake +which is called from xmkmf. The ones special to Pcb +have to be edited in `config.h'. +In order of appearance: + + +

+ +
`INFOLIBDIR' +
+ + +must be set to the directory where your GNU info files are located. + + +
`/usr/X11R6/lib/X11/pcb' +
+is the path of a directory where the font files will be installed. + + +
`DEFAULTFONT' +
+the name of the default font file. + + +
`DEFAULTLIBRARY' +
+the name of the default library. + + +
`gm4' +
+the name of GNUs m4 version. + + +
`Mod1' +
+If your window manager has already bound Mod1 together with some +function keys you may want to change this setting. This is true for HP-VUE. + + +
`EXTRA_INCLUDES' +
+Some systems do not have the Athena Widget include files in their normal +place as configured by X11s config files. Define this as follows: + +
+    EXTRA_INCLUDES = -I/usr/openwin/share/include
+
+ +This is probably true for Suns which use OpenWindows. + + +
`PATCHES' +
+This symbol is passed to the compiler. Use it to define additional compiler +flags. +Add the -DNEED_STRDUP flag, if your system does not have a strdup() +library function. + + +
`HAS_REGEX' +
+Set to -DHAS_REGEX if your system supports regular expressions. +This enables the actions Select(*ByName). + + + +
`EXITCALL' +
+The symbol EXITCALL should be defined according to the +call on exit functions supported by your system. There are three +choices: + +
+    EXITCALL = -DHAS_ATEXIT    if atexit() is supported (SYSV)
+    EXITCALL = -DHAS_ON_EXIT   if on_exit() and no atexit() is supported
+    EXITCALL =                 if none of them is supported
+
+ +Please check your manpages for details. + + +
`SYS_LIBRARIES' +
+This symbol is used to pass additional libraries to the linker. The only +additional libraries which are used are the math and lex library. + +
+ +

+If you have to make system dependent changes please include them into a +#ifdef Architecture ... #endif construct and mail a copy to +the author (Thomas.Nau@rz.uni-ulm.de). + + +

+Now run xmkmf -a which creates the `Makefiles' and runs +make depend. This should finish without any problems except some +systems which complain about missing include files. Don't worry about any +such warnings at this time, the package should compile without any problems. + + +

+ + + + + + +

Manuals

+

+After xmkmf -a has created the new `Makefile' you are able to +create the manpages, the application resource, the info file, the +TeX output and a reference card by executing + +

+	(cd doc; make)
+	(cd src; make Pcb.ad)
+
+ +

+You'll need TeX, texindex and, if you want PostScript, +dvips to build the manuals. Preformatted documentation for the +default configuration may be found in the `./doc.ps' directory. +A simple make builds everything. +Generate a printed copy to make your life easier. +TeX-3.0 failed, TeX-3.14 worked just fine. + + +

+ + + +

Compiling the Package

+

+After reaching this point, it is time for make. It should build +everything without any errors. +If it doesn't refer to section Troubleshooting. + + +

+You have to be root to install the package or at least a user with +the appropriate priveleges in some X11 directories. Set the umask to +022 or else some files will not be found because the directory isn't +world readable. + + +

+If you do not have the appropriate permissions you should run +`./pcbtest.sh' in the `src' directory to run Pcb from +the installation directory. + + +

+make install and make install.man install the program, +the fonts, the application default resource file, all element and package +data as well as the manpage into the X11 directories. +make install.info does the same for the GNU info file. + + +

+ + + + +

Troubleshooting

+

+There are some known problems. Most of them are related to +missing parts of a standard X11 distribution. Some others are caused by +third party applications such as X servers. To make this list more +complete please mail your problems and, if available, solutions to the author. +The mail address may be found at the beginning of this chapter. +In any case, read section Problems related to X11. + + +

+By the way, you MUST HAVE AN ANSI COMPILER to make Pcb work. + + +

+If the shell script create_sed_script.sh fails with an error +of awk check your system for nawk or get the GNU gawk. +See the script for details. + + +

+Another source of problems are older versions of flex and bison. +Pcb definitely works with flex-2.4.7 and bison-1.22 or +later. The problems will result in a syntax error while parsing files. +You will have to add -lfl to the SYS_LIBRARIES identifier in +`Imakefile'. See also, section FreeBSD and NetBSD. + + +

+The following list gives you just an idea because I'm not able to test +all Pcb releases on all platforms. + + + +

+ +

+ + + + + +

HP Series 700 and 800

+

+You have to install several X11 tools (imake) and include files +or, better, install a complete X11R5 release. Hewlett-Packard doesn't +support the Athena Widgets. So the header files and libraries are missing +from the application media, but they are available as a patch. +They also do not ship the ANSI compiler with the normal operating +system release so you have to buy one or use GCC. +Some of the tools are available as patches. + + +

+In addition, Pcb has been successfully tested on these platforms with +HPUX 9.*, 10.* running self-compiled X11R5. + + +

+ + + + + + +

Sun SPARC architecture

+

+There are no known problems with Sun machines if they use X11R5 instead +of OpenWindows. Pcb compiled successfully with all kinds of +SPARCstations Solaris-2.[345]. + + +

+For problems with OpenWindows refer to section Problems related to X11. + + +

+If xmkmf is missing, try + +

+    /usr/openwin/bin/imake -DUseInstalled -I/usr/openwin/lib/config
+    make Makefile
+    make includes
+    make depend
+
+ +

+instead. I got it compiled but the linker complained about missing symbols. +The problem may be related to the mixed OpenWindows - X11R5 +environment which is installed on the test machine. +Anyway the code was executable and I haven't got a core yet. + + +

+ + + + + +

Silicon Graphics

+

+Pcb has been tested on some boxes running either IRIX-4.0.5 or +IRIX-5.3. The former one uses a X11R4 server. +There are no problems except some additionally needed +compiler flags. For known problems +with X11R4, see section Problems related to X11. Check `Imakefile', too. + + +

+ + + + + +

DEC Alpha

+

+Pcb compiled and runs without problems on DEC UNIX V3.2c if you +do the following instead of calling xmkmf -a: + +

+    xmkmf
+    make Makefiles
+    make includes
+    make depend
+
+ +

+ + + + + +

SCO Unix

+

+John DuBois <spcecdt@deeptht.armory.com> wrote: + +

+SCO-ODT-3.0 requires the latest version of tls003, the Athena
+widget library (available from sosco.sco.com). The main problems
+I have encountered are it core dumps fairly often, especially
+while loading/dropping elements...
+
+ +

+I'll see what I am able to do as soon as I have access to an SCO system. + + +

+ + + + + +

Linux

+

+Since the X11 version of Pcb has been developed on a Linux +system here are no known problems. + + +

+ + + + + +

FreeBSD and NetBSD

+

+If Pcb complains about syntax errors even in the demo files get +rid of your lex and yacc implementation. Replace them by +GNU flex and bison. Don't forget to change the SYS_LIBRARIES +in `Imakefile' from -ll to -lfl. You also need to define: + +

+    YACC = bison -y
+    LEX = flex
+
+ +

+ + + +

Problems related to X11

+

+There are a some problems related to X11R4 or systems derived from +X11 such as OpenWindows. See section Sun SPARC architecture. You at least have to change +all occurances of baseTranslations in the resource files to +translations if you are using a X11R4 server. Look at the +X11R5 Intrinsics manual for details. + + +

+The panner widget (print dialog box) appears only in release X11R5 and +later. It really simplifies adjusting the offsets. +With earlier releases the printout will always appear in the center of the +page. + + +

+You may have some problems in a mixed X11-OpenWindows +environment. +If you want to try it anyway you have to add an additional path for +include files and define another symbol in `Imakefile', + +

+    EXTRA_INCLUDES = -I/usr/openwin/include
+
+ +

+Pcb has been tested successfully with X11R6 under Linux 1.1.59 +and later. + + +

+If your TeX installation complains about a missing `texinfo.tex' +file copy the one included in this release (directory `doc' +to your TeX macro directory. +Note, there are probably newer versions of this file available from some +FTP sites. +TeX-3.0 failed, TeX-3.14 worked just fine. Check our FTP server +ftp.uni-ulm.de for ready-to-print versions of the manuals. + + + + +

See the GNU +General Public License for more details. + + +File: pcb.info, Node: History, Next: Intro, Prev: Copying, Up: Top + +History +******* + + `Pcb' is a handy tool for laying out printed circuit boards. It was +first written for an Atari ST in 1990 and ported to `UNIX' and `X11' in +1994. I never had the intention to create another professional layout +system, but to write a tool which supports people like you who do some +home-developing of hardware. For this reason it has no auto-router nor +auto-placement code. + + The second release 1.2 included menus for the first time. This made +`PCB' easier to use and thus a more important tool. + + Release 1.3 introduced undo for highly-destructive commands, more +straightforward action handling and scalable fonts. Layer-groups were +introduced to group signal-layers together. + + Release 1.4 provided support for add-on device drivers. Two layers +(the solder and the component side) were added to support SMD elements. +The handling of libraries was also improved in 1.4.1. Support for +additional devices like GERBER plotters started in 1.4.4. The undo +feature was expanded and the redo-feature added in 1.4.5. + + Release 1.5 provides support for rats-nest generation from simple net +lists. It also allows for automatic clearances around pins that pierce +a polygon. A variety of other enhancments including a Gerber RS274X +driver and NC drill file generation have also been added. harry eaton +(haceaton@aplcomm.jhuapl.edu) was responsible for most of the changes +found in this release. + + Release 1.6 provides automatic screen updates of changed regions. +This should elliminate most of the need for the redraw (r) key. Also +some changes to what order items under the cursor are selected were +made for better consistancy - it is no longer possible to accidentally +move a line or line point that is completely obscured by a polygon +laying over top of it. Larger objects on the upper most layers can be +selected ahead of smaller objects on lower layers. These changes make +operations more intuitive. A new mode of line creation was added that +creates two line on 45 degree angles with a single click. The actual +outline of the prospective line(s) are now shown during line creation. +An arc creation mode was added. Drawn arcs are quarter circles and can +be useful for high frequency controlled impedance lines. (You can have +eighth circle arc if the source is compiled with -DARC45, but be aware +that the ends of such arcs can never intersect a grid point). Two new +flags for pins and vias were created - one indicates that the pin or +via is purely a drill hole and has no copper annulus. You can only +toggle this flag for vias - for elements, it must be an integral part +of the element definition. The other flag controls whether the pad +will be round or octagonal. There is also now a feature for converting +the contents of a buffer into an element. Vias become the pins (or +mounting holes), lines and arcs on the solder layer become silkscreen, +and lines on the component layer become the pads. Action commands +entered via the colon command entry are no longer proceeded with "a ", +just type the command directly. Several bugs have also been fixed. New +ones were probably introduced since extensive changes were made. harry +eaton was responsible for these changes. + + Release 1.6.1 adds the ability to make groups of action commands +bound to a single X11 event to be undone by a single undo.

This +chapter gives an overview of the object types and their relationship to +each other. For a complete description of how to use `Pcb', refer to +*Note Getting Started::. The layout is generated on-screen on a grid +that has its origin in the upper left corner of the screen. The x +coordinate increases to the right, y increases down to the bottom. All +distances and sizes in `Pcb' are measured in mils (0.001 inch). One +unit on the display grid is one mil in distance on the board. The +sections in this chapter are sorted by the order of appearance of the +objects within a layout file. + +* Menu: + +* Symbol Objects:: Information about fonts and symbols. +* Via Objects:: Vias and pins connect layers. +* Element Objects:: Element, the basic type of circuits. +* Layer Objects:: A `container' for lines, text... +* Line Objects:: +* Arc Objects:: +* Polygon Objects:: +* Text Objects:: Objects to add symbols to your board. + + +File: pcb.info, Node: Symbol Objects, Next: Via Objects, Up: Intro + +Symbols +======= + + The top object is the layout itself. It uses a set of symbols that +resides at the first logical level. Each symbol is uniquely identified +by a seven bit `ASCII' code. All layout objects share the same set of +symbols. These symbols are used to form text objects on the silkscreen +and copper layers. Undefined symbols are drawn as filled rectangles. + + Every font file is preprocessed by a user-defined command when it is +loaded. For details see `fontCommand', *Note Resources::. + + +File: pcb.info, Node: Via Objects, Next: Element Objects, Prev: Symbol Objects, Up: Intro + +Vias +==== + + Vias are identical to the pins used by elements except that they can +be added or removed individually. The purpose of vias is to provide +connections between different layers. Don't use vias for adding +elements to the layout, even if that seems easier than creating a new +element. Vias are useful for defining arbitrary drill points such as +those used for mounting a board. You can assign a name to a via even +though you probably won't ever want to. Vias reside at the first +logical level; therefore, each via exists on all layers. (*i.e.* blind +vias are not supported) + + +File: pcb.info, Node: Element Objects, Next: Layer Objects, Prev: Via Objects, Up: Intro + +Elements +======== + + Elements represent the components on a board. Elements are loaded +from `ASCII' coded files in a similar manner to the layout file itself. +They are composed of lines and arcs on the silk-screen layer (used to +define the package outline) , pins (or pads for SMD) and three labels +that define the description, the element's layout-name (which also +appears on the silk- screen layer) and its value. Element pins are +contained on the first logical level and so reside on all layers. A +mark is used to position the element with respect to the cursor +cross-hair during pasting. SMD elements use pads instead of pins. +Pads are handled similarly to lines on a layer but they must be oriented +either vertically or horizontally. Pads can have either rounded or +square ends. All parts of an element are treated as one unit. It is +not possible to delete a single pin or break an element into pieces on +the layout. You can resize separate pieces of an element, but doing so +is usually a bad idea. + + Elements are supported by several special layers: *silk*, +*pins/pads* and *far-side*. The *silk* layer shows the package outline +and also holds legend text and element names. The *pins/pads* layer is +used to toggle whether the element's pins and pads are displayed. The +*far-side* layer controls visibility of objects (silkscreen and pads) +that are on the far (*i.e.* not currently viewed) side of the board. + + Every element file is preprocessed by a user-defined command when +the file is read. For details see `elementCommand', *Note Resources::. +`m4', the default value of `elementCommand', allows you to create +libraries for package definitions that are shared by all elements. The +element libraries distributed with `Pcb' expect `m4' or an equivalent +to be the *elementCommand*. + + `Pcb' can create a list of all connections from one (or all) +elements to the others or a list of unconnected pins. It can also +verify the layout connections against a netlist file. The element's +`layout-name' is the name used to identify an element in a netlist file. +The pin numbering for an element is defined by unique strings assigned +to each pin. In addition to the "pin number" string, each pin has a +"name" which describes its function. Previously element pin number was +established by the order of appearance of the pin definitions in the +layout or element file. Since the "number" strings for each pin are a +new feature, if they are absent then the numbering is again established +by the order of pin appearance in the file. In other words, the first +pin appearing in the file is pin one, the next pin is pin two and so on. +Usually the names assigned to pins are simply numbers, but they don't +have to be. It is only necessary that the "number" string for the pin +matches exactly the "number" string in the netlist file. Be aware that +a few of the library parts may still be incorrectly implemented +regarding pin-numbering. All of the DIL (Dual- Inline-Pins) parts are +correct and most of the others are too, but you should verify the pin +numbering of any non-DIL part (use the *Report Menu* to see what `Pcb' +thinks a pin's number is) before using the rats nest feature with a +library part. Hopefully sometime soon someone will volunteer to +cross-check all of the element libraries and make fixes available as +necessary. `Pcb' can also check a layout to see that it meets minimum +spacing and overlap rules. + + You can make your own quick-and-dirty element definitions +graphically now. Simply draw vias for the pins and lines and arcs on a +solder layer for the silkscreen outline. You should name each via with +the pin number. If you want to create a SMD device, draw lines for the +pads on a component side layer (You must draw these in pin number order +since lines can't be named). They must be either horizontal or vertical +or they will not be recognized as pads. Once you are happy with the +geometry, select everything that is to become part of the element, then +choose "cut to buffer" from the menu. Now select "convert buffer to +element" from the menu. Viola'! Afterwards you can make pin one +square (or pads) if you like, and give the element its various names. +Note that the element mark corresponds to the cut position when +everything was put into the buffer. If the vias are not named, then the +pin numbering will correspond to the order in which the vias were +placed. + + +File: pcb.info, Node: Layer Objects, Next: Line Objects, Prev: Element Objects, Up: Intro + +Layers +====== + + Every layout consists of several layers that can be used +independently or treated as a group. Layer groups can be used to +logically separate (and color-code) different traces (*e.g.* power and +signal); however, all layers within a group reside on the same physical +copper layer of a board, so using different layers within the same +group won't provide electrical separation where they touch or overlap. +For details, see `layerGroups', *Note Resources::. Each layer is drawn +in a color defined in the resource file (for details see `layerColor', +*Note Resources::) and identified by a name that you can change. +Layers are really just containers for line, polygon, and text objects. +The component and solder layers contain SMD elements as well, but the +file structure doesn't reflect that fact directly. Each layer group +represents a physical layer on the printed circuit board. If you want +to make a four layer board, you'll need to have four layer groups. +Connections between layer groups are established only through element +pins and vias. The relationship between a specific layer and the board +itself is configureable from the `Edit layer groups' option in the +`Objects' menu. The layer groups corresponding to the physical layers +*component-side* and *solder-side* are always defined, and you must map +at least one logical layer to each. Of course, you are not obligated +to put tracks on either of them. SMD-elements always reside on either +the component-side or the solder-side layer group. You can swap which +side of the board you are viewing by pressing *Tab*. You can +decide which layer group will be the solder side and which will be the +component side. The layers groups just have a name or number +associated with them - where they are sandwiched in the board is left +to the manufacturing processes. + + +File: pcb.info, Node: Line Objects, Next: Arc Objects, Prev: Layer Objects, Up: Intro + +Lines +===== + + Lines are used to draw tracks on the pc board. When in the line +mode, each ** press establishes one end of a line. Once the +second point is defined, the line is drawn and a new line started where +the first one ended. You can abondon the new starting point in favor +of another by pressing *Ctrl*. The undo function (*u*) will +take you back point by point if you use it while in the line mode. New +lines can be restricted to 45 degree angles if desired. You can toggle +this restriction on and off while creating lines by pressing *.* +(that is the *period* key). If the 45 degree restriction is turned on, +then the */* can be used to cylce through three different modes of +45 degree line creation. One mode just creates a single line forced to +the nearest 45 degree vector. The next mode creates two lines from the +start to end points such that the first line leaves the start point at +a 90 degree vector, and the second line enters the end point on a 45 +degree vector. The next mode creates two lines such that the first line +leaves the start point on a 45 degree vector and arrives at the end +point on a 90 degree vector. You can temporarily swap between the last +two modes by holding the shift key down. It is simple to edit a line +type object by breaking it into pieces (insert point mode), moving an +end point (or the whole line) (**), or changing +the layer it resides on (*m* moves the line under the pointer to +the active layer). In the case when two line segments meet at exactly +the same point you can delete the intermediate point, otherwise the +delete mode removes an entire line. Feel free to experiment since +`Pcb' will allow you to undo anything that materially affects your work. +If you switch active layers in the midst of placing lines a via will +automatically be placed, when necessary, in order to continue the +connection. + + +File: pcb.info, Node: Arc Objects, Next: Polygon Objects, Prev: Line Objects, Up: Into + +Arcs +==== + + With version 1.6 it is possible to draw copper arcs. The arcs are +restricted to be quarter circles. This means they always bend a right +angle. They are very similar to lines otherwise. They are created on +the current layer and have the same thickness that new lines will have. +The various clicks for creating lines work pretty much the same way +for creating arcs. The start point for the arc is at the first ** +position. In order to make the arc curve in the direction desired, +drag the mouse along the tangent line from the starting position +towards the end position. If the grid is too coarse, it may not be +possible to distinguish whether you've moved over then up, or up then +over, so if you can't seem to make the arc go the direction you want, +you should decrease the grid spacing. Alternatively you could drawn +the wrong arc, then rotate and move it where you want. Like the line +tool, after an arc is drawn a new starting point is established at the +end point. Whenever a start point is established by either the line or +arc tools it will be retained if you switch directly between the tools +(e.g. *F2* for Lines, *F8* for Arcs. Of course connection +searches, undo and all the other features you'd expect work with arcs +now. + + +File: pcb.info, Node: Polygon Objects, Next: Text Objects, Prev: Arc Objects, Up: Intro + +Polygons +======== + + Sometimes it's useful to fill large areas with solid copper. The +way to do this is with polygons. Polygons can be created in either the +polygon mode or the rectangle mode. In the polygon mode, you'll have +to define each corner of the polygon with a mouse click (**). +When the last point is clicked exactly on top of the starting point, +the polygon is finished. Since this can be hard to do, the +*Shiftp* will enter the final point for you, closing the polygon. +If the 45 degree angle restriction is turned on and you try to close +the polygon when it is not possible, you'll get a warning instead. If +you haven't finished entering a polygon, but want to undo one (or more) +of the points that you've already defined, use the undo command +(*u*). With the rectangle tool, defining the two opposite corners +is sufficient, but of course the resulting polygon is a rectangle. +Like lines, a polygon can by edited by deleting, inserting and moving +the points that define it. `Pcb' is capable of handling complex +polygons, but using a number of simpler ones improves performance of +the connection tracing code. + + A new feature in version 1.5 of `Pcb' automatically creates clearance +regions around pins and vias that pierce a polygon. This means that they +aren't electrically connected to the polygon unless you add "thermals" +to cross the clearance region. Thermals can be added and removed by +selecting the thermal mode and clicking ** on the pin or via. +Remember that this only creates connections to the polygon on the +active layer. The great advantage to this new polygon behavior is that +simple or complex ground and/or power planes can be easily made with +polygons and seen on the screen. If you don't want this auto-clearance +behavior, or you load a layout created by an earlier version of `Pcb', +the old behavior (shorts to all piercing pins and vias) is available. +A `ChangeSize' operation (*s*) toggles a polygon between the new +and old polygon/pin behavior. + + +File: pcb.info, Node: Text Objects, Prev: Polygon Objects, Up: Intro + +Text +==== + + Text objects should be used to label a layout or to put additional +information on the board, but not to identify elements because elements +have their own labels. Text is always horizontal when first created, +but the rotate mode can align it along 0, 90, 180 and 270 degree angles. +Text can be moved from any layer to the silk-screen layer with a +command in the `selection menu'. Text that is moved to the silk-screen +layer will appear on the solder-side silk-screen if it originating on a +solder-side layer. Otherwise moving it to the silk-screen layer will +put it on the component-side silk-screen. To move text back to a +copper layer from the silk-screen, use the `MoveToCurrentLayer' +(*m*) command. Text on the far side of the board will +automatically appear mirror-imaged. + + TEXT OBJECTS ON A COPPER LAYER CREATE COPPER LINES BUT THEY ARE NOT +SCANNED FOR CONNECTIONS OR TESTED FOR CREATING SHORTS VS. THE NETLIST. +NEITHER ARE TEXT OBJECTS TESTED AGAINST ANY DESIGN RULES. + + +File: pcb.info, Node: Getting Started, Next: User Commands, Prev: Intro, Up: Top + +Getting Started +*************** + + The goal of this chapter is to give you enough information to learn +how `Pcb' works and how to develop your layouts to make the best use of +`Pcb''s features. All event translations (*i.e.* the buttons and keys +you press) refer to the default application resource file shipped with +`Pcb'. There is probably no need to change them unless your window +manager uses some of the button events itself; however, if you *want* +to customize the behavior of `Pcb' then changing the resource file is +usually the best way to do it. + + Get yourself a printout of this chapter and *User Commands*, if you +haven't already done so, and follow the examples. An example layout +may be found in `example/68HC11'. An example illustrating some version +1.5 features is found in `example/LED' along with its corresponding +netlist file `example/LED.NET'. + + Start `Pcb' (the actual command will use all lower-case letters) +without any additional options. If you get the error message: + + can't find default font-symbol-file 'default_font' + + then the font searchpath or filename in the application resource + file is wrong. Be sure that your `m4' program supports searchpaths. +If not, get `GNU m4'.

When +a selected menu operation requires an additional button click, the +status-line is replaced by a message telling you to position the cursor +and click. When a text input is required, the status-line is replaced +by the Input-field which has a prompt for the typed input. + + The status-line shows, from left to right, the side of the board +that you are viewing (*Tab* changes this), if an absolute (abs) or +relative (rel) grid is used, if new lines are restricted to 45 degrees, +which type of 45 degree line mode is active, whether rubberband move and +rotate mode is on (R), the current grid values, and the zoom factor. +This information is followed by the line-width, via-size and drilling +hole in mil, text scaling, the active buffer number and the name of the +layout. An asterisk appearing at the left edge indicates the layout has +been modified since the last save. Note that the name of the layout is +not the same thing as the filename of the layout. + + The input-field pops up (temporarily replacing the status-line) +whenever user input is required. Two keys are bound to the input field: +*Escape* aborts the input, *Return* finishes it. + + The present cursor position is displayed in the upper right corner +of the window. Normally this position is an absolute coordinate, but +with version 1.5 of `Pcb' you can anchor a marker at the current cursor +location by pressing *Ctrlm* then the display will read both the +absolute cursor position as well as the difference between it and the +marker. Pressing *Ctrlm* again turns the marker off. + + +File: pcb.info, Node: Control Panel, Next: Mode Selectors, Prev: Status-line and Input-field, Up: Application Window + +The Control Panel +----------------- + + The control panel, located at the left side of the window, is used +to turn on and off the display of layer groups and to select the active +drawing layer. If a layer hasn't been named, the label "*(unknown)*" +is used as the defualt. + + The upper control box is used to switch layers on and off. Click +** on one or more of them. Each click toggles the setting. +The currently active layer can't be switched off. The layout is +refreshed when the pointer reenters the drawing area. This prevents +excessive redrawing when the visibility of several layers is changed. +When the layers are grouped, clicking on these fields will toggle the +visibility of all layers in the same group. This is a good idea because +layers in the same group reside on the same physical layer of the +actual board. Use the `Edit layer groups' option in the `Objects' menu +to change the layer groupings. Grouping layers is only useful for +helping you to color-code signals in your layout. Note that grouping +layers actually reduces the number of different physical layers +available for your board, thus to make an eight layer board, you cannot +group any layers. + + *far side* turns on and off the visibility of elements (including +SMD pads) on the opposite board side, as well as silk screening on that +side. It does not automatically hide the x-ray view of the other copper +layers, these must be turned off separately if desired. Use the *tab* +key to view the entire board from the other side. To see a view of +what the back side of the board will actually look like, make the +solder layer the active layer then press *tab* until the status line +says "solder" on the right, then turn off the visibility of all other +layers except pins/pads, vias, and silk. + + The lower control menu, named *active*, is used to change the active +drawing layer. ** pops up a menu to select a one. Each entry +is labeled with the layer's name and drawn in its color. The new +drawing layer is automatically made visible. Try changing the active +layer's name to *ABC* by selecting `set name of layer' from the `File' +menu. Changing the active layer also is available with *1..8*. + + +File: pcb.info, Node: Mode Selectors, Next: Drawing Area, Prev: Control Panel, Up: Application Window + +The Mode Selectors +------------------ + + The mode selector buttons reside below the control panel. They are +used to select the operation mode of `Pcb'. A mode can be thought of as +a tool that gets used when ** is pressed. Each mode causes the +cursor to take on a unique shape that identifies the tool. The buttons +themselves are icons that illustrate their function. The drawing modes +can also be selected from the keyboard: + *Escape* reset mode + *F1* via-mode + *F2* line-mode + *F3* pastebuffer-mode + *F4* rectangle-mode + *F5* text-mode + *F6* polygon-mode + *Insert* insert-point-mode + *F7* thermal-mode + *F8* arc-mode + The *Space* cycles through all of the modes in the mode button +palette. + + Reset-mode is really no mode, and ** has no effect with this +setting. Some of the modes are very simple, such as the via-mode. +Clicking ** while in this mode creates a via at the cross-hair +position. The pastebuffer-mode is similar. With this mode, ** +copies the contents of the active buffer to the layout, but only those +parts that reside on visible layers are copied. The rotate-mode allows +you to rotate elements and text objects 90 degrees counter-clockwise +with each click. The line-mode is explained in detail in *Note Line +Objects::. The arc-mode is explained in detainl in *Note Arc Objects::. +Rectangle-mode, polygon-mode and thermal-mode are explained in detail in +*Note Polygon Objects::. Remember that the thermal-mode will only +create and destroy thermals to polygons on the active layer. + + The insert-point-mode is an editing tool that allows you to add +points into lines or polygons. With version 1.5 of `Pcb', the +insert-point-mode enforces the 45 degree line rule. You can force only +the shorter line segment to 45 degrees by holding the shift key down +while inserting the point. The delete-mode deletes the smallest object +beneath the cursor with each ** click. If you use click at an +end-point that two lines have in common, it will replace the two lines +with a single line spanning the two remaining points. This can be used +to delete an "inserted" point in a line, restoring the previous line. + + +File: pcb.info, Node: Drawing Area, Next: Menu, Prev: Mode Selectors, Up: Application Window + +Drawing Area +------------ + + The drawing area is made from a viewport widget that also includes +two scrollbars. The cursor changes shape depending on the current +operation mode when the pointer is moved into the drawing area. A +crosshair follows the X11 pointer with respect to the grid setting. +Move around and watch the cursor position displayed in the upper right +of the window. Now select a new grid from the *Display* menu. The new +value is updated in the statusline. Now move again and watch the +difference. A different way to change the grid is *Shiftg* to +decrease or *g* to increase it. The grid setting is saved along +with the data when you save a pcb layout. For homemade layouts a value +around 50 is a good setting. The cursor also may be moved with the +cursor keys or, for larger distances, by pressing the *shift* modifier +together with a cursor key. + + +File: pcb.info, Node: Menu, Prev: Drawing Area, Up: Application Window + +Menu +---- + + The menus are located at the top of the drawing area. Most, but not +all, of their functions are also available from the keyboard. Some of +the entries such as *center* require a certain cursor position. In +this case a statusline will popup at the bottom with wording similar to +the following: + move pointer to the appropriate screen position and press a button + Any mouse button will do the job, whereas any key except the cursor +keys will cancel the operation. For details see *Note Actions::. + +`About' + There is no menu hiding behind this button, but a small + information box will pop up. + +`File' + This menu offers a choice of loading, saving and printing data, + saving connection information to a file or quitting the + application. You also may change the layout's or the active + layer's name. Selecting *print layout* pops up a printer control + dialog which is, hopefully, self explaining. This box contains a + panner widget (only `X11R5' and later) which simplifies adjusting + the offsets. With earlier releases the printout will always appear + in the upper left corner with respect to the media margins. + + A selection of several device drivers is available from the + printer control dialog. Presently *PostScript*, *encapsulated + PostScript*, and *GerberX* are supported. *GerberD* support may be + forthcoming. It requires a rastering engine that pcb presently + lacks. + +`Display' + The display menu supports the most needed functions related to + screen output. The entries are used to change the grid to some + popular values, the zoom factor, the displayed element name and + also are used to center or refresh the output. You also may + switch grid-displaying on or off and select between absolute grid + (origin at (0,0)) or relative grid (origin at the position where + the grid has been changed). The relative grid position is now + established at the actual pointer position, NOT necessarily the + same as the crosshair position. This allows you to shift the grid + without changing the grid spacing. I recommend that you zoom in + as close as possible before setting a relative grid so that you're + sure the grid lines fall where you want. The clipping to + 45-degree lines is selected in this menu, as well as enabling + rubberband mode (see description of *Mode*). + +`Sizes' + This menu allows you to select a group of line thickness, via + diameter and via drill size (collectively called a "routing + style") to be coppied to the "active" sizes. You can also change + the names given to these styles and adjust their values from this + menu. You can also edit the "active" sizes (the initial size of + new vias, drilling holes, lines, text-objects and the current + maximum size of the layout) from this menu. + +`Objects' + Displaying the pinout of an element and changing its names, the one + that is currently selected by the *Display* menu, as well as + editing a text object is offered by this menu. The latter two + selections require an additional pointer button click at the + object's position. A dialog for changing the layer groupings is + also reached from this menu. + +`Selection' + This menu covers most of the operations that work with selected + objects. You may either (un)select all visible objects of a + layout or only the ones which have been found by the last + connection scan. The mouse can also be used to change which things + are and are not selected: toggle the selection of a single object + by pressing ** and releasing without moving the mouse. + Pressing *Mod1*, moving and releasing the button selects + all visible objects inside the rectangle. Pressing the modifier + key *Shift* too, unselects all objects in the area. You can delete + all selected objects from this menu, and also move selected text + objects to the silk-screen layer. The other entries change the + sizes of visible and selected objects. + +`Buffer' + This menu handles pastebuffer related actions. You may select one + out of five (per viewing side) buffers to use, rotate or clear its + contents and paste it to the layout. You can also gather objects + in the buffer into an element definition from this menu. Note: + only visible objects are pasted to the layout. + +`Connections' + The entries available through the connections menu button allow + the user to find connections from pins or vias and to manipulate + these. The connection lists may be saved by selecting entries + from the *File* menu. In many cases it is desireable to use the + ratsnest function to check connections against a netlist file + instead of using the connections menu to generate text connection + lists. + +`Undo' + This menu is a frontend for managing the reversing of operations + such as remove, copy, move, name changes, etc. The number of + operations is unlimited (depending on memory). The list is cleared + if new layout data is loaded or by selecting the appropriate entry + from this menu. The inverse operation, redo, is also available. + +`Report' + This menu allows you to generate a dialog that summerizes + information about an object such as sizes and coordinates. You can + also get a report about all of the drills that are used on the + board. + + +File: pcb.info, Node: Log Window, Next: Library Window, Prev: Application Window, Up: Getting Started + +Log Window +========== + + This optional window is used to display all kind of messages +including the ones written to *stderr* by external commands. The main +advantage is that its contents are saved in a scrolling list until the +program exits. Disabling this feature by setting the resource +*useLogWindow* to *false* will generate popup windows to display +messages. The *stderr* of external commands will appear on `Pcb's +*stderr* which normally is the parent shell. I suggest you iconify the +window after startup for example by setting **log.iconic* to *true*. If +*raiseLogWindow* is set *true*, the window will deiconify and raise +itself whenever new messages are to be displayed. + + +File: pcb.info, Node: Library Window, Next: Drawing and Removing, Prev: Log Window, Up: Getting Started + +Library Window +============== + + First appearing in 1.4.1 the library window is one of the best new +features in my opinion. It simplifies loading circuits quiet a lot just +by selecting the appropriate type from the menu at the top. A circuit +is then selected by simply double-clicking on the text line. For +details on libraries check-out *Note Library File:: and *Note Library +Contents File::. + + +File: pcb.info, Node: Drawing and Removing, Next: Moving and Copying, Prev: Library Window, Up: Getting Started + +Drawing and Removing Basic Objects +================================== + + There are several ways of creating new objects: you may draw them +yourself, you may copy an existing object or you may load an element +from a file or library. Creating new objects is normally related to a +special mode depending on the object type. The notation of key and +button events is the same as described in the X11 Intrinsics manual. + + The operation mode may be selected by one of the mode selectors in +the bottom left corner, by one of the function keys listed earlier in +this chapter, or by pressing the space bar to cycle through the modes. +** sends a notify request to the application which responds +by creating or changing the appropriate object or at least takes the +first step to do so. Switching to a mode causes the cursor to take on a +unique shape and also causes the cooresponding mode selector button to +be drawn with thick lines. You can use either cue to see which mode is +currently selected. + + Removing objects is possible using *BackSpace* (or *Delete* +on some machines) which deletes the object at the cursor location. If +more than one object is located at the same position, the smallest +matching type will be chosen. If two or more of the same type are the +smallest at the position, then the newest one will be deleted. You +also may change to *remove-mode* and click ** at the location +of the objects which are to be removed. If you "remove" the end-point +where two lines connect, it will remove the point of connection leaving +a single line that spans the far end points. + + Rotating works in a similar fashion. Change the mode and press +** at the object's location. Remember only text, elements and +arcs can be rotated. (Anything including groups of objects may be +rotated inside a buffer using the rotate buffer menu option.) + + Insert mode provides the capability of inserting new points into +existing polygons or lines. The 45 degree line clipping is now enforced +when selected. Press and hold the shift key while positioning the new +point to only clip the line segment to the nearer of the two existing +points to 45 degrees. You can also toggle the 45-degree clipping in +the middle of a point insertion by pressing the *.* If the shift +key is not depressed and the 45 degree line clipping mode is on, both +new line segments must be on 45 degree angles - greatly restricting +where the new point may be placed. In some cases this can cause +confusion as to whether an insertion has been started since the two new +lines may be forced to lie parallel on top of the original line until +the pointer is moved far from the end points. + + Removing objects, changing their size or moving them only applies to +objects that are visible when the command is executed. + +* Menu: + +* Common:: Keystrokes common to some objects. +* Lines:: +* Arcs:: +* Polygons:: Drawing polygons and rectangles. +* Text:: +* Vias:: +* Elements:: +* Pastebuffer:: A multi-purpose buffer. + + +File: pcb.info, Node: Common, Next: Lines, Up: Drawing and Removing + + There are several keystrokes and button events refering to an +*object* without identifying its type. Here's a list of them: + + ** creates (or deletes) an object depending on the +current mode. + + *BackSpace* or *Delete* removes the visible object at the +cursor location. When more than one object exists at the location, the +order of removal is: via, line, text, polygon and element. The drawn +layer order also affects the search - whatever is top - most (except +elements) is affected before lower items. Basically all this means +that what is removed is probably just what you expect. If for some +reason it isn't, undo and try again. Only one object is removed for +each keystroke. If two or more of the same type match, the newest one +is removed. + + Use *s* and *Shifts* to change the size (width) of lines, +arcs, text objects, pins, pads and vias, or to toggle the style of +polygons (whether pins and vias automatically have clearances). + + *n* changes the name of pins, pads, vias, the string of a text +object, or the currently displayed label of an element. + + *m* moves the line, arc, or polygon under the crosshair to the +active layer if it wasn't on that layer already. + + *u* (undo) recovers from an unlimited number of operations such +as creating, removing, moving, copying, selecting etc. It works like +you'd expect even if you're in the midst of creating something. + + *Shiftr* restores the last undone operation provided no other +changes have been made since the undo was performed. + + *tab* changes the board side you are viewing. + + For a complete list of keystrokes and button events see *Note +Translations::. + + +File: pcb.info, Node: Lines, Next: Arcs, Prev: Common, Up: Drawing and Removing + +Lines +----- + + To draw new lines you have to be in *line-mode*. Get there either by +selecting it from the *Tool palette* or by pressing *F2*. Each +successive *notify* event creates a new line. The adjustment to 45 +degree lines is done automatically if it is selected from the *Display* +menu. You can toggle the 45 degree mode setting by pressing the +*.* (That is the period key). When 45 degree enforcement is turned +on there are three distinct modes of line creation: a single line on +the closest 45 degree vector towards the crosshair (but not necessarily +actually ending at the crosshair), two lines created such that the +first leaves the start point on a 90 degree vector and the second +arrives at the crosshair on a 45 degree vector, and finally two lines +created such that the first leaves the start point on a 45 degree +vector and the second arrives at the crosshair on a 90 degree vector. +These last two modes always connect all the way from the start and end +points, and all lines have angles in 45 degree multiples. The */* +cycles through the three modes. The status line shows a text icon to +indicate which of the modes is active and the lines following the +crosshair motion show the outline of the line(s) that will actually be +created. Press *Escape* to leave line-mode. + + *l*, *Shiftl* and the entries in the *Sizes* menu change +the initial width of new lines. This width is also displayed in the +status line. + + +File: pcb.info, Node: Arcs, Next: Polygons, Prev: Lines, Up: Drawing and Removing + +Arcs +---- + + An Arc is drawn with the *arc-tool*. Get there either by selecting +it from the *Tool palette* or by pressing *F8*. Press *Btn1* to +define the starting point for the arc. Drag the mouse towards the +desired end point along the path you want the arc to follow. The +outline of the arc that will be created is shown on the screen as you +move the mouse. Arcs are always forced to be 90 degrees and have +symmetrical length and width ( i.e. they are a quarter circle). The +next *Btn1* click creates the arc. It will have the same width as new +lines (displayed in the status line) and appear on the active layer. +The arc leaves the starting point towards the crosshair along the axis +whose distance from the crosshair is largest. Normally this means that +if you drag along the path you want the arc to follow, you'll get what +you want. If the grid is set to the arc radius, then the two distances +will be equal and you won't be able to get all of the possible +directions. If this is thwarting your desires, reduce the grid spacing +(*!ShiftG*) and try again. + + +File: pcb.info, Node: Polygons, Next: Text, Prev: Arcs, Up: Drawing and Removing + +Polygons and Rectangles +----------------------- + + A polygon is drawn by defining all of its segments as a series of +consecutive line segments. If the first point matches a new one and if +the number of points is greater than two, then the polygon is closed. +Since matching up with the first point may be difficult, you may use +*Shiftp* to close the polygon. The *Shiftp* won't work if +clipping to 45 degree lines is selected and the final segment cannot +match this condition. I suggest you create simple convex polygons in +order to avoid a strong negative impact on the performance of the +connection scanning routines. The *rectangle-mode* is just an easy way +to generate rectangular polygons. *Polygon-mode* also is selected by +*F6* whereas *rectangle-mode* uses *F4*. Pressing a +** at two locations creates a rectangle by defining two of +its corners. *Insert* brings you to *insert-point-mode* which +lets you add additional points to an already existing polygon. Single +points may be removed by moving the crosshair to them and selecting one +of the delete actions *(remove-mode, BackSpace, or Delete*. This only +works if the remaining polygon will still have three or more corners. +Pressing *u* or *p* while entering a new polygon brings you +back to the previous corner. Removing a point does not force clipping +to 45 degree angles (because it's not generally possible). Newly +created polygons will not connect to pins or vias that pierce it unless +you create a thermal (using the thermal mode) to make the connection. +If the edge of a polygon gets too close to a pin or via that lies +outside of it, a warning will be issued and the pin will be given a +special color. Increasing the distance between them will remove the +warning color. + + +File: pcb.info, Node: Text, Next: Vias, Prev: Polygons, Up: Drawing and Removing + +Text +---- + + Pressing *F5* or clicking one of the text selector buttons +changes to *text-mode*. Each successive notify event (**) +pops up the input line at the bottom and queries for a string. Enter +it and press *Return* to confirm or *Escape* to abort. The +text object is created with its upper left corner at the current pointer +location. The initial scaling is changed by *t* and *Shiftt* +or from the *Sizes* menu. + + Now switch to *rotate-mode* and press ** at the +text-objects location. Text objects on the solder side of the layout +are automatically mirrored and flipped so that they are seen correctly +when viewing the solder-side. + + Use *n* to edit the string. + + TEXT OBJECTS ON COPPER LAYERS CREATE COPPER LINES BUT THEY ARE NOT +SCANNED FOR CONNECTIONS. If they are moved to the silkscreen layer, they +no longer create copper. + + +File: pcb.info, Node: Vias, Next: Elements, Prev: Text, Up: Drawing and Removing + +Vias +---- + + The initial size of new vias may be changed by *v* and +*Shiftv* or by selecting the appropriate entry from the *Sizes* +menu. *Mod1v* and *Mod1 Shiftv* do the same for the drilling +hole of the via. The statusline is updated with the new values. +Creating a via is similar to the other objects. Switch to *via-mode* by +using either the selector button or *F1* then press *]* or +** to create one. *n* changes the name of a via. If you +want to create a mounting hole for your board, then you can place a via +where you want the hole to be then convert the via into a hole. The +conversion is done by pressing *!Ctrlh* with the crosshair over +the via. Conceptually it is still a via, but it has no copper annulus. +If you create such a hole in the middle of two polygons on different +layers, it will short the layers. Theoretically you could arrange for +such a hole not to be plated, but a metal screw inserted in the hole +would still risk shorting the layers. A good rule is to realize that +holes in the board really are vias between the layers and so place them +where they won't interfere with connectivity. You can convert a hole +back into a normal via with the same keystroke used to convery it in +the first place. + + +File: pcb.info, Node: Elements, Next: Pastebuffer, Prev: Vias, Up: Drawing and Removing + +Elements +-------- + + Some of the functions related to elements only work if both the +package layer and the pin layer are switched on. + + Now that you're familiar with many of the basic commands, it is time +to put the first element on the layout. First of all, you have to load +data into the paste buffer. There are four ways to do this: + 1) load the data from a library + 2) load the data from a file + 3) copy data from an already existing element + 4) convert objects in the buffer into an element + We don't have any elements on the screen yet nor anything in the +buffer, so we use number one. + + Select *lsi* from the menu in the library window press ** +twice at the appropriate text-line to get the MC68030 CPU. The data is +loaded and the mode is switched to *pastebuffer-mode*. Each notify +event now creates one of these beasts. Leave the mode by selecting a +different one or by *Escape* which resets all modes.. The +crosshair is located at the *mark* position as defined by the data +file. Rotating the buffer contents is done by selecting the *rotate* +entry of the *Buffer* menu or by pressing *ShiftF3*. The contents +of the buffer are valid until new data is loaded into it either by a +cut-to-buffer operation, copy-to-buffer operation or by loading a new +data file. There are 5 buffers available. Switching between them is +done by selecting a menu entry or by *Shift1..5*. Each of the two +board sides has its own buffers. + + The release includes all data files for the circuits that are used +by the demo layout. The elements in the LED example are not found in +the library, but you can lift them from the example itself if you want. +If you have problems with the color of the crosshair, change the +resource *crosshairColor* setting to a different one. + + Now load a second circuit, the MC68882 FPU for example. Create the +circuit as explained above. You now have two different unnamed +elements. Unnamed means that the layout-name of the element hasn't been +set yet. Selecting *description* from the *Display* menu displays the +description string of the two circuits which are CPU and FPU. The +values of the circuits are set to MC68030 and MC68882. Each of the +names of an element may be changed by *n* at the elements location +and editing the old name in the bottom input line. Naming pins and vias +is similar to elements. You can hide the element name so that it won't +appear on the board silkscreen by pressing *h* with the cursor +over the element. Doing so again un-hides the element name. + + Entering `:le' and selecting an element data file is the second way +to load circuits. + + The third way to create a new element is to copy an existing one. +Please refer to *Note Moving and Copying::. + + The fourth way to create a new element is to convert a buffer's +contents into an element. Here's how it's done: Select the Via-tool +from the *Tool pallette*. Set the grid spacing to something +appropriate for the element pin spacing. Now create a series of vias +where the pins go. Create them in pin number order. It is often handy +to place a reference point (*!Ctrlm*) in the center of the first +pin in order to measure the location of the other pins. Next make a +solder-side layer the active layer from the *active-layer* popup menu. +Now draw the outline of the element using lines and arcs. When you're +done, select everything that makes up the element with a box selection +(* drag, *). Now select "cut selection to buffer" +from the *Buffer* menu. Position the cursor over the center of pin 1 +and press the left button to load the data into the buffer. Finally +select "convert buffer to element" from the *Buffer* menu. You'll only +want to create elements this way if they aren't already in the library. +It's also probably a good idea to do this before starting any of the +other aspects of a layout, but it isn't necessary. + + To display the pinout of a circuit move to it and press *Shiftd* +or select *show pinout* from the *Objects* menu. A new window pops up +and displays the complete pinout of the element. This display can be +difficult to read if the component has been rotated 90 degrees :-( +therefore, the new window will show an un-rotated view so the pin names +are readable. *d* displays the name of one or all pins/pads +inside the drawing area, this is only for display on-screen, it has no +effect on any printing of the layout. + + You also may want to change a pin's or pad's current size by pressing +*s* to increase or *Shifts* to decrease it. While this is +possible, it is not recommended since care was probably taken to define +the element structure in the first place. You can also change the +thickness of the element's silkscreen outline with the same keys. You +can change whether a pin or SMD pad is rounded or square with the +*q*. SMD pads should usually have squared ends. Finally, you can +change whether the non-square pins are round or octagonal with the +*!Ctrlo*. + + SMD elements and silkscreen objects are drawn in the "invisible +object" color if they are located on the opposite side of the board. + + For information on element connections refer to *Note Connection +Lists::. + + +File: pcb.info, Node: Pastebuffer, Prev: Elements, Up: Drawing and Removing + +Pastebuffer +----------- + + The linestack and element-buffer of former releases have been +replaced by 5 multi-purpose buffers that are selected by +*Shift1..5*. The status line shows which buffer is the active one. +You may load data from a file or layout into them. Cut-and-paste works +too. If you followed the instructions earlier in this chapter you +should now have several objects on the screen. Move the crosshair to +one of them and press ** to toggle its selection flag. (If +you drag the mouse while the button is down, a box selection will be +attempted instead of toggling the selection.) The object is redrawn in +a different color. You also may want to try moving the pointer while +holding the third button down and release it on a different location. +This selects all objects inside the rectangle and unselects everything +else. If you want to add a box selection to an existing selection, +drag with *Mod1* instead. Dragging *Shift Mod1* +unselects objects in a box. Now change to *pastebuffer-mode* and +select some operations from the *Buffer* menu. Copying objects to the +buffer is available as *Mod1c* while cutting them uses +*Mod1x* as shortcut. Both clear the buffer before new data is +added. If you use the menu entries, you have to supply a crosshair +position by pressing a mouse button. The objects are attached to the +pastebuffer relative to that crosshair location. Element data or PCB +data may be merged into an existing layout by loading the datafiles +into the pastebuffer. Both operations are available from the *File* +menu or as user commands. + + +File: pcb.info, Node: Moving and Copying, Next: Loading and Saving, Prev: Drawing and Removing, Up: Getting Started + +Moving and Copying +================== + + All objects can be moved including element-names, by **, +draging the pointer while holding the button down and releasing it at +the new location of the object. If you use *Mod1* instead, +the object is copied. Copying does not work for element-names of +course. You can move all selected objects with *Shift *. +This uses the Pastebuffer, so it will remove whatever was previously in +the Pastebuffer. Please refer to *Note Pastebuffer::. If you want to +give a small nudge to an object, but you don't think that the mouse +will give you the fine level of control that you want, you can position +the cursor over the object, press *[*, move it with the arrow +keys, then press *]* when it's at the desired position. Remember +that all movements are forced onto grid coordinates, so you may want to +change the grid spacing first. + + +File: pcb.info, Node: Loading and Saving, Next: Printing, Prev: Moving and Copying, Up: Getting Started + +Loading and Saving +================== + + After your first experience with `Pcb' you will probably want to save +your work. `:s name' passes the data to an external program which is +responsible for saving it. For details see *saveCommand* in *Note +Resources::. Saving also is available from the *File* menu, either +with or without supplying a filename. `Pcb' reuses the last filename if +you do not pass a new one to the save routine. + + To load an existing layout either select *load layout data* from the +*File* menu or use `:l filename'. A file select box pops up if you +don't specify a filename. Merging existing layouts into the new one is +supported either by the *File* menu or by `:m filename'. + + `Pcb' saves a backup of the current layout depending on the resource +*backup*. The file is named `/tmp/PCB.%i.backup'. During critical +sections of the program or when data would be lost it is saved as +`/tmp/PCB.%i.save'. *%i* is replaced by the process ID. + + +File: pcb.info, Node: Printing, Next: Connection Lists, Prev: Loading and Saving, Up: Getting Started + +Printing +======== + + `Pcb' now has support for device drivers, `PostScript', +*encapsulated PostScript*, and *Gerber X* drivers are available so far. +The *Gerber X* driver generates a NC drill file for automated drilling. +I recommend the use of `GhostScript' if you don't have a `PostScript' +printer for handling the PostScript output. Printing always generates a +complete set of files for a specified driver. See the page about the +*Print()* action for addtional information about the filenames. The +control panel offers a number of options. Most of them are not avilable +for Gerber output because it wouldn't make sense, for example, to +scale the gerber output (you'd get an incorrectly made board!) The +options are: + +`device' + The top menu button selects from the available device drivers. + +`rotate' + Rotate layout 90 degrees counter-clockwise before printing + (default). + +`mirror' + Mirror layout before printing. Use this option depending on your + production line. + +`color' + Created colored output. All colors will be converted to black if + this option is inactive. + +`outline' + Add a board outline to the output file. The size is determined by + the maximum boardsize changeable from the *sizes* menu. The + outline appears on the top and bottom sides of the board, but not + on the internal layers. An outline can be useful for determining + where to shear the board from the panel, but be aware that it + creates a copper line. Thus it has the potential to cause short + circuits if you don't leave enough room from your wiring to the + board edge. Use a viewer to see what the output outline looks like + if you want to know what it looks like. + +`alignment' + Additional alignement targets are added to the output. The + distances between the board outline is set by the resource + *alignmentDistance*. Alignment targets should only be used if you + know for certain that YOU WILL BE USING THEM YOURSELF. It is + extremely unlikely that you will want to have alignment targets if + you send gerber files to a commercial pcb manufacture to be made. + +`scaling' + It's quite useful to enlarge your printout for checking the layout. + Use the scrollbar to adjust the scaling factor to your needs. + +`media' + Select the size of the output media from this menu. The user + defined size may be set by the resource *media* either from one of + the well known paper sizes or by a `X11' geometry specification. + This entry is only available if you use `X11R5' or later.

This is probably +best done in conjunction with a net-list file: see *Note Rats Nest::. +The following examples give more rudimentary ways to examine the +connections. + 1) create at least two elements and name them + 2) create some connections between their pins + 3) optionally add some vias and connections to them + + Now select *lookup connection* from the *Connections* menu, move the +cursor to a pin or via and press any mouse button. `Pcb' will look for +all other pins and/or vias connected to the one you have selected and +display the objects in a different color. Now try some of the reset +options available from the same menu. + + There also is a way to scan all connections of one element. Select +*a single element* from the menu and press any button at the element's +location. All connections of this element will be saved to the +specified file. Either the layout name of the element or its canonical +name is used to identify pins depending on the one which is displayed +on the screen (may be changed by *Display* menu). + + An automatic scan of all elements is initiated by choosing *all +elements*. It behaves in a similar fashion to scanning a single element +except the resource *resetAfterElement* is used to determine if +connections should be reset before a new element is scanned. Doing so +will produce very long lists because the power lines are rescanned for +every element. By default the resource is set to *false* for this +reason. + + To scan for unconnected pins select *unused pins* from the same menu. + + +File: pcb.info, Node: Selection, Next: Rats Nest, Prev: Connection Lists, Up: Getting Started + +Selection +========= + + Some commands mentioned earlier in this chapter also are able to +operate on all selected and visible objects. Now go back to the layout +and toggle the selection flag of a single one by **. Try +**, move the pointer while holding the button down and +release it on a different location. This selects all objects inside +the rectangle and unselects everything else. Dragging with +*Mod1* adds everything in the box to the existing selection. +Dragging *Shift * unselects objects in the box. + + The entries of the *Selection* menu are hopefully self-explanatory. +Many of the *Action Commands* can take various key words that make them +function on all or some of the selected items. + + +File: pcb.info, Node: Rats Nest, Next: Design Rule Checking, Prev: Selection, Up: Getting Started + +Rats Nest +========= + + If you have a netlist that corresponds to the layout you are working +on, you can use the rats-nest feature to add rat-lines to the layout. +First you will need to load a netlist file (see *:rn*, *Note User +Commands::). *w* adds rat-lines on the active layer using the +current line thickness shown in the status line (usually you'll want +them to be thin lines). Only those rat-lines that fill in missing +connectivity (since you have probably routed some connections already) +are added. If the layout is already completely wired, nothing will be +added, and you will get a message that the wiring is complete. + + Rat-lines are lines having the special property that they only +connect to pins and pads at their end points. Rat-lines are drawn on +the screen with a stippled pattern to make them easier to identify +since they have special behavior and cannot remain in a completed +layout. Rat-lines are added in the minimum length straight-line tree +pattern (always ending on pins or pads) that satisfies the missing +connectivity in the circuit. Used in connection with moves and rotates +of the elements, they are extremely useful for deciding where to place +elements on the board. The rat-lines will always automatically +rubberband to the elements whether or not the rubberband mode is on. +The only way for you to move them is by moving the parts they connect +to. This is because it is never desireable to have the rat-lines +disconnected from their element pins. Rat-lines will normally +criss-cross all over which gives rise to the name "rats nest" +describing a layout connected with them. If a SMD pad is unreachable +on the active layer, a warning will be issued about it and the rat-line +to that pad will not be generated. + + A common way to use rats nests is to place some elements on the +board, add the rat-lines, and then use a series of moves/rotates of the +elements until the rats nest appears to have minimum tangling. You may +want to iterate this step several times. Don't worry if the layout +looks messy - as long as you can get a sense for whether the +criss-crossing is better or worse as you move things, you're fine. +After moving some elements arround, you may want to optimize the rats +nest *o* so that the lines are drawn between the closest points +(this can change once you've moved components). Adding rat-lines only +to selected pads/pins (*Shiftw*) is often useful to layout a +circuit a little bit at a time. Sometimes you'll want to delete all +the rat-lines (*e*) or selected rat-lines (*Shifte*) in order +to reduce confusion. With a little practice you'll be able to achieve +a near optimal component placement with the use of a rats nest. + + Rat-lines are not only used for assisting your element placement, +they can also help you to route traces on the board. Use the *m* +to convert a rat-line under the cursor into a normal line on the active +layer. Inserting a point into a rat-line will also cause the two new +lines to be normal lines on the board. Another way that you can use +rat-lines is to use the *f* with the cursor over a pad or pin. +All of the pins and pads and rat-lines belonging to that net will be +highlighted. This is a helpful way to distinguish one net from the rest +of the rats nest. You can then route those tracks, turn off the +highlighting (*Shiftf*) and repeat the process. This will work even +if the layer that the rat-lines reside on is made invisible - so only +the pins and pads are highlighted. Be sure to erase the rat-lines +(*e* erases them all) once you've duplicated their connectivity by +adding your own lines. When in doubt, the *o* will delete only +those rat-lines that are no longer needed. + + If connections exist on the board that are not listed in the netlist +when *w* is pressed, warning messages are issued and the affected +pins and pads are drawn in a special *warnColor* until the next +*Notify()* event. If the entire layout agrees completely with the +netlist, a message informs you that the layout is complete and no +rat-lines will be added (since none are needed). If the layout is +complete, but still has rat-lines then you will be warned that +rat-lines remain. If you get no message at all it's probably because +some elements listed in the net list can't be found and where reported +in an earlier message. There shouldn't be any rat-lines left in a +completed layout, only normal lines. + + The *Shiftw* is used to add rat-lines to only those missing +connections among the selected pins and pads. This can be used to add +rat-lines in an incremental manner, or to force a rat-line to route +between two points that are not the closest points within the net. +Often it is best to add the rats nest in an incremental fashion, laying +out a sub-section of the board before going further. This is easy to +accomplish since new rat-lines are never added where routed +connectivity already makes the necessary connections. + + +File: pcb.info, Node: Design Rule Checking, Prev: Rats Nest, Up: Getting Started + +Design Rule Checking +==================== + + After you've finished laying out a board, you may want to check to +be certain that none of your interconnections are too closely spaced or +too tenuously touching to be reliably fabricated. The design rule +checking (DRC) function does this for you. Use the command ":DRC()" +(without the quotes of course) to invoke the checker. If there are no +problem areas, you'll get a message to that effect. If any problem is +encountered, you will get a message about it and the affected traces +will be highlighted. One part of the tracks of concern will be +selected, while the other parts of concern will have the +"FindConnection" highlighting. The screen will automatically be +centered in the middle of the object having the "FindConnection" +(Green) highlighting. The middle of the object is also the coordinates +reported to be "near" the problem. The actual trouble region will be +somewhere on the boundary of this object. If the two parts are from +different nets then there is some place where they approach each other +closer than the minimum rule. If the parts are from the same net, then +there is place where they are only barely connected. Find that place +and connect them better. + + After a DRC error is found and corrected you must run the DRC again +because the search for errors is halted as soon as the first problem is +found. Unless you've been extremely careless there should be no more +than a few design rule errors in your layout. The DRC checker does not +check for minimum spacing rules to copper text, so always be very +careful when adding copper text to a layout. The rules for the DRC are +specified in the application resource file. The minimum spacing value +(in mils) is given by the *Settings.Bloat* value. The default is 7 +mils. The minimum touching overlap (in mils) is given by the +*Settings.Shrink* value. This value defaults to 5 mils. Check with your +fabrication process people to determine the values that are right for +you. + + If you want to turn off the highlighting produced by the DRC, +perform an undo (assuming no other changes have been made). To restore +the highlighting, use redo. The redo will restore the highlighting +quickly without re-running the DRC checker. + + +File: pcb.info, Node: User Commands, Next: Command-Line Options, Prev: Getting Started, Up: Top + +User Commands +************* + + The entering of user-commands is initiated by the action routine +*Command()* (the `(":")' character) and finished by either *Return* +or *Escape* to confirm or to abort.

If no filename is given a file select + box will pop up. The file is read via the command defined by the + *RatCommand* resource. The command must send its output to + *stdout*. The netlist received by pcb must have this simple text + form: + + netname NAME-PINNUM NAME2-PINNUM2 NAME3-PINNUM3 ... [\] + + where "netname" is the name of the net (currently its value is + ignored but it must be present nonetheless), NAME is the + layout-name given to an element, and PINNUM is the (usually + numeric) pin number of the element that is part of the net (see + *Note Element Objects:: for details on pin numbering). Spaces or + tabs separate the fields. If the line ends with a "\" the net + continues on the next line and the "\" is treated exactly as if it + were a space. If the NAME ends with a lower-case letter, all + lower-case letters are stripped from end of the NAME to determine + the matching name-on-board name. For example: + + Data U1-3 U2abc-4 FLOP1a-7 Uabc3-A9 + + would specifiy that pin 3 of U1 be connected to pin 4 of U2, to + pin 7 of FLOP1 and to pin A9 of Uabc3. Note that if pin numbers + contain alphabetic characters, they must match the case contained + in the "number" string defining the pin number on the + cooresponding element. It is up to you to name the elements so + that their layout-names agrees with the netlist.

This file normally resides in the +`X11/lib/app-defaults' directory and is called `Pcb'. The bindings to +which the manual refers to are the ones as defined by the shipped +resource file. Besides binding an action to an X11 event, you can also +execute any action command using a ":" command (see *Note User +Commands::). + + Take special care about translations related to the functions keys +and the pointer buttons because most of the window managers use them +too. Change the file according to your hardware/software environment. +You may have to replace all occurances of *baseTranslations* to +*translations* if you use a `X11R4' server. + + Passing *Object* as an argument to an action routine causes the +object at the cursor location to be changed, removed or whatever. If +more than one object is located at the crosshair position the smallest +type is used. If there are two of the same type the newer one is taken. +*SelectedObjects* will handle all selected and visible objects. + +`AddRats(AllRats|SelectedRats)' + Adds rat-lines to the layout using the loaded netlist file (see + the *:rn*, *Note User Commands::.). Rat lines are added on the + active layer using the current line thickness shown in the status + line. Only missing connectivity is added by the AddRats command + so if, for example, the layout is complete nothing will be added. + Rat lines are drawn on the screen with a stippled pattern to make + them easier to identify since they cannot appear in a completed + layout. The rat-lines are added in the minimum length + straight-line tree pattern (always ending on pins or pads) that + satisfies the missing connectivity in the circuit. If a SMD pad + is unreachable on the active layer, a warning will be issued about + it and the rat-line to that pad will not be generated. If + connections exist on the board which are not listed in the netlist + while AllRats are being added, warning messages will be issued and + the affected pins and pads will be drawn in a special *warnColor* + until the next *Notify()* event. If the entire layout agrees + completely with the net-list a message informs you that the layout + is complete and no rat-lines are added (since none are needed). + If *SelectedRats* is passed as the argument, only those missing + connections that might connect among the selected pins and pads + are drawn.

Before the + first action in a group, Atomic(Save) should be issued. After + each action that might be undoable, Atomic(Restore) should be + issued. Atomic(Block) concludes and save the undo grouping if + there was anything in the group to undo. Atomic(Close) concludes + and save the undo grouping even if nothing was actually done. + Thus it might produce an "empty" undo.

Default: + !Mod1s: Change2ndSize(Object, +5) + !Mod1 Shifts: Change2ndSize(Object, -5) + +`ChangeHole(Object|SelectedVias)' + This action routine converts a via to and from a hole. A hole is + a via that has no copper annulus. The drill size for the via + determines the hole diameter. + !Ctrlh: ChangeHole(Object) + +`ChangeName(Object)' +`ChangeName(Layer|Layout)' + Changes the name of the visible object at the cursor location. A + text object doesn't have a name therefore the text string itself + is changed. The element name currently used for display is always + the one changed with this command.

Range + checking is done to insure that none of the maximum/minimums of + any size are violated. If *Object* is passed then a single object + at the cursor location is changed. If any of the *Selected* + arguments are passed then all selected and visible objects of that + type are changed. If the type being modified is an element, then + the thickness of the silkscreen lines defining the element is + changed. Default: + Nones: ChangeSize(Object, +5) + !Shifts: ChangeSize(Object, -5) + +`ChangeSquare(Object|SelectedElements|SelectedPins)' + Toggles the setting of the square flag. The flag is used to + identify a certain pin, normally the first one, of circuits. It is + also used to make SMD pads have square ends. + Noneq: ChangeSquare(Object) + +`Command()' + Calling *Command()* pops up an input line at the bottom of the + window which allows you to enter commands. Including all action + commands! The dialog ends when *NoneReturn* to confirm or + *NoneEscape* to abort is entered. Default: + colon: Command() + +`Connection(Find)' +`Connection(ResetFoundLinesAndRectangles|ResetPinsViasAndPads|Reset)' + The *Connection()* action is used to mark all connections from one + pin, line or via to others. The *ResetFoundLinesAndRectangles, + ResetFoundPinsAndVias* and *Reset* arguments may be used to reset + all marked lines and rectangles, vias and pins or all of them. The + search starts with the pin or via at the cursor position. All + found objects are drawn with the color defined by the resource + *connectedColor*. See also, + *Display(Description|NameOnPCB|Value)*. Default: + !Shiftc: Connection(Reset) + Nonef: Connection(Find) + !Shiftf: Connection(Reset) + +`DeleteRats(AllRats|SelectedRats)' + This routine deletes either all rat-lines in the layout, or only + the selected and visible ones. Non-rat-lines and other layout + objects are unaffected. Default: + Nonee: DeleteRats(AllRats) + !Shifte: DeleteRats(SelectedRats) + +`Display(Description|NameOnPCB|Value)' +`Display(Toggle45Degree|CycleClip)' +`Display(Grid|ToggleGrid)' +`Display(ToggleRubberBandMode)' +`Display(Center|ClearAndRedraw|Redraw)' +`Display(Pinout|PinOrPadName)' + This action routines handles some output related settings. It is + used to center the display around the cursor location and to + redraw the output area optionally after clearing the window. + Centering is done with respect to the *grid* setting. Displaying + the grid itself may be switched on and off by *Grid* but only if + the distance between two pixels exceeds 1_DISTANCE pixels. `Pcb' + is able to handle several labels of an element. One of them is a + description of the functionality (eg resistor), the second should + be a unique identifier (R1) whereas the last one is a value (100k). + The *Display()* action selects which of the names is displayed. + It also controls which name will be affected by the *ChangeName* + command. If *ToggleGrid* is passed, `Pcb' changes between relative + ('rel' in the statusline) and absolute grid (an 'abs' in the + statusline). Relative grid means the pointer position when the + command is issued is used as the grid origin; while (0,0) is used + in the absolute grid case. Passing *Pinout* displays the pinout + of the element at the current cursor location whereas + *PinOrPadName* toggles displaying of the pins or pads name under + the cursor. If none of them matches but the cursor is inside of an + element, the flags is toggled for all of its pins and pads.

Must be + repeated until no errors are found. + +`EditLayerGroups()' + Pops up a dialog box to edit the layergroup setting. The function + is also available from the *Objects* menu. There are no defaults. + +`Load(ElementToBuffer|Layout|LayoutToBuffer|Nelist)' + This routine pops up a fileselect box to load layout, element data, + or netlist. The passed filename for layout data is saved and may + be reused. *ElementToBuffer* and *LayoutToBuffer* load the data + into the current buffer. There are no defaults. + +`MarkCrosshair()' + This routine marks the current cursor location with an X, and then + the cursor display shows both absolute position and position + relative to the mark. If a mark is already present, this routine + removes it and stops displaying relative cursor coordinates. + Defaults: + !Ctrlm: MarkCrosshair() + +`Mode(Copy|InsertPoint|Line|Move|None|PasteBuffer|Polygon|Thermal)' +`Mode(Remove|Rectangle|RubberbandMove|Text|Via)' +`Mode(Cycle)' +`Mode(Notify)' +`Mode(Save|Restore)' + Switches to a new mode of operation. The active mode is displayed + by a thick line around the matching mode selector button. Most of + the functionality of `Pcb' is implemented by selecting a mode and + calling *Mode(Notify)*. The arguments *Line*, *Polygon*, + *Rectangle*, *Text* and *Via* are used to create the appropriate + object whenever *Mode(Notify)* is called. Some of them, such as + *Polygon*, need more than one call for one object to be created. + *InsertPoint* adds points to existing polygons or lines. *Save* + and *Restore* are used to temporarily save the mode, switch to + another one, call *Mode(Notify)* and restore the saved one. Have a + look at the application resource file for examples. *Copy* and + *Move* modes are used to change an object's location and, + optionally, to create a new one. The first call of *Mode(Notify)* + attaches the object at the pointer location to the crosshair + whereas the second one drops it to the layout. The *rubberband* + version of move performs the move while overriding the current + rubberband mode. Passing *PasteBuffer* attaches the contents of + the currently selected buffer to the crosshair. Each call to + *Mode(Notify)* pastes this contents to the layout. *Mode(Cycle)* + cycles through the modes available in the mode-button pallete. + *Mode(None)* switches all modes off.

The `X' server's pointer follows because + the necessary events are generated by `Pcb'. All movements are + performed with respect to the currently set grid value. Default: + NoneUp: MovePointer(0, -1) + !ShiftUp: MovePointer(0, -10) + NoneDown: MovePointer(0, 1) + !ShiftDown: MovePointer(0, 10) + NoneRight: MovePointer(1, 0) + !ShiftRight: MovePointer(10, 0) + NoneLeft: MovePointer(-1, 0) + !ShiftLeft: MovePointer(-10, 0) + +`MoveToCurrentLayer(Object|SelectedObjects)' + The function moves a single object at the crosshair location or + all selected objects to the current layer. Elements are not + moveable by this function. They have to be deleted and replaced + on the other side. If a line segment is moved and the movement + would result in a loss of connectivity to another segment then + via(s) are automatically added to maintain the connectivity. + Nonem: MoveToCurrentLayer(Object) + !Shiftm: MoveToCurrentLayer(SelectedObjects) + +`New()' + Clear the current layout and starts a new one after entering its + name. Refer to the resource *backup* for more information. No + defaults. + +`PasteBuffer(AddSelected|Clear|1..5)' +`PasteBuffer(Rotate, 1..3)' +`PasteBuffer(Convert)' + This action routine controls and selects the pastebuffer as well + as all cut-and-paste operations. Passing a buffer number selects + one in of the range 1..5. The statusline is updated with the new + number. *Rotate* performs a number of 90 degree counter clockwise + rotations of the buffer contents. *AddSelected* as first argument + copies all selected and visible objects into the buffer. Passing + *Clear* removes all objects from the currently selected buffer. + *Convert* causes the contents of the buffer (lines, arc, vias) to + be converted into an element definition. Refer to *Note + Pastebuffer:: for examples. Default: + !Ctrlx: PasteBuffer(Clear) PasteBuffer(AddSelected) + Mode(PasteBuffer) + !Shift Ctrlx: PasteBuffer(Clear) PasteBuffer(AddSelected) + RemoveSelected() Mode(PasteBuffer) + !Mod1c: PasteBuffer(Clear) PasteBuffer(AddSelected) + !Mod1x: PasteBuffer(Clear) PasteBuffer(AddSelected) + RemoveSelected() + !Shift1: PasteBuffer(1) + !Shift2: PasteBuffer(2) + !Shift3: PasteBuffer(3) + !Shift4: PasteBuffer(4) + !Shift5: PasteBuffer(5) + NoneF3: Mode(PasteBuffer) + +`Polygon((Close|PreviousPoint)' + Polygons need a special action routine to make life easier. Calling + *Polygon(PreviousPoint)* resets the newly entered corner to the + previous one. The Undo action will call Polygon(PreviousPoint) + when appropriate to do so. *Close* creates the final segment of + the polygon. This may fail if clipping to 45 degree lines is + switched on, in which case a warning is issued. Default: + Nonep: Polygon(Close) + !Shiftp: Polygon(Close) + +`Print()' + Pops up a print control box that lets you select the output + device, scaling and many more options. Each run creates all files + that are supported by the selected device. These are mask files as + well as drilling files, silk screens and so on. The table shows + the filenames for all possible files: + POSIX (extention) 8.3 filename + --------------------------------------------- + *_componentmask.* cmsk.* + *_componentsilk.* cslk.* + *_soldermask.* smsk.* + *_soldersilk.* sslk.* + *_drill.* dril.* + *_groundplane.* gpl.* + *_group[1..8].* [..8].* + The output may be sent to a postprocessor by starting the filename + with the *pipe* `("|")' character. Any `"%f"' in a command is + replaced with the current filename. The function is available from + the *file* menu. There are no defaults. + +`Quit()' + Quits the application after confirming the operation. Default: + WM_PROTOCOLS: Quit() + +`Redo()' + This routine allows you to recover from the last undo command. + You might want to do this if you thought that undo was going to + revert something other than what it actually did (in case you are + confused about which operations are un-doable), or if you have + been backing up through a long undo list and over-shoot your + stopping point. Any change that is made since the undo in + question will trim the redo list. For example if you add ten + lines, then undo three of them you could use redo to put them + back, but if you move a line on the board before performing the + redo, you will lose the ability to "redo" the three "undone" lines. + Default: + !Shiftr: Redo() + +`RemoveSelected()' + This routine removes all visible and selected objects. There are + no defaults. + +`Report(Object|DrillReport)' + This routine pops up a dialog box describing the various + characteristics of an object (or piece of an object such as a pad + or pin) in the layout at the cursor position, or a report about + all of the drill holes in the layout. There are no defaults. + +`RouteStyle(1|2|3|4)' + This routine copies the sizes corresponding to the numbered route + style into the active line thicknes, via diameter, and via drill + size. Defaults: + !Ctrl1: RouteStyle(1) + ... + !Ctrl4: RouteStyle(4) + +`Save(Layout|LayoutAs)' +`Save(AllConnections|AllUnusedPins|ElementConnections)' + Passing *Layout* saves the layout using the file from which it was + loaded or, if it is a new layout, calls *Save(LayoutAs)* which + queries the user for a filename. The values: *AllConnections*, + *AllUnusedPins* and *ElementConnections* start a connection scan + and save all connections, all unused pins or the connections of a + single element to a file. There are no defaults. + +`Select(All|Block|Connection|ToggleObject)' +`Select(ElementByName|ObjectByName|PadByName|PinByName)' +`Select(TextByName|ViaByName)' + Toggles either the selection flag of the object at the crosshair + position (*ToggleObject*) or selects all visible objects, all + inside a rectangle or all objects which have been found during the + last connection scan. The *ByName* functions use a regular + expression search, always case insensitive, to select the objects. + Default: + None: Select(ToggleObject) + None,None: See resource file - this is complex + +`SetValue(Grid|LineSize|TextScale|ViaDrillingHole|ViaSize|Zoom, value)' + Some internal values may be changed online by this function. The + first parameter specifies which data has to be changed. The other + one determines if the resource is set to the passed value, if + *value* is specified without sign, or increments/decrements if it + is specified with a plus or minus sign. The function doesn't + change any existing object only the initial values of new objects. + Use the *ChangeSize()* and *ChangeDrillSize()* to change existing + objects. Default: + Noneg: SetValue(Grid, +5) + !Shiftg: SetValue(Grid, -5) + Nonel: SetValue(LineSize, +5) + !Shiftl: SetValue(LineSize, -5) + Nonet: SetValue(TextScale, +10) + !Shiftt: SetValue(TextScale, -10) + Nonev: SetValue(ViaSize, +5) + !Shiftv: SetValue(ViaSize, -5) + !Mod1v: SetValue(ViaDrillingHole, +5) + !Mod1 Shiftv: SetValue(ViaDrillingHole, -5) + Nonez: SetValue(Zoom, -1) + !Shiftz: SetValue(Zoom, +1) + +`SwapSides()' + This routine changes the board side you are viewing. Default: + NoneTab: SwapSides() + +`SwitchDrawingLayer(value)' + Makes layer numer 1..8 the current one. Default: + None1: SwitchDrawingLayer(1) + ... + None8: SwitchDrawingLayer(8) + +`ToggleHideName(Object|SelectedElements)' + Toggles whether the element's name is displayed or hidden. If it + is hidden you won't see it on the screen and it will not appear on + the silk layer when you print the layout. + Noneh: ToggleHideName(Object) + !Shifth: ToggleHideName(SelectedElements) + +`Undo()' +`Undo(ClearList)' + The unlimited undo feature of `Pcb' allows you to recover from + most operations that materially affect you work. Calling *Undo()* + without any parameter recovers from the last (non-undo) operation. + *ClearList* is used to release the allocated memory. *ClearList* + is called whenever a new layout is started or loaded. See also + *Redo*. Default: + Noneu: Undo() + !Shift Ctrlu: Undo(ClearList) + +`Unselect(All|Block|Connection)' + Unselects all visible objects, all inside a rectangle or all + objects which have been found during the last connection scan. + Default: + !Shift : Mode(Save) Mode(None) Unselect(Block) + !Shift : Unselect(Block) Mode(Restore) + + +File: pcb.info, Node: Translations, Prev: Actions, Up: X11 Interface + +Default Translations +==================== + + This section covers some default translations of key and button +events as defined in the shipped default application resource file. +Most of them have already been listed in *Note Actions::. `Pcb' makes +use of a nice `X11' feature; calling several action routines for one +event. + +`NoneBackSpace:' + +`NoneDelete:' +`!ShiftBackSpace:' +`!Shift Ctrl:' + The object at the cursor location is removed by + *NoneBackSpace* or *Shift Ctrl* whereas + *ShiftBackSpace* also removes all other objects that are + fully-connected to the one at the cursor location. + +`!Mod1 CtrlLeft:' +`!Mod1 CtrlRight:' +`!Mod1 CtrlUp:' +`!Mod1 CtrlDown:' + Scroll one page in one of the four directions. + +`NoneLeft:, !ShiftLeft:' +`NoneRight:, !ShiftRight:' +`NoneUp:, !ShiftUp:' +`NoneDown:, !ShiftDown:' + Move crosshair either one or ten points in grid. + +`NoneReturn:' + Finished user input, selects the 'default' button of dialogs. + +`NoneEscape:' + *Mode(Reset)*, aborts user input, selects the 'abort' button of + dialogs or resets all modes. + +`None, Btn2, None:' +`!Mod1, Btn2, !Mod1:' + The first sequence moves the object or element name at the cursor + location.

They therefore share a common definition in +the macro file but are defined with two different value labels. + + The macro file entry: + define(`Description_43256_dil', `SRAM 32Kx8') + define(`Param1_43256_dil', 28) + define(`Param2_43256_dil', 600) + define(`PinList_43256_dil', ``pin1', `pin2', ...') + + And the list file: + 43256_dil:N:43256:62256 + + The macro must define a description, the pin list and up to two +additional parameters that are passed to the package definitions. The +first one is the number of pins whereas the second one defines for +example the width of a package. + + It is very important to select a unique identifier for each macro. In +the example this would be *43256_dil* which is also the templates name. +It is required by some low-level macros that *Description_, Param1_, +Param2_* and *PinList_* are prepended. + + The list file uses a syntax: + template:package:value[:more values] + + This means that the shown example will create two element entries +with the sam package and pinout but with different names. + + A number of packages are defined in `common.m4'. Included are: + + DIL packages with suffix D, DW, J, JD, JG, N, NT, P + PLCC + TO3 + generic connectors + DIN 41.612 connectors + zick-zack (SD suffix) + 15 pin multiwatt + + If you are going to start your own library please take care about +`m4' functions. Be aware of quoting and so on and, most important check +your additional entry by calling the macro: + + CreateObject(`template', `value', `package suffix') + + If quoting is incorrect an endless loop may occur (broken by a +out-of-memory message). + + The scripts in the `lib' directory handle the creation of libraries +as well as of their contents files. Querying is also supported. + + I know quite well that this description of the library +implementation is not what some out there expect. But in my opinion +it's much more useful to look at the comments and follow the macros +step by step. + + +File: pcb.info, Node: Installation, Prev: File Formats, Up: Top + +Installation and Troubleshooting +******************************** + + Compiling and installing the package should be straightforward. If +any problems occur, please contact the author +(Thomas.Nau@rz.uni-ulm.de) to find a solution and include it into the +next release. + +* Menu: + +* compiling:: Compiling and installing. +* problems:: Troubleshooting. + + +File: pcb.info, Node: compiling, Next: problems, Up: Installation + +Compiling and Installing +======================== + + This section covers the steps which are necessary to compile the +package. + +* Menu: + +* config.h:: Editing `config.h' options. +* manuals:: Creating the man page, info file and this manual. +* make:: Creating the `Makefile', compiling and installing. + + +File: pcb.info, Node: config.h, Next: manuals, Up: compiling + +Editing config.h +---------------- + + Most `X11' related options are automatically covered by `imake' +which is called from `xmkmf'. The ones special to `Pcb' have to be +edited in `config.h'. In order of appearance: + +`INFOLIBDIR' + must be set to the directory where your GNU info files are located. + +`/usr/X11R6/lib/X11/pcb' + is the path of a directory where the font files will be installed. + +`DEFAULTFONT' + the name of the default font file. + +`DEFAULTLIBRARY' + the name of the default library. + +`gm4' + the name of GNUs m4 version. + +`Mod1' + If your window manager has already bound *Mod1* together with some + function keys you may want to change this setting. This is true + for HP-VUE. + +`EXTRA_INCLUDES' + Some systems do not have the Athena Widget include files in their + normal place as configured by `X11's config files. Define this as + follows: + EXTRA_INCLUDES = -I/usr/openwin/share/include + This is probably true for Suns which use `OpenWindows'. + +`PATCHES' + This symbol is passed to the compiler. Use it to define additional + compiler flags. Add the *-DNEED_STRDUP* flag, if your system does + not have a strdup() library function. + +`HAS_REGEX' + Set to *-DHAS_REGEX* if your system supports regular expressions. + This enables the actions *Select(*ByName)*. + +`EXITCALL' + The symbol *EXITCALL* should be defined according to the *call on + exit* functions supported by your system. There are three choices: + EXITCALL = -DHAS_ATEXIT if atexit() is supported (SYSV) + EXITCALL = -DHAS_ON_EXIT if on_exit() and no atexit() is supported + EXITCALL = if none of them is supported + Please check your manpages for details. + +`SYS_LIBRARIES' + This symbol is used to pass additional libraries to the linker. + The only additional libraries which are used are the math and lex + library. + + If you have to make system dependent changes please include them +into a *#ifdef Architecture* ... *#endif* construct and mail a copy to +the author (Thomas.Nau@rz.uni-ulm.de). + + Now run `xmkmf -a' which creates the `Makefiles' and runs `make +depend'. This should finish without any problems except some systems +which complain about missing include files. Don't worry about any such +warnings at this time, the package should compile without any problems. + + +File: pcb.info, Node: manuals, Next: make, Prev: config.h, Up: compiling + +Manuals +------- + + After `xmkmf -a' has created the new `Makefile' you are able to +create the manpages, the application resource, the info file, the `TeX' +output and a reference card by executing + (cd doc; make) + (cd src; make Pcb.ad) + You'll need `TeX', `texindex' and, if you want `PostScript', `dvips' +to build the manuals. Preformatted documentation for the default +configuration may be found in the `./doc.ps' directory. A simple +*make* builds everything.

It should build +everything without any errors. If it doesn't refer to *Note problems::. + + You have to be root to install the package or at least a user with +the appropriate priveleges in some `X11' directories. Set the umask to +*022* or else some files will not be found because the directory isn't +world readable. + + If you do not have the appropriate permissions you should run +`./pcbtest.sh' in the `src' directory to run `Pcb' from the +installation directory. + + `make install' and `make install.man' install the program, the +fonts, the application default resource file, all element and package +data as well as the manpage into the `X11' directories. `make +install.info' does the same for the `GNU' info file. + + +File: pcb.info, Node: problems, Prev: compiling, Up: Installation + +Troubleshooting +=============== + + There are some known problems. Most of them are related to missing +parts of a standard `X11' distribution. Some others are caused by third +party applications such as `X' servers. To make this list more complete +please mail your problems and, if available, solutions to the author. +The mail address may be found at the beginning of this chapter. In any +case, read *Note X11::. + + By the way, you `MUST HAVE AN ANSI COMPILER' to make `Pcb' work. + + If the shell script `create_sed_script.sh' fails with an error of +`awk' check your system for `nawk' or get the `GNU gawk'. See the +script for details. + + Another source of problems are older versions of `flex' and `bison'. +`Pcb' definitely works with `flex-2.4.7' and `bison-1.22' or later. The +problems will result in a *syntax error* while parsing files. You will +have to add *-lfl* to the SYS_LIBRARIES identifier in `Imakefile'. See +also, *Note FreeBSD::. + + The following list gives you just an idea because I'm not able to +test all `Pcb' releases on all platforms. + +* Menu: + +* HP:: Hewlett-Packard series 700 and 800 running HP-UX 10.* +* Sun:: Sun, Solaris 2.5 +* SGI:: SGI, IRIX 5.3 and 6.* +* DEC Alpha:: DEC Alpha, DEC UNIX 3.2c and 4.0 +* SCO:: SCO Unix ODT 3.0, PC hardware +* Linux:: Linux 0.99pl14 and later +* FreeBSD:: FreeBSD, NetBSD ... +* X11:: Refers to `X11R4', `X11R5', and `OpenWindows' +* TeX and Manuals:: Problems creating the `pcb.dvi' + + +File: pcb.info, Node: HP, Next: Sun, Up: problems + +HP Series 700 and 800 +--------------------- + + You have to install several `X11' tools (`imake') and include files +or, better, install a complete `X11R5' release. Hewlett-Packard doesn't +support the Athena Widgets. So the header files and libraries are +missing from the application media, but they are available as a patch. +They also do not ship the `ANSI' compiler with the normal operating +system release so you have to buy one or use `GCC'. Some of the tools +are available as patches. + + In addition, `Pcb' has been successfully tested on these platforms +with `HPUX 9.*, 10.*' running self-compiled `X11R5'. + + +File: pcb.info, Node: Sun, Next: SGI, Prev: HP, Up: problems + +Sun SPARC architecture +---------------------- + + There are no known problems with Sun machines if they use `X11R5' +instead of `OpenWindows'. `Pcb' compiled successfully with all kinds of +SPARCstations `Solaris-2.[345]'. + + For problems with `OpenWindows' refer to *Note X11::. + + If `xmkmf' is missing, try + /usr/openwin/bin/imake -DUseInstalled -I/usr/openwin/lib/config + make Makefile + make includes + make depend + instead.
