KiCad 5.1.2 Release
2019-04-26
The KiCad project is proud to announce the latest series 5 stable release of KiCad. The 5.1.2 stable version contains critical bug fixes and other minor improvements since the 5.1.0 release. It also includes improved footprint, symbol, and 3D model libraries, translations, and documentation. A list of all of the fixed bugs since the 5.1.0 release can be found on the KiCad 5.1.2 milestone page. This release contains several critical bug fixes so please consider upgrading as soon as possible.
KiCad 5.1.0 Release
2019-03-14
The KiCad project is proud to announce the release of version
5.1.0. This is the first ever minor version release of KiCad and was
developed primarily to resolve compatibility issues with Linux GTK3
and long awaited support for python3.
In addition to the primary focus, there have been many important
changes that make this release a substantial improvement over the 5.0
series and a worthwhile upgrade for users on all platforms. Included
in the improvements are:
- Improved 3D model library path configuration.
- Cairo canvas is now used for printing support on all platforms.
- Schematic and symbol library editors now use the modern canvases for
rendering.
- Symbol pin table is now editable.
- Pcbnew scripting support for Python 3 has been added.
- Snapping for graphical object drawing in board and footprint editors.
- Significant user interface improvements.
- Major dialog box improvements.
- Both the footprint and symbol library editors now share the same
user interface paradigm with a library tree view pane.
- Symbol, footprint, and 3D model library improvements.
- Documentation and translation improvements.
- Less pain for Linux package maintainers, now all features should be
easy to support.
Additionally, files created by KiCad version 5.1 remain 100%
compatible with files created by version 5.0.
Of course no new stable version of KiCad would be complete without
many, many bug fixes so please consider upgrading as soon as
possible. This version will be the only supported version of KiCad
moving forward. There will be no further releases of the 5.0 series.
Version 5.1.0 is built from the source code in the lp:kicad/5.1
branch.
KiCad binaries will be available for download for Windows, MacOS, and
Linux are available or will be in the very near future. See the KiCad
download page for guidance.
Thank you to all developers, packagers, librarians, document writers,
translators, and everyone else who helped make this release
possible. We hope you enjoy the latest release of KiCad.

KiCad 5 - A New Generation
2018-07-22
Almost a year after the release of KiCad 4.0.7, the KiCad development
team is proud to present a new and improved KiCad 5.0 release!
The stable release version 5.0.0 is made from the stable 5.0 branch.
KiCad binaries should be available now or in the very near future for
download for Windows, macOS and Linux. See the download page for
guidance.
http://kicad-pcb.org/post/release-5.0.0/
pkglint -Wall -r -F cad
Manually fixed the indentation in cad/ghdl/Makefile because SITES.* was
(by the current definition) not long enough to count as an outlier line,
and because of this, all other lines were aligned to that line.
3.3.100 20mar19 FSDB fix for variable declarations of array of reals.
Added Real, Time, Enum, and Popcnt flags to Edit/Show-Change.
Ensure Show-Change regenerates analog traces.
Added braces inside Tcl source command to allow spaces in
filenames for Tcl scripts.
3.3.99 09feb19 Added visible single bit glitches as a yellow dot (if enabled
with --rcvar 'vcd_preserve_glitches on').
Fixed print routine broken by bsearch_trunc() optimization in
version 3.3.96.
Verilator is the fastest free Verilog HDL simulator, and outperforms
most commercial simulators. Verilator compiles synthesizable
SystemVerilog (generally not test-bench code), plus some SystemVerilog
and Synthesis assertions into single- or multithreaded C++ or
SystemC code. Verilator is designed for large projects where fast
simulation performance is of primary concern, and is especially
well suited to generate executable models of CPUs for embedded
software design teams.
3.3.94 03sep18 Applied ghwlib.c patch for dealing with null ranges.
Added second chance algorithm for find_dumpfile() in case
it fails.
3.3.95 07oct18 Added fflush on stdout for help text as fix for possible
stdout problem with mingw/msys shells.
Added preliminary support for Time datatype.
Warnings fixes for Verilator integration.
Fixed install_proc_filter usage for Tcl invocation.
Change integer type to "integer" in SST to differentiate it
from sv ints.
Premiminary support for enum tables embedded in FST files.
3.3.96 15nov18 Changed to standardized zoom in/out/full hotkeys.
Added time backtracking warning (for partial mode) to lxt2vcd.
VCD time backtracking fix (not for interactive mode).
Added drag_failed handling (can press ESC) to DnD operations.
Prevent missing file in savefile from causing savefile to be
read as VCD by mistake.
Changed to Dinotrace-like 0s/1s rendering for bit vectors so
values can be discerned without seeing the full value text.
Removed unneeded pango_layout_get_extents() inside call for
font_engine_draw_string().
Changed bsearch_trunc() to run in constant time when monospace
fonts are in use.
Added missing GDK_SCROLL_MASK to signal area (need for gtk3,
but not for other versions for some reason).
3.3.97 23nov18 Need to set menu_wlist entry NULL on gtk_widget_destroy().
Fix on vtype()/vtype2() to detect 'x' and make the coloration
red on newly-displayed traces. (Bug new from Dinotrace-like
rendering in 3.3.96.)
3.0.11:
- [FIX] Repair Environment.exit() to support PEP-479 and Python 3.7.
- [FIX] Fix wrong usage_since calculation in preemptions
- [NEW] Add "Time and Scheduling" section to docs
- [CHANGE] Move Interrupt from events to exceptions
- [FIX] Various minor documentation improvements

* Use Qt 5 instead of Qt 4
Changelog:
0.25.3 (2018-05-03):
* Enhancement: Compile option to use libcurl instead of QtNetwork
This workaround enables builds on the native CentOS6
configuration with the package manager functional.
* Enhancement: Pass label (text) layers through DRC script
The "labels" method now allows copying labels from a layer
to the output.
* Enhancement: New "split" method for polygons
This method will fragment the polygons into two or more
smaller parts for reducing their vertex count.
* Enhancement: New "dtrans" method for RecursiveShapeIterator
This method delivers the transformation in micron unit space
* Enhancement: New "insert" methods for Shapes
Shapes can now insert from another Shapes container and
from a RecursiveShapeIterator. Possible applications are
fast flattening and fast region selection.
* Enhancement: New method to generate RDB items from shapes
RdbItem#add_value from a shape, RdbDatabase#create_items
from a shapes container or recursive shape iterator and
RdbDatabase#create_item from a shape.
* Enhancement: DXF and CIF "keep layer names"
If this option is set in the reader options, layer names
are not translated into GDS layer/datatype pairs.
Specifically a layer called "L5" for example is not
translated to 5/0 and to "L5D0" on output correspondingly.
The buddy script option is "--keep-layer-names".
* Enhancement: DXF contour joining accuracy
On the DXF reader's options, a contour joining accuracy
can be specified. Small gaps smaller than this accuracy
will be closed when forming joined contours from edges.
The buddy script option is --dxf-contour-accuracy=value.
* Bugfix: DXF display issue
In some cases, DXF cell instances did not trigger bounding
box update and the cells only got visible after save and
load.
* Bugfix: XOR progress is more realistic
The progress is updated after the layer has been computed,
not before.
* Bugfix: https://github.com/klayoutmatthias/klayout/issues/117
DTrans#itype was broken.
* Bugfix: https://github.com/klayoutmatthias/klayout/issues/116
Fixed a polygon decomposition bug when writing GDS files
with big polygons with many holes. As a side effect, the
polygons with many holes computed by a NOT operation for
example are less complex and spikes in the cutlines are
avoided.
* Bugfix: https://github.com/klayoutmatthias/klayout/issues/115
Reader options were not persisted.
* Bugfix: https://github.com/klayoutmatthias/klayout/issues/114
Custom line styles not loaded from tech's layer properties
file.
* Enhancement: https://github.com/klayoutmatthias/klayout/issues/113
The XOR tool has an option now to heal result shapes which
cross tile boundaries. The result shape count of tiled
and non-tiled mode should basically be the same then.
* Bugfix: https://github.com/klayoutmatthias/klayout/issues/112
Salt package repository relative paths have not been working.
* Bugfix: https://github.com/klayoutmatthias/klayout/issues/109

they are thrown. To exclude a file press the new "Ignore" button
when the debugger tells you an exception has been generated.
To re-able exception reporting, clear the list of the files
in the IDE settings ("Debugging" tab)
The macro IDE settings can now be edited in the File/Setup
dialog.

recursion required for transaction traces).
### Version 1.3.1 (Jun 29, 2018)
* `PolygonSet` becomes the base class for all polygons, in particular `Polygon` and `Rectangle`.
* Added `Cell.remove_polygons` and `Cell.remove_labels` functions to allow filtering a cell contents based, for example, on each element's layer.
* Added `PolygonSet.scale` utility method.
* Added `PolygonSet.get_bounding_box` utility method.
* Added argument `timestamp` to `Cell.to_gds`, `GdsLibrary.write_gds` and `GdsWriter`.
* Added `unit` and `precision` arguments to `GdsLibrary` initialization and removed from its `write_gds` method.
* Changed the meaning of argument `unit` in `GdsLibrary.read_gds`.
* Improved `slice` to avoid errors when slicing in multiple positions at once.
* Improved `PolygonSet.fracture` to reduce number of function calls.
* Removed incorrect absolute flags for magnification and rotation in `CellReference` and `CellArray`.
* Minor bug fixes.
* Documentation fixes.
* Removed deprecated classes and functions.
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

What’s new in MyHDL 0.10
The block decorator
Rationale
The historical approach for hierarchy extraction in MyHDL suffers from
significant issues. This results in complex code, a number of non-intuitive API
concepts, and difficulties for future development.
In this release, a new block decorator is introduced to address these issues.
For an in-depth discussion, see mep-114.
API
block() :noindex:
The block decorator enables a method-based API which is more consistent,
simplifies implementation, and reduces the size of the myhdl namespace.
The methods work on block instances, created by calling a function
decorated with the block decorator:
@block
def myblock(<ports>):
...
return <instances>
inst = myblock(<port-associations>)
# inst supports the methods of the block instance API
The API on a block instance looks as follows:
<block_instance>.run_sim(duration=None)
Run a simulation “forever” (default) or for a specified duration.
<block_instance>.config_sim(backend='myhdl', trace=False)
- Optional simulation configuration:
- backend: Defaults to ‘myhdl
- trace: Enable waveform tracing, default False.
<block_instance>.quit_sim()
Quit an active simulation. This is method is currently required because
only a single simulation can be active.
<block_instance>.convert(hdl='Verilog', **kwargs)
- Converts MyHDL code to a target HDL.
- hdl: ‘VHDL’ or ‘Verilog’. Defaults to Verilog.
- Supported keyword arguments:
- path: Destination folder. Defaults to current working dir.
- name: Module and output file name. Defaults to self.mod.__name__.
- trace: Whether the testbench should dump all signal waveforms. Defaults to
False.
- testbench: Verilog only. Specifies whether a testbench should be created.
Defaults to True.
- timescale: timescale parameter. Defaults to ‘1ns/10ps’. Verilog only.
<block_instance>.verify_convert()
Verify conversion output, by comparing target HDL simulation log with MyHDL
simulation log.
<block_instance>.analyze_convert()
Analyze conversion output by compilation with target HDL compiler.
Backwards compatibility issues
In the 0.10 release, the old API still available next to the new API based on
the block decorator.
It is likely that the old API will be deprecated in a future release, resulting
in backwards incompatibility for legacy code. Therefore, users are encouraged
to start using the new API in their development methodology.
gdsCAD is a simple, but powerful, Python package for creating, reading, and
manipulating GDSII layout files. It's suitable for scripting and interactive
use. It excels particularly in generating designs with multiple incrementally
adjusted objects. gdsCAD uses matplotlib to visualize everything from individual
geometry primitives to the entire layout.

Release Notes for gerbv-2.6.2
========================================================================
This is a minor patch release on top of gerbv-2.6.1. The change
is to property create the tarball with the build framework so that
the automake/autoconf/etc generated files are included.
========================================================================
Release Notes for gerbv-2.6.0
========================================================================
The following is a summary of the changes which went into gerbv-2.6.0.
For a complete list of changes, refer to ChangeLog. This release
is primarily a bug fix release.
Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
At the same time, fix a symbol conflict by using zlib from pkgsrc
rather than a private copy

Release notes for pcb-4.0.1
========================================================================
Dear Users,
This release fixes a number of bugs.
Kind regards,
The pcb development team
Contributors
------------
The following authors contributed to the 4.0.1 release:
- Milan Prochac
- Charles Parker
- Dan McMahill
- Sergey Alyoshin
- Igor2
- Peter Clifton
- bert
Please note that names are in no particular order and all e-mail
addresses have been removed for privacy.
User experience improvements
----------------------------
- reorchestrated the closing of the command window to not crash.
- only invalidate the screen after changes to the crosshair or mark are
complete.
Plugins
-------
- none
Exporters
---------
- fix for gcode dimensions.
- added a regression test for the IPC-D-356 exporter.
- added more documentation for the IPC-D-356 netlist exporter.
Footprints library
------------------
- add macro with more programmability for 2 pin axial components. Use
this to add a few IPC-7251 compliant footprints for axial inductors,
horizontally mounted. Use this in turn for the TDK B82145A RF chokes
family.
- add toko category and the 7P variable inductors.
- gen_geda_*.awk were nearly identical to gen_*.awk so add 2 lines to
geda.inc so we can use the same script for everything. Verified that
pcblib-newlib builds with identical results before/after.
- for the horizontally mounted axial macro add the missing bits for
marking polarity on parts like diodes.
- add PKG_RADIAL_MM100 macro for doing more general metric 2 pin radial
packages.
- add some IPC radial capacitor footprints and use those to create some
united chemicon footprints.
- add DO-41 diode package, horizontally mounted.
- add PKG_MTHOLE_GENERIC macro for fairly generic mounting holes. Use
this to define IPC mounting holes for #4 and #6 machine screws with
pan heads or flat washers for both "tight" (board < 4") and "loose"
(board > 4") fits.
- add TO-263 footprint.
- add some notes about m4 library development.
- fix problem in some possible invocations of the generic mounting hole
macro. All footprints pass syntax checks again.
- remove an extra empty attribute which is not needed and causes
warnings in the mounting hole macro.
- fix clearance on the Toko 7P footprint.
- in the mounting hole macro, change the calculation of the pad size for
the support vias to make them as large as possible without actually
changing the copper (the support vias are covered by the main pad).
This does not affect the fabricated board but it does remove some
false positive DRC complaints.
Developer experience improvements
---------------------------------
- allow translators to change number of tabs in message.
- In the test suite, check for a working X display using xhost before
running action script tests
- match() with 3 arguments is a gawk extension. Rework the code to avoid
using a 3 argument call to match() in one spot. Lets the script run
with gawk or NetBSD's awk (20121220). Verified that the generated
result is identical to the previous gawk result using both gawk and
NetBSDs awk.
- change from AC_FD_CC to AS_MESSAGE_LOG_FD
- removed the antifork abomination.
- disabled one of the checks used to deal with older gdlib installs on
some linux systems when building under cygwin as the test has
problems. Repairs building for mingw under cygwin.
- when building under cygwin, create a pcbtest.bat batch file that
allows testing the compiled pcb without installing. This is somewhat
analogous to the pcbtest.sh script generated on linux and other
unix-like systems.
- cleanup the win32 build script a good bit. An important change is
that instead of blindly installing all of the mingw cross system root
files, only install a set of listed ones. This not only reduces the
size of the windows installer but makes sure we have a more repeatable
build and know what we are actually bundling into the installer.
- fixed the Attribute deletion code.
Notes for early adapters
------------------------
- none
Changed dependencies
--------------------
- none
Fixed and committed Launchpad bug reports
-----------------------------------------
#700193 Append branch to version string.
#917308 m4lib_to_newlib.sh does not work with mawk.

#1672886 Crash when reopening command entry window in gtk.
#1674133 Last action executed when escaping from command entry.
#1682654 Drawing area redrawn twice when crosshair moves.
========================================================================
3.3.86 03oct17 Added recurse import function (found before only in the hier
search) into the SST.
Removed obsolete bundle functionality from SST as recurse
import more accurately imports recursively.
Made entrybox taller (using -1) as recent versions of
gnome have taller window titlebars and the widget was not
tall enough.
3.3.84 03sep17 Updated FSDB reader with experimental FST tree build
routines for faster init.
Removed warnings found when compiling with -Wshadow.
Automatically enable --comphier for FST/FSDB/AE2 if facility
count reaches 500000. This is to reduce memory consumption
for traces with very many signals. Added disable_auto_comphier
to override this behavior.
Fix null pointer sent to gtk_clipboard_set_text() for
mouseover to clipboard cut ops.
- Fix issue of raise exception when sweep along with cornered line
- osx ifx: Visualization, Font_FontMgr - do not look for fonts.dir on OS X

- Fix missing include and other minor header issues
- Fix clockget_time detection on osx
-----------------------------
3.3.80 17mar17 Added "/View/Mouseover Copies To Clipboard" menu option to
allow copying values into the clipboard so they can be pasted
into text editors, etc.
----------------------------
3.16.7 (2017/03/21)
Bug fixes:
FS#1560 - Main menu not selectable (Ubuntu 16.04, Unity)
FS#1561 - Edit > Drawing Preferences: menu missing (macOS, French locale)
------------------------------
(from: http://klayout.de/development.html)
Version 0.24.10
Release date: 2017-04-01
Features:
Enhancements: New method CellView#is_dirty? This method indicates
that a cell view needs saving
Bugfix: DEF reader was not able to read routing Routed segments
with vias plus continued wiring were not read. Instead an error
message was shown saying "Invalid orientation specification"
Bugfix: Setting "technology-data" configuration property did not
work Reading or writing the "technology-data" configuration
property is the only way to access technology data from a
script. Hence it's important that this property can be set. With
this patch, "technology-data" can be set to an XML string which
has the same format than the one stored within the configuration
file.
Bugfix: Reader issues with some RVE files The RVE reader could not
read files with cell names containing hyphens (like "A-B").
Bugfix: Inplace operators are now working in Python too For
example "r1 += r2" was not working (r1 and r2 are pya.Region
objects for example).

SOLVESPACE is a parametric 3d CAD program. Applications include:
modeling 3d parts - draw with extrudes, revolves, and Boolean
(union / difference) operations
modeling 2d parts - draw the part as a single section, and export
DXF, PDF, SVG; use 3d assembly to verify fit
3d-printed parts - export the STL or other triangle mesh expected
by most 3d printers
preparing CAM data - export 2d vector art for a waterjet machine
or laser cutter; or generate STEP or STL, for import into
third-party CAM software for machining
mechanism design - use the constraint solver to simulate planar
or spatial linkages, with pin, ball, or slide joints
plane and solid geometry - replace hand-solved trigonometry and
spreadsheets with a live dimensioned drawing

Release notes for pcb-4.0.0
========================================================================
Dear Users,
It has been quite some time since the last snapshot of pcb was released
in March 2014.
Since then quite a lot of bugs were fixed and new features added, below
this introduction a summary is given of the improvements and additions
since the latest snapshot "pcb-20140316".
This release represents over 480 commits (mostly bugfixes and code
refactoring) and as such this summary clearly is not complete.
This pcb release 4.0.0 has a significant change in the major version
number.
This is done to make a fresh start and to get away from the 1.99z
version with YYYYMMDD snapshots.
Kind regards,
The pcb development team
User experience improvements
----------------------------
- added the command-line option --save-metric-only.
- added escaping of Attribute values.
- added a translation of the Getting Started with PCB for pt_BR.
- added translatable tooltips for toolbar buttons.
- added "Report net length" to Menu -> Info in Gtk.
- added a script for generating a key binding list.
- added tooltips in the GTK HID UI.
- the puller no longer crosses unplated holes.
- solder/component outer layer names changed to top/bottom.
- pcb now uses a tilde instead of a dash for backup filenames.
- corrections in the user documentation.
- the position "delta" display no longer forces the GTK HID window to
grow.
- write time in ASCII locale into exported files.
- allow for up to 10000 dpi on png exporter output.
Plugins
-------
- added smartdisperse for dispersing elements better, contributed by
Ben Jackson.
- added relocate for relocating elements, contributed by Jean Richard.
- added RenumberBlock() and RenumberBuffer(), contributed by DJ Delorie.
- added teardrops(), contributed by DJ Delorie.
Exporters
---------
- added a netlister conforming to the IPC-D-356 standard, contributed by
Jerome Marchand.
- changed "as-shown" to "screen-layer-order" in the png and eps hids.
Footprints library
------------------
- added a SC88A footprint.
- added a LQFP80-10 footprint.
- added QFN24_5 and TQFN24_5 footprints.
- added a SOD523 footprint.
- the SOT325 package had a wrong numbering.
- renamed the SOT325 footprint to SOT353.
- in the ALF footprint the drill holes were too tight.
- an infinite loop in the SIL m4 macro was fixed.
Developer experience improvements
---------------------------------
- made a start with adding Doxygen developer documentation tags in the
source files.
A pcb.dox configuration file is available in the "doc/doxygen"
directory so developers can build the documentation there by invoking
"doxygen pcb.dox" from the CLI.
This is not done by configuring with --enable-docs, which is solely
reserved for the generation of User documentation.
- added numerous fixes in the win32 target.
Notes for early adapters
------------------------
In the git repository two tags have been added to allow for checking
out of pcb-4.0.0 at the branch point (git checkout pcb-4.0.0-base) or at
the release point (git checkout pcb-4.0.0-RELEASE).
This is in line with tagging done in former snapshots.
Changed dependencies
--------------------
- autoconf 2.60 --> 2.69.
- gettext 0.14 --> 0.19.3.

Release notes for EAGLE 7.7.0
=============================
* Licensing:
- Update of various spots in EAGLE regarding the license changes introduced
by Autodesk: Standard, Premium, Ultimate, Express and Educational.
The 30 day trial license has been removed.
* ULPs:
- Added 'manufacturing.ulp' provided by Autodesk. It supports an upload of EAGLE
drawing files to 'circuits.io' in order to generate manufacturing data which
can then be downloaded. The ULP is accessible as an icon in the board editor.
- Added 'ecadio.ulp' provided by Autodesk. It supports an upload of EAGLE boards
to 'ecad.io' in order to generate a 3D PCB for use in MCAD systems.
The ULP is accessible as an icon in the board editor.
* UI improvements:
- Added Option.SignalNames to display the signal names on the signal wires
and on the connected pads and SMDs.
It can be set in the Settings dialog under 'Misc/Display signal names'.
- The options Option.SignalNames, Option.PadNames and Option.ViaLength are
set to 'On' by default.
* Miscellaneous:
- Improved visibility of scrollbars for common window styles on Linux.
- Silently ignoring double references to a contact within a signal when loading
a board file.
- CAM Processor: when running 'Process Job' with more than one section,
it is checked if the job covers the Layer Setup only partially.
- The file locking option has been switched off by default. Use 'Backup/Locking'
under 'Options' in Control Panel to turn it on.
- Update of EAGLE logo to the new appearance since Autodesk acquisition.
- Update of Hungarian translation (GUI without help and manual).
* Bugfixes:
- Fixed UL functions strsplit() and lookup() to handle unusual UTF8 characters
as separator.
- Fixed potential crash of the 64 bit versions when loading EAGLE drawings
from old format (e.g. V3.55).
- Image export to TIFF format in monochrome: fixed a regression regarding the
compression method.
- The selected object is no longer removed from the group after running a ULP
started through 'SET CONTEXT Object ...'; the ULP might want to use this
one-object group afterwards with e.g. 'exit("move (>@)")'.
- Ensuring valid move of polygon wires or an entire polygon if selecting a
wire with 'SET CONTEXT Wire ...' or using setgroup() in a ULP.
- Fixed history of dlgStringEdit to become case sensitive.
- Fix for refresh of images in Control Panel preview on Windows.
- Added a check for identical pinrefs when loading a schematic to avoid a
possible crash.

Commit Log => https://github.com/LibreCAD/LibreCAD/commits/2.1.2
This large commit accomplishes the following:
1) Switch USE_LANGUAGES=ada to require lang/gcc5-aux (gcc 5.4) instead
of lang/gcc-aux (gcc 4.9.2) on gcc.mk
2) Bump affected ports and fix paths as necessary
3) Upgrade devel/gprbuild to the latest release
- No longer requires lang/gnat_util
- gprslave requires gcc6-aux, so it was disabled for now
4) Fix lang/gnat_util but set PKG_SKIP_REASON
- It has no further purpose in the pkgsrc tree
- It has no practical purpose outside of the pkgsrc tree
- Indicate intent to remove from tree in Jan. 2017
5) Set devel/GPS as failed with PKG_FAIL_REASON
- This version of GPS is several years old and at the time they were
strongly tied to compiler.
- Latest release of GPS require gcc6-aux (not available) and several
new and complex dependencies
- maintainer (me) has no interest to continue supporting it
- Leaving GPS in place until Jan 2017 to give another person chance to
upgrade and take over support
- Latest version in FreeBSD Ports Collection as a reference point
-----------------------------
3.3.77 03oct16 Updated documentation to include an appendix on FST
implementation details.
Removed '!A || (A && B)' is equivalent to '!A || B' redundant
condition checks where found in source.
Added hier_ignore_escapes rc variable.
Dynamic resizing tweaks for when it is turned off.
Added HUWL-? value types to signal_change_list() to keep GHW
files from crashing Tcl scripts.

upstream changelog
==================
What’s new in MyHDL 0.9
Python 3 support
Experimental Python 3 support has been added to MyHDL 0.9. This was a major effort to modernize the code. As a result, Python 2 and 3 are supported from a single codebase.
See Python 3 Support for more info.
Interfaces (Conversion of attribute accesses)
Rationale
Complex designs often have many signals that are passed to different levels of hierarchy. Typically, many signals logically belong together. This can be modelled by an interface: an object that has a number of Signal objects as its attributes. Grouping signals into an interface simplifies the code, improves efficiency, and reduces errors.
The following is an example of an interface definition:
class Complex:
def __init__(self, min=-2, max=2):
self.real = Signal(intbv(0, min=min, max=max))
self.imag = Signal(intbv(0, min=min, max=max))
Although previous versions supported interfaces for modeling, they were not convertible. MyHDL 0.9 now supports conversion of designs that use interfaces.
The following is an example using the above Complex interface definition:
a,b = Complex(-8,8), Complex(-8,8)
c = Complex(-128,128)
def complex_multiply(clock, reset, a, b, c):
@always_seq(clock.posedge, reset=reset)
def cmult():
c.real.next = (a.real*b.real) - (a.imag*b.imag)
c.imag.next = (a.real*b.imag) + (a.imag*b.real)
return cmult
Solution
The proposed solution is to create unique names for attributes which are used by MyHDL generators. The converter will create a unique name by using the name of the parent and the name of the attribute along with the name of the MyHDL module instance. The converter will essentially replace the ”.” with an “_” for each interface element. In essence, interfaces are supported using hierarchical name expansion and name mangling.
Note that the MyHDL convertor supports interfaces, even though the target HDLs do not. This is another great example where the convertor supports a high-level feature that is not available in the target HDLs.
See also
For additional information see the original proposal mep-107.
Other noteworthy improvements
ConcatSignal interface
The interface of ConcatSignal was enhanced. In addition to signals, you can now also use constant values in the concatenation.
std_logic type ports
toVHDL() has a new attibute std_logic_ports. When set, only std_logic type ports are used in the interface of the top-level VHDL module.
Development flow
The MyHDL development flow has been modernized by moving to git and github for version control. In addition, travis has set up so that all pull requests are tested automatically, enabling continuous intergration.
Acknowledgments
The Python 3 support effort was coordinated by Keerthan Jaic, who also implemented most of if. Convertible interfaces were championed by Chris Felton, and implemented by Keerthan Jaic.
MyHDL development is a collaborative effort, as can be seen on github. Thanks to all who contributed with suggestions, issues and pull requests.
It's a rename of cad/verilog to a better name.
Updated DESCR for new package:
Icarus Verilog is intended to compile ALL of the Verilog HDL as described in
the IEEE-1364 standard. Of course, it's not quite there yet. It does currently
handle a mix of structural and behavioral constructs.
Icarus Verilog is not aimed at being a simulator in the traditional sense, but
a compiler that generates code employed by back-end tools.
No objections to rename from <gdt>
pkgsrc changes:
- note GitHub tags (but not use them for now)
- remove conflict with nonexistent verilog-current
- install additional documentation in share/doc/ivl (not share/ivl)
- drop DESTDIR gymnastics - build works without it
- (re)enable gperf dependency
- regenerate buildlink3.mk
- drop patches/patch-lexor_keyword.cc - no longer needed
- patches/patch-vpi_Makefile partially fixed upstream - rest not needed
upstream changelog
==================
Probably the only notes available:
Here are the release notes for Icarus Verilog release branch 10. The 10
release is a huge improvement over the 0.9 release series, in every
aspect. Much more of the Verilog and SystemVerilog language is supported,
many bugs have been fixed, and performance has improved. The changes
(improvements!) are so numerous that there is no point attempting to
enumerate them.
-- http://iverilog.wikia.com/wiki/Release_Notes_Icarus_Verilog_10
Local changes:
- set LICENSE (gnu-gpl-v2)
- replace DEPENDS of verilog to blk3
- stop replacing shebang for WISH - no longer needed
- stop helping to find tclConfig.sh and tkConfig.sh - no longer needed
- comment rationale for -DUSE_INTERP_RESULT (TCL/TK compatibility)
- drop patch-src_lxt2__read.c - fixed upstream (differently)
- comment and regenerate patch-src_lxt2__read.h
Upstream changelog (partial changes prior 0.7 not known)
==================
0.7.10
Stable release covered-0.7.10 made. This release updates the FST library to the latest version which contains some fixes and enhancements.
Stable release covered-0.7.9
11/21/2010 01:03 AM Filed in: Releases
Stable release covered-0.7.9 made. This release is a bug fix and minor feature enhancement release. Here are the details:
Cleaned up error messages emitted from the clang utility.
Updated GUI to use the ttk styled widgets for a more uniform look and allows the user to change the overall look of the GUI using a preference item.
Handling issue where a CDD file was created in a different directory and we attempt to load it in a different environment. Previously, a stack trace was emitted rather than just the user error message.
Updated copyright dates to include 2010
Added FST dumpfile scoring (new -fst option added to the score command to accommodate this option).
Adding support for "wire real" and associated code to Verilog parser.
Fixing issue with memory coverage.
Fixing bug 3054545. When a merged CDD file was used in an exclude command, a segmentation fault would occur.
Added support for constant assignment to reals.
Added support for "parameter integer" and "parameter real".
Added parsing support for the $fopenw system task.
Added support for performing +: and -: part selection on the left-hand-side of assignment expressions.
Fixed various memory overrun and memory leak issues that caused instability issues within the GUI.
Fixed GUI combinational logic issue where incorrect highlighting/underlining was occurring for uncovered expressions.
Fixed GUI issue with next/previous button traversal for combinational logic.
Enhanced the regression suite to verify all of the new features mentioned above.
Updated user guide HTML output to include the Covered banner to the top of each page.
User guide and man pages have been updated per these changes.
On a side note, active work on Covered's development branch(es) has stopped indefinitely. I plan to support the current feature set in the 0.7.x branch with possible minor enhancements as requested. Please feel free to continue to send me e-mail and/or submit bug reports against the 0.7.x stable releases.
Stable release covered-0.7.8
03/24/2010 10:20 PM Filed in: Releases
Stable release covered-0.7.8 made. This release is primarily a bug fix release, but it does contain a few new
minor features and Verilog language enhancements. Here are the details:
Fixed bug 2912587. Using the -f option with the merge command was causing errors.
Fixed bug 2912679. If the GUI was invoked (i.e., covered report -view) and an error in command-line parsing occurred, Covered segfaulted.
Added ability to specify the CDD on the report command-line when starting the GUI (i.e., covered report -view foobar.cdd) which will automatically load the specified CDD files into the GUI on startup. Feature request 2912698.
Fixed bug 2925756. An expression surrounded by the parenthesis could cause a segmentation fault when parsing.
Support has been added for NC-Verilog VPI usage.
Fixed bug 2926579. Changing from a known value to an X value should cause no change in toggle coverage; however, when we transition back to a known value and it differs from the previously known value, we record a toggle coverage change. Example: 0 -> X -> 0 (no change in coverage), 0 -> X -> 1 (change in coverage).
Fixed bug 2927285. Segmentation faults could occur when excluding FSM and combinational logic cases.
Added support for the $clog system function call.
Fixed bug 2929948. Assignments to a concatentation of signals could lead to segmentation fault.
Fixed issue in the LXT2 reader that resulted in a memory leak.
Fixed bug 2933112. Added full support for out-of-bounds assignment.
Added new -T global option that provides a "terse" output which outputs the Covered header and warnings/errors only (less output than using none of the global output verbosity options). Feature request 2952492.
Fixed bug 2960887. Adds support for creating a definition which contains no user value (i.e., `define FOO). Covered was incorrectly assigning a value of 1 to these types of defines.
Fixed bug 2958529. Zero width replications are now supported by Covered (i.e., {0{a & b}})
Fixed bug 2974860. Fixed issue with FSM state input/output variables being output to an ASCII report file correctly.
Added ability to allow the "trans" parameter to Covered FSM attributes to contain additional characters after it. Some simulators don't like Verilog attributes having the same name for multiple parameters. Feature request 2976039.
User guide has been updated per these changes.
Development release covered-20091126
11/26/2009 10:10 PM Filed in: Releases
Development release covered-20091126 made. This is a bug fix release only.

Fixed bug 2881869. Fixed a stack overflow issue in the gen_item_resolve function that would cause segmentation faults when too many items were being generated within a single generate block.
Fixed bug 2882433. Fixed the "ERROR! Parameter used in expression but not defined in current module" error when a generated module instance has a parameter override of a parameter with the same name as the parameter within the module that contains the generate block.
Stable release covered-0.7.6
08/24/2009 10:12 PM Filed in: Releases
Stable release covered-0.7.6 made. This is a bug fix release only.
Fixed misspelling in report generator code (misspelling showed up in text reports)

Fixed bug 2808818. If a generate variable name collided with a reg/wire name, Covered was not emitting an error.
Fixed bug 2808820. If no signal was used from the dumpfile and at least one signal needs information from the dumpfile, Covered needed to signal a user error.
Fixed bug 2812321. Parameterized/generated modules could get incorrect coverage calculated for them.
Fixed bug 2812495. Fixed a crash issue. There is another part to this bug report that is not fixed, however.

Development release covered-20090802
08/02/2009 10:19 PM Filed in: Releases
Development release covered-20090802 made. This development release adds several performance enhancements and bug fixes to the new inlined code coverage flow, including the following:
Adding support for $random and $urandom system calls to inlined coverage.
Includes all fixes made to the stable 0.7.5 release.
Adding support for $value$plusargs system calls to inlined coverage.
Fixing issue with generated IF statements.
Added user documentation for inlined coverage flow and score options.
Fixing issue with generated code interrupting comma-separated assign statements.
Performed code simplification and performance improvement with the way statements were handled internally.
Removed unnecessary calls to simulation functions when using inlined code coverage (this added a performance penalty).
Improved performance of inlined code generator for sizing generated signals.
Fixed memory indexing issues related to memory coverage.
Added support for static function and static ternary operators for inlined code coverage.
Added code to differentiate functions used statically and not to do the right thing for inlined code coverage accumulation.
Added vcd_diff script which checks the dumpfile output from non-inlined and inlined design files to verify that the inlined code generator does not change the result. This check is now a part of all inlined regression runs.
Made several performance improvements to the VCD file reader. The reader is now 10-20% faster.
Added support for Verilator regressions runs and ported a couple of diagnostics to Verilator format.
Adding check to make sure that a CDD file without inlined mode set that reads a VCD file containing inlined coverage data emits an error to the user and exits gracefully.
Added -inline-comb-depth score option to allow the user to specify a shallower combinational coverage depth to be generated -- improving inlined simulation and coverage performance.
For Verilator runs, inserted pragmas around intermediate combinational logic expression signals to exclude them from being output to VCD files. This improves simulation and coverage performance for Verilator runs (other simulators that have a VPI that automatically remove these signals from generating change callbacks).
Performing code replace of some actual code with pre-calculated intermediate expression values for further simulation performance improvements.
Added "e" option to -inline-metrics which allows event coverage to be turned on/off independently of other combinational logic coverage. This allows further simulation and coverage performance improvements (especially for Verilator runs).
Added optimization that causes code generation to be skipped for assertion files when assertion coverage is not required.
Full regressions now runs cleanly with all code changes.
Stable release covered-0.7.4
06/17/2009 10:21 PM Filed in: Releases
Stable release covered-0.7.4 made. This is a bug fix release only.
Updated regression files for the new 2.4 version of the OVL.
Fixed bug 2804585. Memory reads in LHS part selects were not being marked for memory coverage.
Fixed issue with VPI usage in a VCS simulation with generate statements.
Fixed bug 2805191. Automatic tasks/functions that manipulate variables outside of the task/function can cause incorrect toggle coverage for those signals.
Fixed bug 2806855. Generate blocks generating module instantiations could lead to score command errors (segfaults, internal assertion errors, etc.)
Stable release covered-0.7.3
06/04/2009 10:22 PM Filed in: Releases
Stable release covered-0.7.3 made. This primarily fixes a few bugs in the compile of Covered "out of the box". It seems that even with the regression testbench, things can still slip through the cracks :( Anyhow, please use this release instead of the 0.7.2 release.
Stable release covered-0.7.2
05/09/2009 10:23 PM Filed in: Releases
Stable release covered-0.7.2 made. This is primarily a bug fix release with a few new features added to the CLI. Here are the details of the changes.
Fixed bug 2791651. Memory deallocation errors occurred when syntax errors were being reported by the parser.
Fixed bug 2791599. Whitespace prior to a `line or #line directive were not being handled properly.
Fixed bug 2794588. If a module was specified in a -v option after its directory was specified by the -y option to the score command, the module was not found for parsing.
Fixed bug 2794684. If a normal (not generate) case statement within a generate block will output the case expression to be output to the CDD more than once, leading to internal assertion errors when the CDD file is read.
Fixed bug 2795088. When a CDD file is opened from the wizard GUI window, the open file window can be placed behind the wizard window. Instead the wizard window should disappear once a selection button has been clicked.
Fixed bug 2795086. If the user clicked on the global exclusion reason listbox when it is empty, a Tcl/Tk error message box was raised.
Fixed bug 2795089. If the GUI detailed combinational logic window is used to view several expressions one after the other, Covered can segfault.
Fixed bug 2795583. Score command segfaults when a module is instantiated within a generate block and overrides a parameter value within the module.
Fixed bug 2795640. Variables instantiated within a generate block caused issues with Covered when simulated with VCS.
Fixed bug where memory elements being assigned via non-blocking assignments were not being evaluated, leading to incorrect coverage output.
CLI updates/fixes:
When the 'debug on' command is specified, a line specifying that the debug mode is now on is output (previously nothing was output (because the debug mode was off).
Changed the 'debug on' command to 'debug less' and 'debug more' where the prior only outputs the executed statements and timestep information during simulation while the latter outputs what 'debug on' used to output (extremely verbose).
Fixed bug 2795209. When an unknown CLI command was specified, a memory error occurred.
Fixed bug 2795215. Status bar was attempting to be output during simulation when debug mode was turned on. This created some unreadable/messy output.
Changed the 'goto ' command to 'goto time '.
Added 'goto line [:]' command which simulates until the specified line number is about to be simulated.
Added 'goto expr ' command which simulates until the given expression evaluates to a value of true.
Added support for handling the Ctrl-C interrupt when the score command is simulating with the -cli option specified. In this case, simulation will immediately stop and return a CLI prompt which will allow the user to continue interacting with the simulation.
Updated user guide documentation to include the changes made to the CLI.
Stable release covered-0.7.1
05/07/2009 10:24 PM Filed in: Releases
Stable release covered-0.7.1 made. This is a bug fix release only. Here are the details:
Fixed bug 2782473. CDD files being merged from different testbenches but with similar leading hierarchy (but different top-level modules) which would lead to internal assertion errors.
Fixed bug 2785453. Wires declared in generated named scopes were not handled correctly by Covered in VPI mode of operation, leading to inaccurate coverage information.
Fixed bug 2786986. An always block with a part select in the sensitivity list was triggering on the entire signal change rather than the specific part select, leading to a potential degradation in performance and inaccuracy in coverage information.
Allow time variable types to be included for coverage.
Fixing permission issue with the install-sh script that some people would get after first downloading and installing.
Updated README and INSTALL files to be more accurate.
Fixed coverage accuracy issue for code that uses variable part selects in LHS of expressions.
