simulation models. Not just for debugging, but also great for learning and
teaching SimPy!
* A new document, describing API and tools for gaining insight into and
debugging SimPy models.
* Two tutorials showing the use of SimPy's advanced object oriented API.
was last updated.
Besides the upstream changes listed below, also add DESTDIR support
(which is enabled by better upstream support for it).
4. Version 7.5 Release Notes:
---------------------------------
Version 7.5 is the development branch. Version 7.5.0 is the same as
7.4.2, which is essentially the same as 7.3.123, plus some
documentation updates. Intended development is as follows:
1) Use a finely spaced grid for the database, but keep the concept
of "lambda" for layout. Keep backwards compatibility, and resolve
issues with layout that does not work well on the lambda grid.
Item #1 implemented in 7.5.1 by allowing a DRC "scalefactor" line,
which declares that all DRC rules are in units of (lambda /
scalefactor). Rules "in use" are scaled to lambda and rounded to
the nearest integer. The original value is retained, however, so
that any call to "scalegrid" will recompute the DRC distances based
on the current internal grid. Thus, we can define DRC rules in
fractional lambda and therefore match vendor DRC rule distances
while still maintaining magic's concept of "lambda". This means
that users working entirely within magic have scalable CMOS rules,
but if a "vendor cell" (3rd party GDS or CIF) is loaded, the DRC
rules will be correct with respect to it.
2) Create tile-based DRC functions that work like cifoutput: perform
tile operations, for which the resulting plane, instead of being
output as a file like CIF or GDS, simply becomes an error result
plane. This will become an extra built-in plane. Try to keep the
plane numbers down by removing the built-in routing planes when they
are not used.
Basically, this means that the top of the DRC section defines a set
of "templayer" blocks just like "cifinput" and "cifoutput" (but at the
same scaling as the layout (thus the main reason for item #1 above)),
where the templayer types can be used in the DRC section.
3) Add "cifoutput" operators as needed to form a complete DRC. Add DRC
rule types as needed to form a complete DRC (for example, it needs a
"copy" function that declares that the templayer itself represents the
error condition).
4. Version 7.4 Release Notes:
---------------------------------
Version 7.4 is the new stable distribution version of magic.
Apart from changes to the release notes, it is identical to
the last revision (123) of development version 7.3. Revisions
of 7.4 will be made as necessary to fix bugs in the code. All
new additions and major changes will be done to the new
development distribution, version 7.5. Therefore there will
not be a "What's new in 7.4" section, as there is not supposed
to be anything new in version 7.4.
5. Version 7.3 Release Notes:
---------------------------------
Magic release 7.3 incorporates a stacked contact model which is,
for the most part, backwardly compatible with Magic releases
7.2 and earlier. Information about this developmental release
can be found at:
http://opencircuitdesign.com/magic/magic7_3.html
What's new in 7.3:
------------------
Provided by Tim Edwards (MultiGiG, Inc.):
1) Stacked contact model allowing arbitrary stacking of
contact types.
2) A separate "undo/redo" method for network selection, to
remove the memory overhead associated with selecting and
unselecting large networks. Also removes some time overhead
as well, especially when unselecting networks.
3) Much improved "plot pnm" function.
4) Improved transistor and resistor extraction.
5) LEF format reader; improved LEF/DEF input/output handling
6) New style and colormap file formats
7) Vendor GDS read/write capability
8) "wire segment" drawing function
9) Handling of path records in CIF and GDS input
10) Handling of cell scaling in GDS input
11) Pi-network device extraction for resistors
12) Option to write contacts as cell arrays in GDS output
13) New "widespacing" and "maxwidth" DRC algorithms.
14) "polygon" command
15) New cifoutput operator "bloat-all"
16) Backing-store for 24-bit and OpenGL graphics
17) New "pick" tool for interactive selection move and copy
18) New interactive "wire" tool
19) Crosshair
20) New cifoutput operator "slots"
21) New fcntl-based file locking mechanism
22) "angstroms" units supported in cifinput/cifoutput
23) Non-Manhattan device extraction support
24) New "feedback" mechanism
25) Proper support for > 32 planes (up to 64)
26) Fixed array interaction CIF/GDS generation
27) Added executable "magicdnull" for streamlined batch-mode use
28) New method for crash backups, including restore with "magic -r"
29) A number of other technology file additions and enhancements
6. Version 7.2 Release Notes:
---------------------------------
Magic release 7.2 incorporates the capability to run magic from the Tcl
interpreter with graphics handled by Tk. Instructions for compiling
and installing this version are in README.Tcl. Information about
this release can be found at:
http://opencircuitdesign.com/magic/magic7_2.html
What's new in 7.2:
------------------
Provided by Tim Edwards (MultiGiG, Inc., and JHU Applied Physics Lab):
1) Tcl interpreter extension option
2) Cygwin compile option
3) Memory resources cleaned up
4) GUI interface to Tcl version of Magic
5) Readline update to version 4.3
6) OpenGL fixes and refinements
7) Nonmanhattan geometry fixes and extensions
8) Threaded graphics in non-Tcl environments
9) Inductance extraction
10) CIF and GDS input/output support for deep submicron technologies
11) Different internal and lambda grids, including automatic or
induced ("scalegrid" command) grid subdivision and expansion.
"snap" and "grid" functions and extensions aid layout when
lambda and internal units differ.
12) Removed commands "list", "listall", "parent", and "child",
replacing them with the more general-purpose "cellname"
and "instance" commands.
13) Added command "tech", and re-loadable technologies.
14) Revamped the "dstyle" files and updated the dstyle version
15) Added "element" types for layout annotation.
16) Extended extract section of techfile to include "device"
keyword and devices "mosfet", "bjt", "capacitor", and "resistor".
New model resistor and mosfet use width/length instead of area/
perimeter.
17) Added 3D rendering window invoked by command "specialopen wind3d",
for the Tcl version compiled with OpenGL graphics.
18) Added "height" keyword to tech file for height/thickness values
19) Added "windowname" command for managing multiple wrapper windows
under Tcl.
20) Added extraction extension for annular (ring) MOSFETs.
21) Added "widespacing" DRC rule.
22) Added GNU autoconf compile
23) New command "property" for setting key:value pair properties
in cell definitions that can be interpreted by other routines
(such as LEF/DEF).
24) General-purpose subcircuit method using the "port" command to
declare a cell to be a subcircuit and to mark the position and
orientation of connections into the subcell. This replaces a
method previously built into version 7.2 using a "subcircuit"
layer; that method is now considered obsolete.
25) LEF and DEF format readers, LEF format writer.
26) Improved techfile format with asterisk-notation and DRC
"surround", "overhang", and "rect_only" statements.
----------------
Release 20

command has been reinstated (it was previously disabled) and error messages now display
the corresponding line numberin the input deck.
* New Features: .measure command for transient, ac and dc analyses (still not complete, e.g.
DERIV is missing).
* Devices: Updated BISM4 model to revision 4.6.5. Added PWL (PieceWise Linear) functionality

- Fixed handling library name after "Save as" (was wrong in Description
editor).
- Fixed CHANGE PACKAGE/TECHNOLOGY in case a device contains more than 254
technologies (which was possible due to a missing check in the technology
dialog of the device editor).
- Fixed the technology dialog in the device editor, so that it doesn't
accept more than 254 technologies per package variant.

changes:
SimPy 2.0.1 is a bug-fix release of SimPy 2.0. It
repairs bugs and imperfections in libraries, documentation
and models.
SimPy 2.0 has been a major release of the SimPy simulation
package. It runs on all platforms supporting Python (MS Windows,Linux, Mac).
The major new features of that release are
* an Object Oriented API (in addition to the existing API),
* integration of all documentation into one browsable
and searchable HTML document.
SimPy 2.0 is fully backwards compatible with previous
SimPy versions.
Besides the changes noted below, a major change in 1.6.0 is that the gEDA/gaf suite
is istributed as a single tarball and uses a single build system as opposed to individual
tarballs and builds. In addition to greatly speeding up the build, it is much easier
to maintain. Additionally, it rarely made sense to only install some of the components.
Notable changes in gEDA/gaf 1.6.0
=================================
* Fixed the GtkItemEntry code inside of gattrib code so that it builds
using gtk+ > 2.16.x.
* In gschem, rubberband pin to pin connections by adding nets.
* Cleanup of the slot handling code in libgeda.
* Fixes/updates to the MinGW port.
* Updated the shipped documentation from the online wiki.
Notable changes in gEDA/gaf 1.5.3/1.5.4
=======================================
* NOTE: gEDA/gaf 1.5.3 was released with some critical bugs, so
it was withdrawn before it was widely distributed.
* Text rendering using native system fonts:
- The various programs in gEDA/gaf no longer uses its own built-in
line font.
- Native system fonts are used for rendering, giving support for a
wider range of symbols, and better looking schematics.
* Always use PostScript fonts in gschem's PostScript output. The
"output-text", "text-output" and "output-vector-threshold" config
functions have been removed.
* Image rendering in 'gschem' uses cairo instead of GDK.
* Numerous build system changes:
- gEDA/gaf is now distributed as a single source archive, called
gEDA-<version>.tar.gz.
- GTK+ 2.10 or newer and Guile 1.8 or newer are now required.
- `intltool' is no longer required.
- Documentation is now installed to ${docdir} (usually
${prefix}/share/doc/gEDA).
* The attribute edit dialog in `gschem' now has completion of most
common attribute names.
* The multi-attribute edit dialog in `gschem' now shows unpromoted
symbol attributes.
* Menu items in `gschem' now have icons and properly aligned key
bindings. They also support accelerator keys.
* The `gschem2pcb' and `PCBboard' netlist backends have been removed.
It is recommended to use `gsch2pcb' instead.
* Check for and reject non-footprint PCB files in 'gsch2pcb'.
* Removed unimplemented "File->Open" feature in 'gattrib'.
* Added --disable-gattrib command line flag to ./configure to disable the
building of 'gattrib'. This is useful if you are building against
gtk+ 2.17.x which breaks 'gattrib'.
* 'gnetlist' does not recommend drc2 every time it runs. The drc2
backend is only useful in certain circumstances.
* Assign shortcuts "vd" and "vl" for changing between color schemes
in 'gschem'.
* Fix problem with attached net attribute not being honored in 'gnetlist'.
* Focus the "save" button in the close confirmation dialog in 'gattrib' and
'gschem'.
* Accept empty attributes in the src file in 'tragesym'.
* Cleaned up the slot dialog box in 'gschem'.
* Changed the grip size rendering in 'gschem' to be reasonably sized when
zoomed in a lot.
* Introduction of a new attribute searching API in 'libgeda' and 'gschem'.
* Improvements and cleanup to the 'gnetlist' and 'gsymcheck' test suites.
* Fixed the following bugs:
- 1758673: Combine source tarballs
- 2058707: gschem, gattrib: Dangerous button focus in "Save changes"
dialog at quit
- 2430369: gschem: Deselect invisible attribs with their parent object.
- 2449060: Graphic state left inconsistent cancelling from net mode
- 2460301: libgeda: Make o_complex_promote_attribs() respect keep_invisible
and libgeda: Make o_complex_copy() actually copy.
- 2455061: Gnetlist output changed, and tests fail with recent GLib
- 2655088: autogen.sh: Make sure to exit if autopoint fails.
- 2823703: gnet-pcbpins.scm: Quote pins names if they contain comma
or close parenthesis.
- 2823755: gnetlist: Fix DEBUG builds.
- 2836109: build-sys: Add check for groff html driver.
* Spanish translation were updated.
* Lots of code, infrastructure, and doxygen documentation cleanup and
refactoring.
Notable changes in gEDA/gaf 1.5.2
=================================
* `gschem' now uses Cairo for all rendering. This allows for
everything to be rendered anti-aliased.
* `gschem' now uses a mesh grid instead of dots by default.
* Net junction cues in `gschem' are drawn smaller now.
* Copy and paste now works between different `gschem' instances (using
the X selection).
* Recent files are no longer opened in a new `gschem' window.
* Major, *backwards-incompatible* changes to color handling in
`libgeda' and `gschem'.
- All colors are specified using hexadecimal `#RRGGBB' or
`#RRGGBBAA' syntax.
- The print and display color maps are now separate.
- A new Scheme syntax is used to inspect and modify color maps.
- If you wish to use a light background in `gschem', add the line:
(load (build-path geda-rc-path "gschem-colormap-lightbg"))
to your personal or project gschemrc file.
* Attributes of embedded objects are now shown in the right color.
* Bus pins are now supported by `gschem' and `libgeda', but are *not*
properly supported by the netlister. The pin type can be modified
by selecting a pin, then right-clicking it and selecting `Edit pin
type...'.
* All of the symbols were modified to use overbar markup tags ("like
\_this\_") instead of separate lines.
* Log files are now saved to $HOME/.gEDA/logs rather than being
dropped in the current directory.
Notable changes in gEDA/gaf 1.5.1
=================================
* GTK+ version 2.8.x or later is now required.
* The selection behaviour in `gschem' was changed.
- Lines, unfilled boxes, unfilled circles, arcs, pins, nets, and
buses must be selected by clicking on the drawn path itself.
- Filled boxes, circles, text, and components, may be selected by
clicking anywhere in the bounding box.
- The default mouse click distance required to select an element was
increased to 10 pixels.
- Double-clicking on a net segment selects all connected net
segments.
* The percentage step in or out while zooming the display in `gschem'
is now configurable with the `zoom-gain' gschemrc parameter. The
default value is 20%.
* The size of steps when panning with the mouse wheel or with a
trackpad in `gschem' is now adjustable with the `scrollpan-steps'
gschemrc parameter. The default setting scrolls in steps of 1/8 of
a screen.
* A number of improvements were made to the `gschem' component
selection dialog.
- The dialog now shows a table of top-level attributes in the
selected symbol.
- It is now possible to expand/collapse a library by clicking
anywhere on its row.
* Changes to fill- and line-styles in `gschem' can now be undone.
* Arcs can now be adjusted in `gschem' using an arc angle dialog. It
can be accessed by selecting an arc and selecting Edit->Edit.
* It is now possible to rotate objects while placing them in `gschem'.
* Support for arbitrary filled and unfilled paths, using a subset of
the SVG path syntax. For more information, please see the file
format specification.
<http://geda.seul.org/wiki/geda:file_format_spec>
- `gschem' does not yet provide a GUI for creating or editing path
elements. However, it does support rendering them. They can also
be printed.
- Some of the symbols in the component library were updated to use
paths.
* A Scheme evaluation prompt was added to `gschem'. It can be
accessed by typing `:'.
* Improved algorithm for drawing hatched fills both on screen and in
PostScript output.
* Color selection dialogs and menus in `gschem' now show the actual
color as well as the description. Color names are now translatable.
* `gattrib' now prompts to save changes.
* All of the unimplemented menu items and pages in `gattrib' were
removed.
* The `always-promote-attributes' gafrc parameter now takes a list of
strings as an argument. The space-delimited string syntax is
deprecated.
* Some optimisations were made to the `gnetlist' connection traversal
algorithm to speed up netlisting large designs.
* A new netlist backend was added to support Liquid PCB.
<http://www.liquidpcb.org/>
* The `bom2' netlist backend now generates a `qty' column.
* Several improvements and fixes were made to the `systemc' backend.
* The `--gnetlist-arg' option to gsch2pcb can now be used to pass
extra `gnetlist' arguments.
* `gsch2pcb' now emits files with the latest `pcb' file format.
* The `gxyrs' pick-and-place tool was added.
Notable changes in gEDA/gaf 1.5.0
=================================
* Magnetic net mode in `gschem'. Magnetic mode lets you draw nets and
automatically connect to valid end points (such as pins and other
nets). The `magnetic-net-mode' gschemrc parameter can be used to
enable/disable this feature.
* Rotating a component while moving it in `gschem' now rotates around
the current mouse location.
* The `verilog' and `vhdl' backends now work again.
* Embedded components can now be mirrored.
* The `pads' netlist backend now uses CRLF line endings.

Release Notes for gerbv-2.3.0
========================================================================
The following is a summary of the changes which went into gerbv-2.3.0.
For a complete list of changes, refer to ChangeLog.
- gerbv: fixed a minor arc rendering bug in fast mode
- gerbv: Make the svg/pdf/ps export use a 1:1 scale instead of
scaling to fit the page.
- configure: Always require cairo now since we make use of some of
the transformation functions even when using gdk rendering.
- gerbv: Fix a bug in the vertical scrollbar calculations.
- libgerbv: Fix a bug where apertures < 10 were potentially ignored in
some drill files
- gerbv: Fix clipping bug when viewing files with image offsets
- gerbv: Fix a bug whereclicking on the message tab caused the keyboard
accelerators stop working
- gerbv: Use a reasonable return code when doing command line processing.
- libgerbv: Improve the macro parser.
- libgerbv: Allow 0 degree rotation
- libgerbv: Fix some drill parser bugs
- libgerbv: Support the Excellon "R" (repeat) command
- testsuite: Add some tests for drill files
- libgerbv: Fix a bug in the Excellon export which sometimes dropped the first
element.
- libgerbv: Fix some additional Excellon export bugs.
- gerbv: Add the ability to rotate/translate layers
- libgerbv: Fix the pkgconfig file to include some needed dependencies.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Release Notes for Icarus Verilog 0.8.4
This is a bug-fix release for the 0.8 stable branch. The 0.8 stable
branch updates do not include significant new features (they go into
the devel branch instead) nor fixes that are deemed to drastic to
include in a stable tool.
- Various source code portability problems have been fixed. The 0.8 no
longer compiles on many modern systems.
- Various bug reports have been put to rest with this release. Some
parser errors have been fixed (including a few regressions from
0.8.3) and a few new syntaxes added.
- A variety of systhesis bug fixes and enhancements are included in
0.8.4. Currently, synthesis is only actively supported in the 0.8
branch, and the 0.8.4 is the most complete.

========================================================================
Release Notes for PCB snapshot 20081128
========================================================================
This release represents over 70 commits and as such this summary
clearly is not complete. See the ChangeLog file for the complete list
of changes.
- Minor bug fixes in RS274-X output.
- Bug fixes in postscript output
- DRC checks for annular ring on pads only uses the mininum annular ring
drc setting instead of also checking minimum copper width.
- Fix postscript output for zero length lines.
- Improve the 'save before closing' dialogs.
- Fixed bugs where objects attached to the cursor vanish sometimes.
- Various minor code portability improvements.
- Enabled additional gcc warnings (when using gcc)
- Allow outline layers to have only arcs.
- Added "Ben Mode" png output which provides a simulated "photograph"
of the board. Very nice for publications.
- Fix poly clearance around rotated pads.
- Fix the batch HID which had bit rotted a little.
- Display net names hierarchically.
- Various speed improvements in the GTK HID.
- Various speed improvements in the autorouter.
- Minor improvements to the windows port.
- Other various bug fixes.
Don't call pkg_info to get the installed Emacs version; always use the
version matching EMACS_TYPE set by users. Be DEPENDS to it. This should
address pkg/37146 by Aleksey Cheusov.
While here convert some emacs lisp packages to user-destdir.
* Added ability to select objects, with the option of deleting or viewing
basic properties of the objects
* Split off the core functionality of gerbv into a library (libgerbv) to
allow developers to quickly write software using Gerber
parsing/editing/exporting/rendering functionality. Full DOxygen
documentation has also been created to facilitate developers wishing to use
libgerbv.
* Added export to RS274X and Excellon functionality, allowing gerbv to
translate files between formats. The RS274X export function can also be
used to "clean" troublesome files to a more compatible format.
* Added the ability to override the Excellon format "guessing", allowing
non-standard drill files to be correctly rendered
* Greatly expanded the command line functionality, including the ability to
panelize boards into a single one through the command line
* Added "Aperture usage" tab to Gerber reports. This allows the user to
see how often each aperture is used in all visible layers of his project.
Several notable bugs were squished in release 2.1.0:
* Fixed bug when exporting several layers to SVG/PDF/PS, which caused
corrupted output and/or crashes
* Fixed several Windows-only problems related to parsing and rendering
* Fixed rendering bug when using polygon objects within step and repeat
blocks
* Improved RS-274X export output format to work with certain Gerber viewing
software
patches to add it). Drop pax from the default USE_TOOLS list.
Make bsdtar the default for those places that wanted gtar to extract
long links etc, as bsdtar can be built of the tree.
- assume that Python 2.4 and 2.5 are compatible and allow checking for
fallout.
- remove PYTHON_VERSIONS_COMPATIBLE that are obsoleted by the 2.3+
default. Modify the others to deal with the removals.
Also, do not install calcCAP or calcRL. These two tools seem to give
results of questionable accuracy (see the sourceforge bug tracker
for the upstream sources) and also don't build with gcc-4 anyway.
Bump pkgrevision.
Many updates including
- 100% of RS274-X is now supported
- cairo rendering which among other things gives printing to a printer, pdf,
png, ps, or svg.
- gnome/kde desktop integration
- added a regression test suite
- lots of rework of the gui.
All in all this is a major overhaul.

Notes/Bugs/Errata/Known Issues/Last Minute Issues
__________________________________________________________________
* Many thanks to everybody who contributed to this snapshot and
previous development snapshots.
* Updates to this stable snapshot (1.4.x series) will occur if people
find issues.
* The next major stable snapshot (1.6.x) will probably happen in the
middle of this year.
* Please submit all bugs to the [3]bug tracker.
This release represents a point release incorporating a few patches made
against the 1.0.X source over the last 1 1/2 years. Specific updates
include:
* Incorporate changes from Joost Witteveen to support extended
%SR% commands.
* Fix endless loop bug when gerbv encountered an unknown
% code. Patch from Joost Witteveen.
* Fixed initial scale setting for %MOMM% Gerber files.
Patch from Joost Witteveen.
* Fixed format for small drillfiles. Patch from Trevor Blackwell.
* Fix setting of the initial window size when the screen
is larger than the display. Patch from David Carr.
Most of the previous pkgsrc patches have been incorporated upstream (yay!).
New in 20060606
- ??
New in 20051222
- full-height vertical scrollbar appears if the total height of all
panels becomes larger than the window.
- new panel type "jumbo" stays larger even when things get crowded
- most deprecated guile calls removed. Guile 1.6 or later is now required.
New in 20050928
- ALPHA RELEASE: may crash. do not rely on for production use.
- handling of multi-sweep datafiles
- vertical scrollbars on label/measure area in each wavepanel make handling
large numbers of waveforms easier.
New in 20031202
- Got docstring extraction from C source to .txt files in doc directory working again
- applied submitted patch that cleans up warnings from gcc3 about multiline text strings in C code
New in 20030917
- bugfixes to make the new print/plot stuff work better
- path to working gnu graph found by configure is passed to scheme code
then automatically generate a PLIST that says "${PKGNAME} has no files".
* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
and no PLIST files exist, then fail during the package build with
PKG_FAIL_REASON.
* Remove "intentionally empty" PLISTs again.
Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:
PLIST_SRC= # empty
that directly manipulate empty PLISTs.
Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.
There are a large number of changes in this update. Many bugs have been fixed,
VCD writing has been improved, the build system has migrated to a fully
autoconf/automake system from a partial gnu system.
The code written as part of the 2007 Google summer of code has been incorporated
which allows waveform reloading and provides the framework for further enhancements.
For the complete set of changes, see CHANGELOG.TXT in the distribution file.

Release Notes for PCB snapshot 20070912
========================================================================
This release represents nearly 200 commits and as such this summary
clearly is not complete. See the ChangeLog file for the complete list
of changes.
- Many many bug fixes. Too many to list.
- Added keystone, C&K, Nichicon, and Optek footprint libraries
- Add attribute editor to the GTK HID
- Add a fileselect() function to the HID spec
- Fix ps output with drill helper on
- Add a visual indicater when elements are locked
- Corrections to the manual
- BOM can export in mm as well as mil
- Fix a ps output bug with arcs
- Fix some memory leaks found with Coverity
- Added autoconf test for buggy versions of m4
- Fixed some footprint drill sizes
- Add user customizable menus for the gtk HID. The gtk HID now is capable
of reading the same format menu resource files as the lesstif HID.
This represents significant rework of the menu code and menu callback code.
- Added Center() action
- Store the file format in the .pcb file. This will let pcb know when
presented with a file which is too new. The code for checking the format
was present in the prior snapshot.
- Fix DRC checking of square pads to square pads
- Added window panning/cursor warping
- Add the ability to directly load a footprint from a file as if it were
a complete layout.
- Add a Popup() action
of an emulated operating system. Instead of proliferating things like
SUSE_VERSION_REQD, NETBSD_VERSION_REQD, SOLARIS_VERSION_REQD, etc., a
package can say:
EMUL_REQD= suse>=9.1 netbsd>=2.0 solaris>=10
all in one, succinct line.
binary-only packages that require binary "emulation" on the native
operating system. Please see pkgsrc/mk/emulator/README for more
details.
* Teach the plist framework to automatically use any existing
PLIST.${EMUL_PLATFORM} as part of the default PLIST_SRC definition.
* Convert all of the binary-only packages in pkgsrc to use the
emulator framework. Most of them have been tested to install and
deinstall correctly. This involves the following cleanup actions:
* Remove use of custom PLIST code and use PLIST.${EMUL_PLATFORM}
more consistently.
* Simplify packages by using default INSTALL and DEINSTALL scripts
instead of custom INSTALL/DEINSTALL code.
* Remove "SUSE_COMPAT32" and "PKG_OPTIONS.suse" from pkgsrc.
Packages only need to state exactly which emulations they support,
and the framework handles any i386-on-x86_64 or sparc-on-sparc64
uses.
* Remove "USE_NATIVE_LINUX" from pkgsrc. The framework will
automatically detect when the package is installing on Linux.
Specific changes to packages include:
* Bump the PKGREVISIONs for all of the suse100* and suse91* packages
due to changes in the +INSTALL/+DEINSTALL scripts used in all
of the packages.
* Remove pkgsrc/emulators/suse_linux, which is unused by any
packages.
* cad/lc -- remove custom code to create the distinfo file for
all supported platforms; just use "emul-fetch" and "emul-distinfo"
instead.
* lang/Cg-compiler -- install the shared libraries under ${EMULDIR}
instead of ${PREFIX}/lib so that compiled programs will find
the shared libraries.
* mail/thunderbird-bin-nightly -- update to latest binary
distributions for supported platforms.
* multimedia/ns-flash -- update Linux version to 9.0.48 as the
older version is no longer available for interactive fetch.
* security/uvscan -- set LD_LIBRARY_PATH explicitly so that
it's not necessary to install library symlinks into
${EMULDIR}/usr/local/lib.
* www/firefox-bin-flash -- update Linux version to 9.0.48 as the
older version is no longer available for interactive fetch.
Release notes for the gEDA/gaf 20070526 snapshot
Changes
_________________________________________________________________
libgeda/gschem
* libgeda's shared library version is now 29:0:0.
* Added "recently used files" File menu option. Now you can open up
files you used recently (and if you have a gafrc your components
should be found too) and open those files up in a new gschem
window. (Ivan Stankovic)
* Merge of the noscreen branch (many changes). This branch removed
all cached screen coordinates. Now all calculations are done in
world coordinates and should yield some drawing improvements. End
users should not notice any difference (other than the slight
speed up). (Peter Clifton)
* Many improvements to the "Write image..." dialog box in gschem.
gschem can now export any image that gtk+ (gdk-pixbuf
specifically) can write (png, jpg, ico, bmp, etc...). Libgd is no
longer an optional dependency and cannot be used with
libgeda/gschem. (Carlos Nieves Onega)
* Improved the auto placing mechanism. One improvement (amongst
others) is in the cases of: if the attribute overlap with pins
(including pinnumbers), or the pin connection direction where a
net is supposed to be drawn, then the attributes are moved
automatically. (Carlos Nieves Onega)
* A few improvements to the component place selector including
adding ok button to hide the component insert dialog box).
(Various)
* Added items (links to the wiki and FAQ) to the gschem help menu.
(Peter Brett)
* Fixed a nasty bug that was causing random crashes with keymaps
that did not have a valid keyval/keysym. (Peter Clifton)
* Fixed the drawing of dotted arcs/circles when the dot spacing is
too small to render. (Peter Clifton)
* Fixed component selector filter to be case insensitive. (Carlos
Nieves Onega)
* Added PageUp and PageDown hotkeys to change pages in gschem.
(Peter Brett)
* Fixed the ordering of buttons in all gtk dialog boxes to be
correct (based on what gtk+/gnome/desktop conventions). (Carlos
Nieves Onega)
* Added %%Orientation to DSC block in postscript output. (Mike
Jarabek)
* Fixed color printing of select objects (should not output the
selected color). (Peter Clifton)
* Added hotkeys to decrease and increase the snap grid spacing.
(Carlos Nieves Onega and Peter Brett)
* Improved keymap filling routines (Werner Hoch and Patrick Bernaud)
* Fixed a couple of small memory leaks. (Ales Hvezda)
* The usual slew of bug fixes by many individuals.
* A bunch of code cleanup/fixes by various individuals.
* Various language translations updated by various individuals.
gnetlist
* New gnetlist backends written: Calay and Osmond. (John Doty)
* Moved the loading of scheme files using the "-l" command line
before the schematics are loaded (this allows the scheme code to
modify the various search paths).
* Various improvements to the spice-sdb backend including the
treatment of slotted parts (so that pins are emitted in pinseq
order). (Stuart Brorson)
* Added and improved a bunch of regression tests. The vast majority
of these tests are now run during make distcheck. (Stuart Brorson
and Ales Hvezda)
* A few bugs fixed. (Various)
gattrib
* Added doxygen generated docs. (Stuart Brorson)
* A bunch of bugs fixed. (Stuart Brorson and Peter Clifton)
docs
* Removed the html version of the gsch2pcb tutorial. Instead, the
gsch2pcb tutorial is now part of the wiki thanks to several
individuals (Patrick Doyle and Bogdan Petrisor).
* Updated the wiki snapshot to the latest web wiki version. (Ales
Hvezda)
* Misc improvements to various wiki scripts. (Ales Hvezda)
symbols
* Added greek mu character. (Carlos Nieves Onega)
* Added upper case greek omega character. (Jens Persson)
gsymcheck
* No significant changes.
utils
* Added refdes_renum test suite. (Dan McMahill and Stuart Brorson)
* Incorporated --gentle into refdes_renum which doesn't overwrite
refdes'es already numbered. (Stuart Brorson)
* Moved gschemdoc to the gschem package. Bunch of improvements to
the gschemdoc script related to finding local/remote
documentation. (Carlos Nieves Onega)
examples
* Fixed automake infrastructure to install 2N3904 model for the
TwoStageAmp example. (Stuart Brorson)

Nelma is a (command line) tool for numerically calculating various
electrical properties of printed circuit boards or similar objects
composed of conductors and dielectrics (however code is optimized for
circuit board-like geometry).
It is currently capable of calculating capacitances between objects -
nets on a PCB. It returns a spice-compatible description of an
equivalent circuit of stray capacitances that can be for example used
for more accurate circuit simulation. Alternatively it can also
produce field data that can be plotted for example with Gnuplot.
Support for calculating resistances existed for a while but was later
removed because it didn't receive much testing.
Nelma is available under the GNU General Public License version 2.
Release Notes for Icarus Verilog Snapshot 20070227

* Various spelling fixes.
LC is simulation tool for the analysis of the electromagnetic
properties of electrical interconnects. The full three-dimensional
circuit is modeled, so all interactions are automatically included in
the solution. The model can be excited by numerous types of waveforms,
and the transient response measured using common values such as
voltage and current. Circuit parameters such as inductance,
capacitance, and impedance can be derived from the transient response,
and frequency-domain results such as S-parameters can also be
calculated. Far field radiation patterns can be obtained.
LC is primarily an electromagnetic simulation and uses the
Finite-Difference Time-Domain (FD-TD) technique. FD-TD is a full wave
explicit solution of Maxwell's equations in three dimensions. In FD-TD,
the rectangular volume enclosing the model is discretized into a large
number of small cells, which may be uniformly-sized, or may vary in size
within the simulation space. The dielectric, permeable, lossy, and
conducting material properties of each cell are incorporated into the
field updates, which are performed iteratively in small time steps.
An interface between the electromagnetic simulation and the circuit
simulation program SPICE is available within LC. This allows the user
to add arbitrary SPICE circuits, such as drivers and loads, into the
interconnect model. The interconnect performance is calculated using
FD-TD while the lumped-element circuits are evaluated by SPICE.
Release Note for Icarus Verilog Snapshot 20070123
Handling of arrays has been rewritten to allow support for net
arrays. This caused ivl_target API changes, as well as elaboration and
vvp run time changes. There may be bits of the old method lingering in
the source code.
Improve support for constant power (**) expressions, and other
constant exppressions that are passed to functions/tasks.
Improve elaboration of for-loop increment expressions. There were some
bugs there that are not fixed.
Fix argument width calculations for shift operations.
Constant ector expressions can have real constants. Handle this at run
time where needed.
Fix some bad lookaside optimizations for assignments to l-value part
selects.

SimPy 1.8 is a major release with new capabilities, improved documentation
and bug fixes. It is fully backwards compatible with previous versions.
From SimPy 1.8 on, the obsolete Python version 2.2 is no longer supported.
Some of the changes and improvements are:
* New compound yield statements, supporting time-out or event-based
reneging in 'get' and 'put' operations on Store and Level resources.
* yield get on a Store resource can now have a filter function which
selects which and how many items (e.g. "3 parcels weighing less than
3 pounds") should be retrieved.
* The Manual has been thoroughly edited, restructured and rewritten
with a view to greater clarity and readability. It is provided in both
HTML and PDF format.
* The Cheatsheet has been completely rewritten in a tabular format and
reduced to just a few pages. The goal was to turn it into a concise
desktop reference of SimPy commands. The Cheatsheet is provided in both
XLS (MS Excel spreadsheet) and PDF format.
SimPy 1.7.1 is a minor (maintenance) release which fixes a few bugs
in 1.7. The SimPy 1.7.1 API is identical to that of version 1.7.
SimPy 1.7 is fully compatible with version 1.6.1. This major release brings
significant new capabilities for the SimPy modeller and thus a broader
field of applicability to SimPy. It is now very easy to implement models
for scenarios involving:
* producer/consumer relationships between processes,
* multi-process cooperations,
* multi-resource requests, and
* consumable resources.
Error: An integer constant expression is required within the array subscript operator.

Changes
_________________________________________________________________
libgeda/gschem
libgeda and gschem no longer use libgdgeda (which was a gEDA specific
hack to the libgd library). gEDA/gaf now wants to use the original
GD library. (Wojciech Kazubski and Carlos Nieves Onega with
cleanup by others)

better than the original one. Please test it out and submit
comments to the mailing lists. (Patrick Bernaud)
* The preview window is inside the file selectors again. The preview
window has been refactored and improved. (Patrick Bernaud)
* gschem now places a title block (or any component the user wants)
when a new page/window is created. This solves the common complain
that the initial zoom is way to far out. (Carlos Nieves Onega)
* Improvements to the new print dialog box: Make print settings
sticky for session. (Peter Brett)
* Fixed bug #1527465: Do a zoom extents for all pages when the main
window is maximized. (Carlos Nieves Onega and others)
* Fixed bug #1565433: Added the border in the gdk-pixbuf's image
output. (Carlos Nieves Onega)

gsymcheck
* Adds newline that is missing from the "Found Pintype=..." message
in s_check_pintype() in s_check.c. (Jeff Mallatt and Carlos Nieves
Onega)
* gsymcheck now counts the number of distinct pinnumbers specified
in all slotdef= attributes. Uses that number, plus the number of
net= pins, to compare with the "footprint size" when checking for
that warning. (Jeff Mallatt and Carlos Nieves Onega).
utils
* Applied patches for the cygwin port. Lots of various improvements
to make gschemdoc more Windows friendly (at least under cygwin).

Development release covered-20060904 made. This is primarily an enhanced language support release
containing support for the Verilog-2001 'generate' block and support for some SystemVerilog constructs.
All bug fixes from the stable release branch have also been included in this release as well. Some
updates to the GUI (to match changes made on the score command side). The following is a list of
changes made from the last development release
- Complete parsing/simulation support for generate blocks include generate for, if/else and
case constructs.
- Fixed bug in hierarchically referencing items within an array of instances.
- Added -g option to score command to allow the user to specify on either a global or modular
level which Verilog generation to consider for that design. This allows a block of logic written
with Verilog-1995 in mind to use names that would be keywords in Verilog-2001 or SystemVerilog,
as an example.
- Removed "manstyle" type documentation in user's guide as this tool is no longer used for this
project. This change should be transparent to the user, however.
- Fixed scoping/hierarchical referencing rules to match the Verilog LRM properly.
- Added parsing/handling support for SystemVerilog always_comb, always_ff and always_latch blocks.
- Added parsing support for 'unique' and 'priority' SystemVerilog keywords before if and case
statements (Covered doesn't need to do anything with them, however).
- Added parsing/handling support for 'do .. while' SystemVerilog loops.
- Added parsing/handling support for new SystemVerilog data types, including: byte, bit, logic,
char, shorting, int and longint.
- Added -rI option to the score command which allows the user to completely bypass the race
condition checking phase of the score command.
- Added -B global option which obfuscates all identifying names from Covered's output (for use
in providing debugging information to the developer's of Covered).
- Added parsing/handling support for operate-and-assign SystemVerilog operators, including:
+=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=, <<<=, >>>=, ++ and --. These can be used wherever
their counterparts can be used (including generate for loops).
- Added proper handling of Verilog-1995 delayed blocking assignments (i.e., "a = #5 b;" or
"a = @(posedge clk) c;"). Previously, the delay was being incorrectly ignored which could
have lead to infinite looping of always/forever blocks or could calculate incorrect coverage
information.
- Added parsing support for SystemVerilog .name and .* port lists.
- Added partial parsing/handling support for SystemVerilog 'typedef' usage. This should work for
enumerations but not other data types at this point.
- Added parsing/handling support for SystemVerilog 'enum' constructs. These should be fully
supported with the exception of their built-in '.first', '.last', '.next', '.prev', '.num' and
'.name' methods.
- Added full support of handling Verilog-1995 repeated delay blocking assignments (i.e.,
"a = repeat(5) @(posedge clk) b;". These were previously being treated as normal blocking
assignments.
- Added keyword highlighting support in GUI for Verilog-2001 and SystemVerilog keywords depending
on the -g value specified for a particular module.
- Added parsing support for SystemVerilog assertion, property and sequence blocks. These constructs
are ignored by the parser but should not cause a parsing error now.
- Added parsing support for SystemVerilog multi-dimensional arrays. These are ignored by the
parser but should not cause an error.
- Added full support for the SystemVerilog $root global space -- though limited testing has
been performed with this at this point.
- Added -s option to the report command to suppress the output for modules/instances that contain
no coverage information.
- Updated all user documentation to match changes made for this development release.
- Lots of new diagnostics added to regression suite to verify the majority of these changes.
There you have it. A lot of enhancements made for language support for Verilog-1995, Verilog-2001
and SystemVerilog. Some of the additions for SystemVerilog, especially typedefs and $root global
space, have not been fully verified to work and may still be a bit buggy, but everything else should
be expected to work as advertised. Please submit any bugs that you find. The next development
release should contain support for some more language enhancements, including full support for
typedef and enumeration usage, support for memories, multi-dimensional arrays, structs and unions.
I will also be looking at adding support for bitwise coverage information (for vectored calculations).
As always, have fun!
* 08/30/2006
Stable release covered-0.4.7 made. This release is mostly a bug fix release with two feature
additions. The new feature is the global -B option was performs name obfuscation on all identifying,
design-sensitive names from all output (with the exception of CDD file output). This option is
mostly useful as a way to share debugging information with the maintainer(s) of Covered without giving
away sensitive information. Additionally, the -rI score option was added to allow user's to completely
skip the race condition checking phase. This allows users to force Covered to consider all code for
coverage (if race condition checking is performed, all code considered to be potential race conditions
are automatically excluded from coverage consideration). User documentation has been updated for these
changes. The following lists the changes in this release.
- Fixed bug 1535412. Implicit event expressions (i.e., "always @*") now traverse named begin/end
blocks correctly to search for RHS variables.
- Fixed bugs related to segmentation faults and memory leak issues
- Fixed hierarchical reference search to match Verilog-1995 LRM
- Fixed bug 1538922. If -vcd or -lxt option was specified twice, an incorrect error message was
displayed to the user.
- Added -rI option to allow user's to bypass the race condition checking step in the score command.
- Fixed bug 1538920. Handling of any-edge triggered events (i.e., "@(b)") was incorrectly handled
by Covered. Additionally, fixed the event trigger operator (->) to work correctly with the new
changes.
- Fixed bug 1541944. Command options that require a value are now checked to make sure that a value
exists, and an appropriate error message is output if this is not achieved.
- Fixed bug 1542454. Command options that must only be allowed once on a command-line are now
checked and handled appropriately (caused a segmentation fault previously).
- Fixed bug 1544322. When an AND- or OR-type expression has either a left or right expression evaluate
to 0 or 1, respectively, Covered now outputs correct coverage information when the opposite expression
evaluates to an X or Z value, simultaneously.
- Fixed bug 1544325. Multi-variable expressions are now always output as such in report files.
- Fixed bug 1544169. Avoiding consideration of named begin/end block keywords in line coverage.
- Fixed bug 1546059. Covered now properly handles the removal of statement blocks that cannot be
considered for coverage which also contain parameters from another functional unit block.
- Fixed bug with connection of statements in a statement block.
- Updated documentation to match new features added in this release.
* 07/22/2006
Stable release covered-0.4.6 made. This release contains several bug fixes that are listed below.
- Fixed segmentation fault bug which occurs when a multi-bit select on the LHS contains any
expression besides static values.
- Fixed several memory leaks found with valgrind
- Fixed bug 1520159 - arrays of instances incorrectly always started at index 0.
- Fixed bug 1521598 having to do with reduction unary invert and logical not operators not
calculating correctly.
- Fixed bug in db_read when a functional unit is being merged to point to the used module.
- Fixed assertion in link.c such that no segmentation fault occurs if a string is not found
in a str_link list for deletion.
- Fixed bug pertaining to embedded concatenations within function/task parameter lists.
- Fixed bug pertaining to empty named begin-end blocks.
- Fixed bug in the db_read function that would cause Covered to flag an internal assertion
error if an error occurred while reading the CDD file and the global -D option was specified.
- Fixed upwards name referencing bug (1524705).
- Enhanced regression suite to verify that all of these bugs are properly fixed.
* 07/08/2006
Stable release covered-0.4.5 made. This release contains a bug fix to properly handle cases
where two or more signals are declared with a parameter in their range field (i.e., reg [FOO:0] a, b;)
This caused Covered to segfault due to attempting to free the same address twice. Bug 1518932.
Also contains a bug fix to properly remove statement blocks that contain case, casex or casez
expressions and unbindable expressions.
* 5/28/2006
Stable release covered-0.4.4 made. This release contains a bug fix to proper handle hierarchical
referencing of parameter values. This feature was technically not supported in the past but caused
an internal assertion error when this was performed. The feature is now fully supported.
* 4/21/2006
Stable release covered-0.4.3 made. This release contains a bug fix to the statement connection function that
caused segmentation faults during the score command. Also added support for big endian wires/regs. This
information was being ignored by the parser and, consequently, was not being handled correctly by Covered's
internal simulator, leading to incorrect coverage information. The lack of this support was also causing
an internal error in the memory allocation routine when scoring the dumpfile.
* 4/17/2006
Stable release covered-0.4.2 made. This release contains a bug fix that caused an assertion error in the
binding.c source file to occur. The reason for this assertion was a syntax error in the parser that caused
problems when more than one task call was made in a statement block. Also added support for multi-line
definitions (i.e., a '\' character used at the end of a definition line). This was missing but was not meant
to be missing.
* 4/4/2006
Stable release covered-0.4.1 made. This release contains one bug fix that causes an assertion error when
compiling designs that use a concatenation operation on the left-hand-side of assignment statements. If
you are experiencing this problem with the 0.4 release, it is recommended that you use this new release
instead.
* 3/29/2006
Stable release covered-0.4 made. In addition to all of the features, optimizations and bug fixes
that have gone into the development releases from the 0.3 stable release, the following features, updates
and bug fixes have been added.
- Fixed bug with a statement connection issue that causes lines of code to be not considered for
coverage that should have been.
- Fixed bug in report command where combinational expressions were not being output to match the original
Verilog code.
- Added CDD file viewer window to GUI to allow the user to see which CDD files are currently loaded/merged.
- Fixed bug in combinational logic verbose viewer which caused the window to resize dependent upon
the location of the cursor (this was an annoyance)
- Changed the output of simple combinational logic to change to unary combinational logic output if either
the left or the right expression was a constant value (eliminates unachievable combinational logic cases
from being output leading to more accurate coverage results).
- Removed combinational expressions that contain only constant values from being considered for coverage.
- Updated simple combinational logic output in reports to be as concise as possible for AND and OR type
expressions.
- Removed duplication of information in CDD files for race conditions.
- Fixed bug in GUI dealing with showing race conditions
- Fixing bug in GUI pertaining to the next/previous buttons in the combinational logic detail viewer. Previously,
clicking on one of these buttons would only advance you to the next uncovered line. Now it will advance
you to the next uncovered statement.
- Updated development, user and GUI documentation to reflect the above changes and to bring them up-to-date
with the rest of the tool.
Please see the ChangeLog file for all changes made from the 0.3 stable release to the 0.4 stable release.
Lots of enhancements, features, optimizations, bug fixes, performance improvements and documentation improvements
are contained in this stable release, making it very worth while for any Covered users to get their hands on
it.
* Release Notes for Icarus Verilog Snapshot 20061009
The Big news is support for delay path timing is specify blocks. This
includes delay paths and specparams. Back annotation of specify path
timings are not yet implemented.
The "-g" flag has been made a bit more general so that individual
compiler features can be turned on/off. This for example allows for
turning off specify block support and Icarus Verilog extensions, as
well as select language generation.
A variety of bug fixes have been included.
- Missing symbols on Windows fixed.
- mingw build instructions reworked.
- Fix internal handling of -D__ICARUS__ define
- Fix crash of driver when -M flag is used.
- Fix configure detection of host in some subdirectories.
- Handle non-constant delays of index non-blocking assignments.
- $scanf support for real values.
- Fix scheduling of RWsync vs. ROSync callbacks.
- Fix vpi_put_userdata return value.
The iverilog-vpi command now allows .cpp files to stand for C++
source.
** Release Notes for Icarus Verilog 0.8.3
This is a new release of the stable 0.8 branch. The changes from 0.8.2
are intended to be evolutionary, rather then revolutionary, to enhance
the stability of the branch.
Various simulator bugs have been fixed, including (but not limited to):
- Detect overrun of timescale vs. precision
- Handle more operators in constant expressions
- Various ivl crashes and panics fixed.
- Some performance bottlenecks have been fixed.
- Various tool compilation problems have been fixed.
Also, the internal synthesizer (for synthesis targets) has been
considerably improved. NOTE that the code generators have not been
improved to take advantage of all the changes here, so there is work
yet to be done.
The mingw build process for compiling in Windows has been reworked. It
is now possible (indeed preferable) to compile fully native Icarus
Verilog binaries on Windows with no Cygwin tools at all.

gEDA/gaf for a while. Mixing malloc/free and g_malloc/g_free is a
bad idea and also setting a field in deallocated memory tends to
upset glib's memory management.
* Added a new rc variable called "always-promote-attributes" that
takes a string of attribute names that are automatically prompted
when a component is placed on a schematic. The default list is:
"footprint device value model-name".
* Newly rewritten postscript output to be much more compact, sane.

report any more crashes.
* Fixed component update to work correctly since it was looking for
existing attributes in the wrong places.
* Converted all the noweb code to just plain C (making sure that all

docs
* Obsoleted all latex documentation and replaced it with a snaphot
of the gEDA wiki. Many thanks to David Hart for the conversion and
necessary support to make this conversion possible.
examples
* No significant changes.
misc
* The geda (gManager) source tarball is not longer being
distributed. All the code is still in the CVS repository, but due
to lack of maintanance, it has been pulled for these snapshot
releases.
* Fixed various Makefiles to support make distcheck again.
* Lots of bug fixes by (Werner Hoch, Carlos Nieves Onega, and many
others).
For more a detailed changes, please look in the appropriate ChangeLogs
in the source tarballs.

last packaged snapshot. Those are:
--------------------------------------------------
Release Notes for Icarus Verilog Snapshot 20060215
--------------------------------------------------
* Part select of memory words should now work according to
Verilog-2001. This also led to some cleanup of the handling of types
internally, as well as some infrastructure for general arrays.
* Minor fix to parsing of (* *) attributes.
* Fix rounding of reals to integers.
* Clean up some of the vvp engine related to memories. Remove some
dead instructions.
--------------------------------------------------
Release Notes for Icarus Verilog Snapshot 20060409
--------------------------------------------------
the most substantial difference in this snapshot the first signs of
generate support. The compiler now supports generate loops and has
been tested with examples that include wires and gates within the
generate scheme. The regression test suite has very few generate
tests, so any concise self-testing test programs that use generate
would be helpful.
Also, instance arrays that use overridden parameters now work
properly.
Task arguments are a bit more flexible in order to support vendor
(notably Xilinx) models that use more interesting task arguments.
Runtime support for bi-directional ports had some bugs fixed, along
with some other minor run-time bugs. Also, the runtime gains support
for typed parameters. And also, there are some new runtime callbacks
for events and memories.
Parameters had a few types related bugs fixed. They are a bit more
flexible now.
And various minor compilation errors have been fixed. This includes
C/C++ compilation errors fixes, and some configure/Makefile tweaks.
--------------------------------------------------
Release Notes for Icarus Verilog Snapshot 20060618
--------------------------------------------------
Add support for system functions in continuous assignments.
Allow concatenations as arguments to inout ports. This comes with a
small variety of internal part select and concatenation bug fixes.
Fix some bugs in constant propagation through ternary expressions.
Fix broken subtraction if small constants in certain cases.
Fix a few datatype mismatch errors.
Make $readmem give warning when input is inadequate for requested
range.
Fix runtime of nand in continuous assignments.
Fix synchronous user defined primiteves to only follow edges.
Fix a runtime error in some thread delays processing.
Improve limited genvar expression handling.
Start a rework of expression elaboration. Make elaboration aware of
the expression context width when appropriate in order to better
handle expression width and padding.
Fix the make rules for parse.cc to reflect that they come from the
same source. Fix the autoconf.sh to configure the stub target.
Fix portability of the lexor source files on Windows systems. Get rid
of the isatty references.
Make a stub lround when the system version is missing.
--------------------------------------------------
* Release Notes for Snapshot 20060809
--------------------------------------------------
Some handling of real values is improved. Real valued literals are
handled in net contexts (continuous assignment, etc.). Also, modulus
of real operands now works. (This is an extension to the Verilog
standard.)
The power operator (**) now works.
Signed right shift works properly now.
The $sscanf and $fscanf are introduced, and work at least for basic
numeric values.
The release function now works to undo general force statements, and
not just contant force statements.
Delay constants up to 64 bits are supported. This at first doesn't
seem like an issue, but when precisions are mixed, it becomes
surprisingly easy to overflow 32bit delays.
The driver is reworked to pass many preprocessor details through a
temporary file instead of on the command line of a system(3)
call. This prevents confusing and incorrect shell processing of
complex strings passed as values to -D flags.
Various other little fixes.
Changes are:
* Removed all build support for GTK1.
* Dino Ghilardi fixed log.c (the last reminder of GTK1) so
log windows popup don't crash gerbv anymore.
* Dan McMahill added the GCC4 patch.
* Renamed stack_t to macro_stack_t to support darwin/MacOS X
pointed out by Daniel Mack.
* Changed build system to suit new autoconf/automake versions.
Caused gerbv not to find init.scm.
* Fixed a bug so gerbv can handle negative coordinates when using
trailing zeroes.
* Better checking of return values for errors.
* Use setlocale explicit so your locale doesn't screw up sscanf
and strtod to use comma (,) instead of dot (.).
* For distributions there is a new directory called desktop, where
gerbv.desktop and gerbv.png is stored for desktop settings.
Submitted to Debian bug list from Vassilis Pandis for Ubuntu.
since they always need a C compiler, even when the source code is
completely in C++.
For some other packages, stated in the comment that a C compiler is
really not needed.
had actually been ignoring LTCONFIG_OVERRIDE anyway and just using
the default LIBTOOL_OVERRIDE to replace libtool scripts in packages.
This just formalizes the fact that LTCONFIG_OVERRIDE is not used
meaningfully by pkgsrc.
Many improvements since the last packaged version including, but not limited
to:
- enhanced transient timestep control algorithm which is significantly more
accurate than spice now.
- enhanced compatibility with hspice netlists
- named nodes (as opposed to numbered only nodes) work now
- improvements to the bsim3v3 model support
- migration from a custom build system to a GNU autoconf/automake based build
system.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
