Many many improvements and bug fixes since the last packaged
release. A partial list is:
atlc should no longer fail any test on a multi-processor
system configured with --with-threads. The algorithm used
for both single processor and multiple processor (i.e.
threaded code is the same).
The -t option to atlc, which sets the number of threads
when configured for multiple processors can be set to 0
to use entirely the single-threaded algorithm. If set to
one, it will use the multi-threaded algoritm, but use
only one thread. If set to some other number, it will use
that number of threads and be optimal for the same number
of cpus.
Added some support for gathering hardware data under Linux.
Removed MPI support, as its not working at all.
Changes made to the code to remove the need for a type long long,
which should make the code more portable.
Some changes have been made to the bests so that when
the benchmark runs it should not produce junk for
the hardware information on any system. Previosly
is could create a lot of junk, that was all wrong.
uname is now only called once from try_portable.c
and the splatform specific stuff computed elsewhere
atlc now runs on anything from a toy to a supercomuter! Yes, that is
right. An early version of atlc has been run on a Sony Playstation 2
games console and version 4.4.0 has been tested on the Cray Y-MP
supercomputer!! It has also been run on a very large number of other
UNIX systems, so is hopefully very portable.
An option that was previously reccommended --enable-hardware-info
has been removed. It is now enabled by default, but can be
over-ridden with --disable-hardware-info.
Added a system call to get the number of configured
processors online in Linux. This seems to be undocumented
so it not without its risks, but it seems to work okay on the
limited number of systems tested on.
Someone has done a Windoze port of atlc. Appently it took just 5
minutes, from start to finish. A single bug was found that prevented
atlc compiling, but that was fixed - it needed a left brace removed.
This had never been seen on a UNIX system, since the offending code
was between a couple of #define's.
It has been bought to my attention that bitmaps created with Photoshop
prior to version 7.01 could not be read by atlc. This was not a
fault of Photoshop, but of atlc, so that bug has been fixed.
NEWS for realease 4.6.0 Nobember 2003.
This is a very different from the last release (4.5.1) in
two very important ways.
1) The basic accuracy for single dielectrics has been improved.
Now typical errors are only around 0.1%
2) I have re-enabled the calculation of multiple dielectrics
which were disabled due to accuracy concerns. I'm still not
100% happy with the algorithms, but on tests with a dual
coaxial cable with two dielectrics shows errors of under 2%,
I hope to improve this further at a later date.
This release contains lots of bug fixes and also contains the
initial version of the Covered report viewing GUI (line coverage only). The following is a
description of the changes made since the last development release.
- Ran C linting tool on all Covered source code and updated code based on linting errors/
warnings.
- Modified debug output to show file and line number of code that called the outputting
function (easier to debug problems and useful in error regression testing).
- Started initial error testing in regressions.
- Several bug fixes made to remove segmentation faults and assertion errors in the new
report generation functions.
- Initial version of Covered report viewing GUI added. This version displays line coverage
only at the moment.
- Fixed bug in score command for statement removal (was resulting in memory errors that led
to segmentation faults).
- Fixed bug in report command that output bad verbose information when -c option was used.
- Added new diagnostics to regression testsuite to reproduce situations where original
segmentation faults were found to occur.
- Development documentation updates. No user documentation updates are released at this
time (other than information provided using the -h global option to Covered).
Changes since the last stable release:
- User-specified FSM code coverage. By using command-line options or inline code specified
by the user, FSM code coverage can be extracted from the design. This does not include
the ability to automatically extract FSMs from the design (an ability that will be added
in future stable releases).
- Enhanced performance of the score command. A 3x - 5x speedup in the running time of the
score command on the design should be expected with this release over past stable releases.
- Enhanced readability of coverage reports. The coverage report look has been overhauled to
produce a much more readable/understandable coverage report.
- Several bug-fixes have been made, including coverage number calculation bugs.
- Development and user documentation updates.
- Enhanced regression suite.
Release Notes for Icarus Verilog Snapshot 20041004
Some minor Makefile bugs have been fixed, and source file text
formatting has in some cases been normalized for release. Also,
configure scripts have been factored for a more consistent build.
Fixed continuous assignments to carry strength when needed for correct
behavior. This bug led to subtly incorrect reset behavior, but could
have caused strength modeling errors in a variety of situations.
Fixed some <= vs >= behaviors to be consistent. The results of these
comparisons, when sized values are involved, are more standard now.
Replaced the "hspice" directory with Conrad Ziesler's
"spiceparser". The use of routine AddNTermModule() has
broken the spice input for now, although once fixed, the
results should be much improved.
Also, changed the handling of expression parameters so
that expression parameter results may be numeric, and
evaluated results are saved in the PostScript output as
instance values. When traversing the hierarchy during
redisplay, commands invoking a "selected" element will
pick up the object instance being rendered. The
combination of these changes allows the implementation
of several useful features such as counter-rotation and
displaying the name of an object within the object.
Unfortunately, guile{,14}/buildlink3.mk directly includes it, and I don't
know which dependencies actually need libltdl, so it was a recursive bump.
Hopefully this recursive inclusion can be ripped out of
guile{,14}/buildlink3.mk at some point and bubble down to dependencies that
actually use libltdl, avoiding this headache in the future....
The current release is a considerable improvement over the previous stable
release. It includes 20 months of fixes and language coverage improvements.
For a complete history of changes, see the release notes for individual
snapshots between the 0.7 and 0.8 releases found at
ftp://ftp.icarus.com/pub/eda/verilog/snapshots/pre-0.8
A brief list of highlights:
- Support for advanced standard data types such as real,
- Lots more language support in general,
- Kernel of an extensible, interactive debugger is new,
- More complete support for user supplied system functions and tasks,
including PLI system functions with various return value types,
- Better standards compliance for core system tasks and functions in
general, including some Verilog 2001 file I/O support, and
- Performance improvements in general.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
gsmc is a GTK application that allow to do all the calculation
usually done on a Smith Chart. It permits to make calculation
for network composed by resistor, capacitor, inductance, and
transmission line (also as stub). Network topology is
limited to series, parallel and as trasmissive
for trasmission line. No series connection are allowed in parallel
branch, neither parallel connection in series branch.
Trasmission line can be placed as quadrupole or as a parallel or
series stub, either opened or shorted at the other end.
Calculation procedure starts with setting the initial impedance to be
matched, next network elements are added and tuned to obtain the
desidered impedance value.
The network so obtained can be saved in spice format for other analysis;
current work can be saved for succesive retrieve.
The initial (start) impedance is thought as "the load" so when
adding a trasmission line placed as a quadrupole rotation is
clockwise, going "toward generator"; generator is placed after the
last network element, as can be seen from spice output.
TNT-MMTL, the Multilayer Multiconductor Transmission Line 2-D and 2.5-D
electromagnetic modeling tool suite, generates transmission parameters
and SPICE models from descriptions of electronics interconnect
dimensions and materials properties.
MMTL programs and supporting libraries and documentation have been
under development at the Mayo Clinic since the mid-1980s. The programs
were developed under government sponsored electronics research
programs in the Special Purpose Processor Development Group
(SPPDG). They have been employed extensively at Mayo and distributed
to some government agencies and research collaborators. At the
beginning of 2004, we decided to release the TNT graphical front-end
and MMTL programs as free software under the GNU General Public
License (GPL). Technically, MMTL programs are in the class of 2-D and
2.5-D "field solvers", which convert dimensions and materials
properties into electronic design parameters. The MMTL suite consists
of several programs, including lossy, loss-free, quasi-static, and
full-wave simulators. Circuit parameters are computed by either the
method of moments (MOM) or finite element methods (FEM). Basic
per-unit-length parameters are generated by the simulator, and can be
converted into HSPICE W-element models. MMTL is similar in many ways
to commercial field solver products which typically cost thousands of
dollars.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
The big news is that module instance arrays now work. Gate and UDP
instance arrays have worked for a while, but module instance arrays
were more tricky because of the scope arrys they create. The issues
have been dealt with, and module instance arrays are now supported.
An interesting but subtle set of bugs in the evaluation of ternary
expressions has been fixed. The problems expressed themselves when the
condition expression was constant.
Degenerate wait statements now work properly.
The @* syntax apparently missed sensitivities in l-value expressions
of assignment statements. This led to subtle bugs in carefully crafted
bits of code.
Verilog attributes are properly parsed in a few more contexts. Also,
some specify syntax cases have been fixed.
Some minor spelling and documentation errors have been fixed, along
with assorted compiler warnings.
- distfile has moved
- license has changed. Patches are the result of de-fuzzing the
old patches since the new source files have the new (less restrictive)
license.
========================================================================
Release Notes for PCB snapshot 20040903
========================================================================
- enable -Wall when compiling with gcc. Many compiler warnings have
been fixed.
- add a short man page which refers the user to the real documentation
- Added ExecuteFile(file) action which allows the execution of several
actions contained in a text file.
- Added -script <file> flag which specifies a file containing actions
to be executed upon startup.
- Various documentation improvements
- Protect some gcc extensions with tests for gcc. This allows
compilation with the IRIX c compiler.
- Add support for a background image in the drawing area which can
help in importing a layout from a scanned image.
- Updated the ~geda library 150 and 300 mil width SOIC packages
to remove silk on pads and to more closely follow the IPC
recommendations
- Added support for menu accelerators.
- segfault when breaking apart an element with no element selected
bug fixed.
- autorouter improvements
- added more 400mil DIP packages to ~geda library
- fix a trace optimizer bug which produced a segfault
- other various bug fixes
changes include:
Added support for the `default_nettype directine, including the
default net type of "none", which turns off implicit net declarations.
Signed /, % and >>> in nets should now work properly. Also, various
operators of all sorts applied to constants have been improved.
Ranges now work on localparams.
Added the system tasks $unsigned, $is_signed, $mti_random and
$mti-dist_uniform. See the make README.txt for a description of these
system functions. Also, flesh out the standard random number
generators to match the sequences generated by other compilers.
There is now an "sft" file that describes to the compiler the return
value of system functions. This allows user supplied system functions
to have interesting return types. See "SYSTEM FUNCTIO TABLE FILES" in
the iverilog man page. Include a sft file for the system functions,
and move the system functions over to that mechinism.
Fix the behavior of $fgets in tight fitting result buffers.
A variety of compilation environment fixes have been added. These
involve configure scripts and Makefiles.
And of course a variety of other bug fixes, and so on and so forth.
which are the full option names used to set rpath directives for the
linker and the compiler, respectively. In places were we are invoking
the linker, use "${LINKER_RPATH_FLAG} <path>", where the space is
inserted in case the flag is a word, e.g. -rpath. The default values
of *_RPATH_FLAG are set by the compiler/*.mk files, depending on the
compiler that you use. They may be overridden on a ${OPSYS}-specific
basis by setting _OPSYS_LINKER_RPATH_FLAG and _OPSYS_COMPILER_RPATH_FLAG,
respectively. Garbage-collect _OPSYS_RPATH_NAME and _COMPILER_LD_FLAG.
gnetman is a program which currently supports advanced SPICE
netlisting from gschem (part of the gEDA tool suite). The
primary use so far has been for complex IC design. Supported
features include multi-level hierarchy, instance arrays, and
buses. If you're just doing flat designs for PC boards or
smaller SPICE simulations, the usual path is to use the spice-sdb
netlister for gnetlist instead.
The long term goal of gnetman is far greater. Two projects under
consideration include a schematic generator, and a technology
mapping back-end for Icarus Verilog. Basically, gnetman is a
netlist manipulation database well suited for low-level
manipulation of netlists.
library dependencies (caused by the tcl/tk update to 8.4). Use tclConfig.sh
to determine which libraries are really needed. Noted in last kristerw@'s
bulk build.
* Release Notes for Icarus Verilog Snapshot 20040606
Ports of primitives can bind by name as well as by position. Also
support Verilog 2001 style port declarations for primitives.
System function return types can now be specified by system function
table files. System Function Table Files are described in the iverilog
man page. Also include better system function return types in VPI.
Non-blocking assign of real values to real variables now works.
Properly handle nul strings ("") as 8bit values. This is a weirdness
legacy of XL.
Fix some synthesis problems for logical OR and logical AND. Bitwise OR
and AND were fine. These fixes affected simulation as well.
Handle wait statements with all sorts of constant values. These are
sometimes weird, bug legal.
Handle Negative value reals, and a few other bugs related to real
numbers.
Change internal use of identifiers to perm_strings for better
performance.
Functions returning unsupported types now generate error
messages. Previously, they would quietly generate bad
code. Infrastructure is also added to eventually support arbitrary
function return types.
Better compile-time support for Cygwin vs mingw32.
The ipal target is removed from this source. (ipal is now an add-on
package that is compiled seperately.)

additions/changes since gerbv-0.15:
* projects: you can save and load setups in what I call projects.
* GTK+ 2 support
* Now you can invert a layer by the push of button. Basically.
* When gerber files were defined with omit trailing zeros, gerbv could
parse them very bad. Now it should work better.
* Aperture macros did not handle exposures at all. Now they do a better
work. Some thermals are defined from their CAD program as a sequence of
aperture macros instead of just using aperture macro 7. They are drawn
better now.
* Handles tool tables when drawing drill files thanks to Dimitri. See man
page for more info.
by moving the inclusion of buildlink3.mk files outside of the protected
region. This bug would be seen by users that have set PREFER_PKGSRC
or PREFER_NATIVE to non-default values.
BUILDLINK_PACKAGES should be ordered so that for any package in the
list, that package doesn't depend on any packages to the left of it
in the list. This ordering property is used to check for builtin
packages in the correct order. The problem was that including a
buildlink3.mk file for <pkg> correctly ensured that <pkg> was removed
from BUILDLINK_PACKAGES and appended to the end. However, since the
inclusion of any other buildlink3.mk files within that buildlink3.mk
was in a region that was protected against multiple inclusion, those
dependencies weren't also moved to the end of BUILDLINK_PACKAGES.

Covered-Related NEWS
====================
* 04/11/2004
Release covered-20040210 made. A lot of work has gone into this release to make the report
output more readable and concise. Several bug fixes have been made as well. A GUI is on
the way for report viewing that will be available in alpha version in the next development
release. Below are some of the highlights of this release.
- Added GUI interfacing functions in preparation of upcoming GUI report viewing utility.
- Added more information about expressions to line and combinational logic coverage verbose
information. Rather than just outputting the RHS of the expression, the LHS and assignment
operator (blocking or non-blocking) or IF statement are output to give the user a better
context of the missed logic.
- Fixed bug in param.c where parameters found in the RHS of expressions that were part of
statements being removed were not being properly removed.
- Fixed bug in sim.c where expressions in tree above conditional operator were not being
evaluated if conditional expression was not at the top of tree.
- Changed output of logic in combinational logic verbose coverage reporting to (by default)
use the same format (in terms of endline characters) as the logic was found in the source
code.
- Added '-w [<line_width>]' option to report command that causes combinational logic to be
output to report as much logic as will fit in the value of <line_width> in the report. A
default value of line width is specified internally in Covered to be 105 characters;
however, the user may make this value larger or smaller to suit. This value reverses the
effect of the above bulletin. Added this option to Covered's regression suite to test.
- Completely modified output format of missing combinational logic coverage. Removed a lot
of coverage information that was extraneous. When three or more subexpressions are ANDed,
ORed, logical ANDed, or logical ORed, coverage information is output in a special way to
increase readability/understandability for this coverage.
- Added "GENERAL INFORMATION" section to all reports which specifies general information
about this report (this eliminates a lot of redundant information in the report to improve
readability).
- Added the name of the CDD file from which a report has been generated from in the
GENERAL INFORMATION section of the report.
- When a CDD file is created due to merging CDD files, the names of the original CDD files
are now stored in the merged CDD file. This information is output in the GENERAL
INFORMATION section of the report (created from this merged CDD file) to indicate to the
user this information.
- If a CDD file is created due to merging CDD files and the leading hierarchies in each of
those CDD files are different, a bullet in the GENERAL INFORMATION specifies this and
reminds the user that the leading hierarchy information will not be output in the rest of
the report (instead the string "<NA>" replaces the leading hierarchy information). This
will help to eliminate confusion when viewing the reports and fixes an outstanding bug
in Covered.
- Added starting and ending line information to module structure for GUI purposes.
- Removed scope information in CDD file for expressions, signals and statements. This
information was not used, caused CDD files to become excessive in size and mildly speeds
up reading in CDD files.
- Fixed bugs in combinational logic report section where summary coverage numbers and verbose
coverage numbers did not agree.
- Removed 'c' directory in 'diags' directory and cleaned up Makefile to run regressions.
- Masked off the value of the SET bit in expressions output to CDD files. This information
is not needed and sometimes caused regression failures due to CDD file mismatches on
different platforms or using different simulators.
- Modified regression Makefile to specify the 'vvp' command prior to the compiled VVP
executable when running Icarus Verilog regressions (due to recent change to IV).
- Changed instance-based reports to not merge child instance coverage information into parent
instance coverage information. This is not done in module-based reports, makes reading
this information confusing and doesn't provide us any extra information.
- Fixed bug where modules were being reported in verbose reports when coverage numbers were
100% covered.
- Changed toggle coverage report output to output toggle information in hexidecimal format
versus binary format. This keeps the toggle coverage information more succinct/readable.
Added underlines between every 4th hexidecimal value to help user's to discern the bit
position of a toggle bit.
- Changed the format of the report entirely to enhance readability (many changes here that
the user will immediately see).
- Updated user documentation for new changes and added new section called "Reading the
Report" which will walk the user through several reports and how to interpret the report
information. This section is still in progress at this time.
- Updates to development documentation.
- Lots of new diagnostics added to regression suite. We now have over 200 diagnostics in this
regression.
Special note: Please note that the CDD file format for this release has changed from previous
CDD files and is therefore incompatible with older versions. If you try to read a CDD file
generated from an older version of Covered with the newer version, Covered will tell you that
this cannot be done due to incompatible CDD versions.
* 11/16/2003
Release covered-20031116 made. This development release contains a new way to specify FSMs
within the design by using inline Verilog-2001 attribute syntax. There are also a lot of
bug fixes contained in this release as well as the usual user and development documentation
enhancements. See the list below for more details on the changes made for this release.
- Added better VCD parsing capability to allow bit selects to be "attached" to the signal
names in the VCD variable definition section. The newer versions of Icarus Verilog now
output this format style.
- Added ability to specify FSM location and transition information using Verilog-2001
attributes. Added many diagnostics to regress suite to verify this capability.
- Fixed bug found in stable release that caused an incorrect calculation of unary operations
performed on single-bit values. Fixes bug 835366.
- Fixed bug found in using constant values in the right-hand side of repetitive concatenation
operators. Fixes bug 832730.
- Fixed bugs in reporting of FSM coverage information in the report command.
- Fixed bug in FSM variable binding stage that caused incorrect coverage numbers to be reported
for FSM coverage.
- Fixed bug in handling variables that are too long (more than the allowed 1024 bits). Removes
memory corruption problems when this occurs. Displays warning to user that it has found
a variable that it cannot handle and gracefully disregards any logic that uses these variables.
- Updated user documentation to include new chapter on inline attributes that Covered can
now handle.
- Updated development documentation for new functions added in this release.
* 10/19/2003
Release covered-20031019 made. Lots of modifications to existing structures and supporting
code to increase scoring speed. In my testbenches, I am seeing about a 3-4x improvement
in speed. Additionally, code enhancement for allowing bit selects and signal concatenations
in command-line FSM variable descriptions are now allowed. User documentation has been
updated for these changes. Some bug fixes are also included in this release. The
following list shows the changes from last development release.
- Added ability to parse more complex state "variables". This includes the ability
to specify single and multi-bit signals and the ability to concatenate more than
one signal (or signal bit select) to make a state variable. Please see user
documentation for more information on this.
- Minor tweaks to report format for displaying filenames (only basename of filename
is output instead of the entire path).
- Fixing bug in VCD parser to allow bit select parsing of a variable when the
variable name and bit-select information are not separated by spaces (this is something
that newer versions of Icarus Verilog now does in its VCD files).
- Changed structure for vectors from ints to chars. Each vector element stores information
for one 4-state bit value and its coverage information (instead of storing 4 4-state
variables and coverage information). This reduces memory needed and increases calculation
speed on vectors.
- Fixing bug in signal_from_string function.
- Fixing bug in arc.c related to non-zero LSBs of signals.
- Added new parameter to info line in CDD file that specifies the format of the CDD file.
This is used by Covered to keep CDD files with different formats from being merged, read,
etc.
- Removed LSB information from vector and storing this information in the signal
structure. Reduces memory required, enhances speed, and fixes existing bugs with bit
selects.
- Added more diagnostics to regression suite to test new functionality.
- Updated user documentation for new changes.
* 09/25/2003
Release covered-20030925 made. This release contains the first working FSM code
coverage portion in Covered. There is a lot more to work on in the FSM code coverage
area in the way of automatic FSM extraction and state transition specification, but
this version is able to extract FSM coverage information for an FSM that is located
by the user. Please see user's manual for this release for more details on specifying
FSM location. Summary and verbose reporting are available for FSM coverage at this
point. Additionally, the data format for FSM coverage information in the CDD file
has been finalized. FSM coverage merging is also supported in this release. User and
development documentation has been updated. Please give this development version a
go to get any bugs out of the FSM code coverage engine.
In addition to the FSM coverage support, a bug was fixed in the vector_to_int()
function when converting a vector whose LSB is a non-zero value.
Here is what is on the horizon for FSM coverage that you should expect to see in the
coming development releases.
- Ability for user to specify the location of an FSM using $attribute function.
- Ability for user to specify all possible state transitions for a given FSM on the
command-line and using inline $attribute functions.
- Automatic FSM extraction including locating an FSM and extracting all possible
state transitions.
* 08/20/2003 - Stable Release 0.2.1
Some bugs were found in the covered-0.2 release that needed to be fixed to consider
Covered to be completely stable. This release (covered-0.2.1) contains these fixes
which are outlined below. Please get a hold of this stable release if you have already
downloaded covered-0.2.
- Fixing bug with the initialization of the new symtable structure. Only 255 of the
256 children of each node were being initialized correctly. Fixes a segfault problem with
the symtable_dealloc routine.
- Fixed memory leak problem with file list in parser. This was a long outstanding problem
that has now been understood and fixed.
- Added fclose() after the VCD parsing was complete.
- Fixed a memory problem with the symtable structure that caused other data structure
values to be corrupted.
- Fixed assertion error problem with VCD symbol aliasing.
* 08/16/2003
Stable release covered-0.2 finally made! This release will be the springboard
for adding FSM coverage code, code optimizations as well as a few new features
that should make the score command run much faster. Some important bug fixes
were made in this release and code optimizations have been added to the score
command. If you are getting coverage for a larger design, you should definitely
notice the speed increase. In one of my designs, the speedup was a facter of
a bit more than 3x. The following are the list of changes made for this release.
- Added -ts option to score command to allow the user to see where in the
simulation process the score command is currently at. Please see user
documentation for more details on this new option.
- Fixed bug with multiple wait event statements within same always block.
This means that the CDD files created with the last version of Covered
will be incompatible with the new CDD files.
- Fixed bug with posedge, negedge and anyedge expressions when more than
one of these is found in the same always block.
- Fixed bug in vector comparison function. Vectors will now compare to a value
of true if the values of two vectors (whose bit size is different) are equal
up to the smallest MSB of the two vectors. Before, if two vectors were not
of equal size, a compare would always evaluate to FALSE.
- Removed unnecessary global variables.
- Removed generated development documentation from release and opted to
generate these with a user 'make' in the doc directory (makes release size
smaller and is unnecessary for most users anyways).
- Development documentation updated.
- User documentation and man file updated.
* 08/06/2003
Release covered-0.2pre3 made. It has been quite a while since a release has been made
which has been due to a particularly tricky bug that was found with non-blocking
assignments. This bug generated bad coverage information (this is considered very bad!)
This release contains bug fixes and development documentation updates. If no more problems
are found with this release, I will get the 0.2 release made very soon. The following
is a list of the changes for this release.
- Fixes to line.c and toggle.c to provide better cross-platform support.
- Lots of updates to the development documentation.
- Fixed bug with properly handling hierarchical references in expressions.
- Fixing bug with single-bit parameter handling (caused a diagnostic miscompare
between Linux and Irix OS's).
- Fixed non-blocking assignment bug. This bug affected the order of execution in
Covered's simulator which resulted in bad coverage information being generated.
- Fixed bugs in divide, mod, left shift, right shift and some other expression types
to avoid converting variables that have unknown values to integers (which results
in Covered errors at run-time).
The list of changes is short, but the changes made are very necessary to getting reliable
coverage numbers from Covered. Please get a copy of this version and test it out so that
we can get the stable 0.2 release made ASAP.
* 02/18/2003
Release covered-0.2pre2 made. Bug fixes and enhancements for allowing more Verilog
code to be parsed without spewing parsing errors. The list of open bugs is empty at
the moment. I will be working on enhancing the user documents and development
documents in preparation for the stable release. The stable release will be made
next unless there are new bugs found for which the bug fixes convince me that additional
testing is necessary. The following is a list of the changes for this release.
- Fixed bug with copying instance trees for instances of modules that were previously
parsed and built into the main instance tree.
- Fixing bug in file finder so that only missing modules are displayed after the
parsing phase is completed.
- Updated output of filenames as they are parsed to give more consistent look.
- Fixing bug with leftover tmp* file when missing module error is reported.
- Adding parsing support for pullup, pulldown and gate types though these are not
supported for coverage at the current time (probably will be supported after stable
release).
- Adding parsing support for real numbers in statement delays.
- Fixing case where statement is found to be unsupported in middle of statement tree.
The entire statement tree is removed from consideration for simulation.
- Added preliminary support for parsing attributes though the parsing support is not
complete at this time.
- Fixing bug with line ordering where case statement lines were not being output
to reports.
- Fixing bug with statement deallocation for NULL statements within statement trees.
- Updates to parser for new bison version 1.875
- Added support for named blocks
- Fixing bug with handling of preprocessor directives with leading whitespace.
- Fixes/optimizations to db_add_statement function which avoids stack overflow errors.
- Added check in regard to -i option to score command. Bad -i values would cause no
coverage information to be generated but would not tell user explicitly. Error
message now provided with -i option is not specified but is needed and/or -i option
is incorrect.
- Lots of parser updates to be able to parse UDPs, escaped identifiers, specify blocks,
and some other various Verilog code that was causing parse errors or assertion errors.
- Fixed proper handling of the event type.
- Fixed bug with merging constant/parameter vector values which caused assertion error
in report command when reporting on a merged file.
- Fixed user error message for merge command when CDD files are unable to be read.
- Added new type to CDD for general CDD file information. This allows CDD files from
different testbenches with the same DUT instantiated to be properly merged.
- Fixed problem with generating report from CDD file that has not been scored. Covered
detects that the CDD file has not been scored and outputs an error message to the user
not allowing them to generate these reports.
- Added support for reading bit selects from VCD files (this information was previously
ignored). This was necessary as other simulators bit blast module ports in VCD files.
- Updated look of instance reports to display full hierarchy of an instance instead of
the instance name and the instance name of the parent module. Much easier to locate
the instance in the design now.
- Fixed bug with using -D/-Q option with merge command.
- Added merge regression testing capability to regression suite.
- Updated build environment for RedHat 8.0 requirements.
- Updates to regression suite
- Development documentation updates.
The way that Covered looks and feels for 0.2 stable release is set in stone now. Please
make sure that you test this version as much as possible to get any leftover bugs out of
the code. I only plan on updating documentation, adding code comments, and fixing bugs.
If any bugs are sent in, a 0.2pre3 release will be created, otherwise, I will make
the 0.2 stable release available.
I've got some exciting things in Covered's future in plan after 0.2 stable release,
including FSM support, new text report look, code optimizations, support to be fully
Verilog-2001 compliant, a parallel scoring algorithm, and a new GTK+ interface.
Happy testing!
* 01/05/2003
Happy New Year! Release covered-0.2pre1_20030105 made. This release is primarily a
bug fix release; however, many of the bugs required larger changes than would be
expected before a stable release. The most significant change being to the lexer which
is now split into a preprocessor and a normal lexer (before these two functions were
combined into one). As such, this is the first prelease with a second release most
likely expected before stable release. The following is a list of changes included in
this release.
- Preprocessor split out from lexer to allow proper handling of defined values within
code.
- Added -p option to score command to allow user override of preprocessor intermediate
output file.
- Fixed bug where report output was not squelched when -Q global option specified on
report command line.
- Modified regression suite to verify CDD file generation (was being performed before),
module report generation (new) and instance report generation (new) to make sure that
report output was consistent.
- Fixed bug where integer, time, real, realtime and memory data types used in expressions
where considered to be implicitly defined and given 1-bit values. When these types
are seen in expressions now, they are ignored by Covered (caused nasty segfault).
- Fixed bug when a parameterized module is instantiated more than once in a design
(sent error message to user when this occurred).
- Fixed bug where a parsed module that was required but not at the head of the module
list was not being found by the parser.
- Added internal assertions and code to verify that we never try to overrun arrays
in the VCD parsing/running stage (caused nasty segmentation fault).
- Reorganized code for symtable symbol lookup and value assignment.
- Fixing bug where a parameterized module that was instantiated in a design more than
once was not getting the correct parameter value(s).
- Fixed module search algorithm to reparse a Verilog file that contains a module
that was previously ignored (not needed at the time) but is later found to be
needed.
- Created tree.c and tree.h to handle new module search algorithm and to replace
preprocessor define tree structure.
- Updated development documentation.
- Updates to user manual and manpage for new -p option, notes from this release
and a new section that starts to describe what logic is analyzed by Covered and
which code is not analyzed.
I've got some fairly large designs being run with this version of Covered and the regression
suite has grown to over 130 diagnostics with more on the way. Keep the bug reports coming!
Release notes for the gEDA/gaf 20040111 snapshot
Changes
_________________________________________________________________________________________________________
General / Summary
* Lots of changes in most areas. This release contains the largest amount of changes in quite a while.
Expect bugs, crashes, and general instability. If you tell me about them, I might be able to fix them.
* Probably the biggest set of changes were the addition of multi-line text support. The bulk of the work was
done by Carlos. The text add dialog box and the multi attribute add/change dialog box both support the
adding and editing of multi line text items, however, I am going to change these dialog boxes in a
subsequent release to be a little like the old behavior, but still support multi-line text support. Full
multi-line text support requires that you use gtk+ 2.2.x.
* Also part of the above changes was to get rid of some fixed sized buffers within libgeda and gschem.
Hopefully I have hashed out all the bugs in these changes, but I wouldn't be surprised if I missed
something. Please report all crashes. Thanks.
* Changed the file format a little. Changed the way sch/sym files are versioned and added a field to the
text item to support the multi-line text feature addition. I recommend everybody run gsymupdate and
gschupdate (and verify the resulting files!) to get rid of the log warning message. gEDA/gaf will always
write the new file format for all saved schematic/symbols.
* The v flag (the version of the sym/sch file), in the past, was keyed off of a version date, such as
20030901. Starting with 20040111, I am no longer using this date as the version of the sch/sym file, but
rather I added a new field (number) which is the file format version. The new version line looks like:
v 20040111 1
This is nice that I don't have to update all the symbols, schematics, etc... to get rid of a log warning
message. The current version of the file format is 1. All past files are versioned as 0. As an experiment,
I left all the symbol files at v 20031231 1 and nobody should care/notice. I am planning more changes to
the file format in subsequent releases and this version field will make changing it easier.
* The text object has an additional field which is the number of lines (N) the text item contains. The text
item is then followed by N number of lines of text. Example:
T 48400 59900 9 10 1 0 0 0 3
Line1
Line2
Line3
* The component libraries:
vhdl, verilog, new asic, and the new gnetman
are commented OUT in the system-commonrc file. I did this because there are significant symbol name
clashes between these libraries. If you want to use one of these libraries, please place the appropriate
(component-library "...") string in some rc file. This commenting out is temporary, till I fix the
component name clashing bug (jitterbug#9).
* The component-library-search keyword in the system-commonrc file was commented out. If a directory is
specified for the component-library-search keyword, then libgeda/gschem/gnetlist will automatically find
any directories in the specified directory and add them to the component search path. By having this
keyword in place, this would have undone the above commenting out.
If gschem/gnetlist cannot find your custom component libraries after upgrading to 20040111, then either
comment in the component-library-search keyword back into the system-commonrc file or explicitly add the
custom component libraries to an rc file. The latter action is prefered.
This info was added on 02/08/2004.
* Upgraded all packages to use gettext (GNU gettext) 0.12.1. I don't think that anybody who downloads the
source tarballs will need this particular version, but you will certainly need it if you build the CVS
version.
* Partially applied Carlos' UTF-8 patch for gtk+ 2.2.x. I couldn't test the complete patch, so I will keep
working on this. Moving libgeda to use UTF-8 internally is going to be a bit of work, but the sooner it
happens, the better.
* The gEDA Suite setup program has been improved considerably. It now supports the download of the tarballs
automatically using wget. All you need to get from the gEDA website is the toplevel Makefile and type:
make xinstall and the setup program will do the rest. See below in the build section for more information
on using xinstall. Please report any problems with gEDA Suite setup so it can be further improved.
* Much more documentation that gets installed now (almost all of it). I included Bill Wilson's gsch2pcb
tutorial and Russ Dill's tragesym tutorial. I also am installing all READMEs, so please see the
gedadocs.html file for almost all available documentation on gEDA/gaf. You can access this file via
Help/Manual... in gschem (make sure you have a web browser installed).
libgeda
* Shared library version number now at 20.
* In 20030901, libgeda was accidentally being built without optimization. Fixed in this version.
* Applied Carlos Nieves Onega's multi-line text patch. See below in the gschem for more info. This patch
changed and fixed a lot of things in libgeda, so expect some instability.
* Applied a few more patches by Carlos to perfect the multi-line text support in libgeda (mainly dealing
with support for tabs in multi-line text items).
* Added postscript output for mutli-line text items. This support is really new and not 100% perfect. Expect
some problems here, mainly when you start rotating and changing the alignment of many line text items.
Putting tabs into the text strings is not yet supported.
* Fixed a really nasty bug in o_attrib_get_name_value() which was caused by g_strsplit() not behaving the
same between glib 1.2.x and glib 2.2.x. Be careful when using g_strsplit, especially if you use both
versions of glib. Bug caught by Stuart.
gschem
* Added the --with-stroke command line to specify where ./configure can find the libstroke files.
* Changed the behavior of the print dialog box to close when the user presses the Print button.
* Added the ability to generate PNGs from the command line. Look at gschem/scripts/image.scm for the scheme
script. Command line looks like: gschem -o test.png -s image.scm filename.sch
* Added a schem rc keyword: image-size which lets you set the size of the PNG image generated using the
above guile script.
* Applied Carlos Nieves Onega's multi-line text patch. This patch adds multi-line text support to
gschem/libgeda. This patch made some very deep changes to internals which haven't changed in years, so
expect some instability. Multi-line text is properly supported only when using gtk+ 2.2.x. You will be
able to load schematics and edit multi-line text (in a limited fashion) if you use gtk+ 1.2.x
* Part of the above patch was the removal of a bunch of fixed sized buffers. Hopefully Carlos and I have
fixed all issues surrounding these changes, but expect some instability here as well as we work out the
kinks.
* Applied a patch by Carlos to highlight the proper alignment value in the pull down menu in the Edit
Text... dialog box.
* Fixed the visual alignment of the menu items and hotkeys when using gtk+ 2.2.x.
* Improved the appearance of a few of the dialog box, by mainly adding whitespace. A few dialog box got a
few more touch ups, but nothing too drastic.
* Applied a patch by Carlos to add multi-line attribute editing to the multi attribute dialog box. The
changes for this are not complete and will change in the next release.
* Updated the pt_BR.po with Antonio's UTF-8 version.
* Applied Stuart's multi-select open patch. Now you can select multiple schematics to open using the
File/Open... dialog box. Hold down the shift or control key as you click on filenames.
* Part of Carlos' multi-line text patch was to change the quick rendering of text from a line to a
rectangle. Refined and refactored this code a little to properly display attributes.
* Fixed a long standing bug in the File/Open... and File/Close... mechanisms when dealing with multiple
windows. Bug identified by Karel Kulhav.
* Fixed a long standing bug in the preview window (for schematics and components) where there would be
garbage data in the bottom of the window. The bug only manifested itself under very specific conditions
and only when using gtk+ 1.2.x. I'm quite surprised nobody else complained about it (or rather recently).
* Applied a patch by Carlos to support the new Spanish characters.
* Fixed the invalid scrollbars on startup bug.
* Updated the man page a little bit. Added code to the build mechanism to generate an html version of the
man page, which is installed into the documentation directory.
* Bunch of other improvements and bug fixes.
gnetlist
* Upgraded Bill Wilson's gsch2pcb gnetlist backend to the latest (1.4)
* Applied all of Carlos' DRC2 patches.
* Applied all of Stuart's spice-sdb patches. The included spice-sdb backend should be Stuart's absolute
latest version. A bunch of improvements to various parts of gnetlist were included in these patches.
* Applied of Stuart's patch to the partlist backends.
* Updated the man page a little bit. Added code to the build mechanism to generate an html version of the
man page, which is installed into the documentation directory.
* Added the scheme rc keyword: unnamed-netname which lets you control what the unnamed nets should be
called.
* Add the necessary rules to the Makefiles to install all the backend READMEs into the documentation
directory.
* Applied a patch by Christopher K Eveland to fix a condition where gschem2pcb was picking up a pin when it
should not. If somebody could test gschem2pcb on an existing project and make sure it still works as
expect, it would be greatly appreciated.
* Added the Racal Redac format backend by W. Kazubski.
* Added the new RF Cascade and futurenet2 backends by Dan McMahill.
* Applied a bunch of patches by Dan for doing net aliasing/renaming. These patches touched the C files as
well as various backends.
* Applied a few more patches by Dan to fix some m4 quoting issues with the PCB backends.
* Bunch of other minor bug fixes.
gsymcheck
* No significant changes (lots of pending work though).
* Updated the man page a little bit. Added code to the build mechanism to generate an html version of the
man page, which is installed into the documentation directory.
symbols
* Werner Hoch has fixed a whole slew of symbols in various component libraries. Thanks Werner!
* Added a whole bunch of contributed symbols from various people. Thanks.
* Added a bunch of new Spanish characters by Carlos.
* Removed vhdl, verilog, asic, and gnetman from the system-commonrc file.
geda (gManager)
* Piotr Miarecki added a bunch of features and fixed a few bugs in gManager. Give it a try and let him how
gManager works for you. gManager is looking really nice.
* Integrated Antonio's pt_BR translation. This should work now.
* Added a strategic sleep to the mainloop of gManager to reduce the CPU load.
utils
* Updated Bill Wilson's gsch2pcb to version 1.4
* Add the necessary rules to the Makefiles to install all the backend READMEs into the documentation
directory.
* Integrated Stuart's garchive script.
docs
* Applied a whole bunch of patches from Dan McMahill to the symbol creation guide. These patches added/fixed
information related to the footprint= attribute.
* Started using hyperref.sty for all LaTeX generated documentation, which adds hyperlinks to the pdf files.
* Added a bunch of converted txt -> tex documents. The conversions were done by Dan McMahill.
* Added the Dan McMahill's documentation for the RF Cascade gnetlist backend.
* Rewrote the toplevel gedadocs.html index file to link all the new documentation, readmes, man pages, and
tutorials. The gedadocs.html now file contains almost all existing documentation on gEDA/gaf that I'm
aware of.
* Added a couple of tutorials that people have written. Namely Bill Wilson's gsch2pcb and Russ Dill's
tragesym tutorials. Both of these tutorials are accessible from the gedadocs.html file.
* Explicitly stated in the file formats document that all the file formats associated with gEDA/gaf are
covered by the GPL version 2.0.
* Lots of improvements and fixes to various docs.
examples
* No significant changes.
For more a detailed changes, please look in the appropriate ChangeLogs in the source tarballs.
Changes:
Library Management
* Packages and Device Sets can now be copied into the currently
edited library from other libraries, either through Drag&Drop from
the Control Panel or by using the COPY command's new extended syntax
(see "Help Copy").
* New package variants can now be created by directly using packages
from other libraries, either through Drag&Drop from the Control Panel
or by using the PACKAGE command's new extended syntax.
* The packages of the currently edited library can now be updated with
those from other libraries, either through Drag&Drop from the Control
Panel or by using the UPDATE command's new extended syntax.

- Mirroring/rotating of buffers
- Undo works on trace optimizations
- Fixed polygon undo bugs
- Fix arc DRC bugs

Gnucap 0.34 release notes (02/01/2004)
This is a bug fix and compatibility release.
1. Fix bug causing incorrect interpolation of backwards tables.
2. Fix tanh overflow bug.
3. Fix some parsing bugs.
4. Fix occasional "double load" bug.
5. Fix AC sweep with one point.
6. Transient start time really works.
7. Fix occasional assert fail after option short is changed.
8. Fix memory leak resulting from failure to delete unused common.
9. Fix a Z probe bug that sometimes gave wrong answers.
10. Fix a limiting bug that sometimes caused non-convergence.
11. Configure handles isnan.
12. Improvements to logic initialization. It is still not correct.
Some things that are still partially implemented:
1. BSIM models, charge effects, "alpha0" parameter. (computed then
ignored)
2. Configure still doesn't handle everything.
3. The model compiler still requires too much raw coding.
4. Named nodes. If you set the option "namednodes", it will support
named nodes, but some things don't work, so it is off by default.
5. The preliminary IBIS code is now included. For now, it is a
standalone executable, that reads an IBIS file and generates a
netlist. The netlist requires some editing to use, and is not fully
compatible anyway. It is included in hopes of recruiting help in
finishing the project.
Bugs (nothing new, but needs repeating):
1. The transmission line initial conditions are not propagated until
the transient analysis runs.
2. An occasional bogus calculation in MOSFETS occurs when a device is
reversed. This sometimes causes nonconvergence.
3. Initialization is strange when repeating an analysis without an
intermediate edit.
Hot items for a future release (no promises, but highly probable):
1. Verilog-AMS and VHDL-AMS support.
From the NEWS file:
This release is basically a 0.2.1 release with the available bug fixes
patches applied to it. This should make getting a stable release less
tedious.
rather than using LOWER_OPSYS. This is because the couple of os's
that had correct targets were the same and others that pkgsrc works on
aren't listed at all (like solaris). Fixes build problems noted on
solaris.
-- Release 0.15 --
2003-10-06 Stefan Petersen <spe@stacken.kth.se>
* src/draw_amacro.c: Drawing of aperture macro primitive 7 was
severly broken. Revealed by Drew Moore who sent an example
along. Thanks Drew! Closes bug #818307.
2003-09-28 Stefan Petersen <spe@stacken.kth.se>
* src/gerber.c: Patch from Peter Brueckner. Some Gerbers don't
have G04 but just G4. Peters patch fixes that for G- and M-codes.
2003-09-08 Stefan Petersen <spe@stacken.kth.se>
* src/gerber.c: Patch from Simon Munton to fix a problem with polygons
sometimes not being filled properly. Closes bug #800928 (which
he promptly had submitted).
* src/gerber.c: Another patch from Simon. This time it fixes
circular polygon outlines by with a number of short segments.
Closes bug #603183, which was almost a year old. Thanks Simon!
curses.buildlink2.mk. This was wrong because we _really_ do want to
express that we want _n_curses when we include the buildlink2.mk file.
We should have a better way to say that the NetBSD curses doesn't
quite work well enough. In fact, it's far better to depend on ncurses
by default, and exceptionally note when it's okay to use NetBSD curses
for specific packages. We will look into this again in the future.
Inspired by FreeBSD "ports".
Fix the PLISTs accordingly.
Also, while at it, remove now obsolete compileall.py calls in post-install
targets and insure that extension.mk is in included before builinlinks of
other Python modules.
Discussed with/ok'ed by drochner@.
This update is a collection of little improvements and a significant
verhaul of hardcopy plot and export.
Hardcopy and documentation output can now be obtained using either graph
or Gnuplot. A dialog box allows choosing output formas and a few other
settings. Additional plot/export filters can be plugged in by writing a
suitable scheme module.
There's a data-export function for extracting and saving a subset of a
datafile as ascii.
The stacking/drawing order of waveforms can be changed.
Selected waveforms are now drawn in a highlighted style.
USE_GCC2 or USE_GCC3 where appropriate.
the functionality of the old gcc.buildlink2.mk has been rolled into
compiler.mk now, which is automatically used.
more changes to come later...
Release notes for the gEDA/gaf 20030901 development snapshot
------------------------------------------------------------
CHANGES:
General / Summary
* The biggest change in this release is the addition of gtk+ 2.2.x
support. Now you can build gEDA/gaf with either gtk+ 1.2.x or
gtk+ 2.2.x. Some programs like setup and geda still require
gtk+ 1.2.x, but that will be fixed in a future release.
The original gtk+ 2.2.x patch was by Ye Ma (Thanks!).
* Added --with-gtk12 commandline flag to all ./configure scripts
to force the use of gtk+ 1.2.x. Just add this to the opt=
variable in the toplevel Makefile to force all of gEDA/gaf to
use gtk+ 1.2.x instead of gtk+ 2.2.x. The default used gtk+
library if both 1.2.x and 2.2.x are installed is gtk+ 2.2.x.
* In order support above, pkg-config is now REQUIRED to successfully
./configure the packages. pkg-config is also required if you
are building/linking against gtk+ 1.2.x. You can get pkg-config
from either:
[1]http://www.geda.seul.org/dist
or [2]http://www.freedesktop.org/software/pkgconfig/
* If you do not keep all of your packages installed in one
place or if it is not in a standard location (like
/usr/lib/pkgconfig), then you must tell pkg-config where
to look by using the PKG_CONFIG_PATH environment variable.
I keep all of my *.pc files in /usr/local/lib/pkgconfig,
so my PKG_CONFIG_PATH is set like this:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
* Rewrote and simplified all the ./configure.ac files. Here are
the versions of the auto* tools I use:
autoconf (GNU Autoconf) 2.54
automake (GNU automake) 1.7.1
ltmain.sh (GNU libtool) 1.4.2
aclocal (GNU automake) 1.7.1
gettext (GNU gettext) 0.11.5
If you use any other versions, good luck. :-)
libgeda
* Shared library version number now at 19.
* Removed libgeda-config, replaced with libgeda.pc (pkg-config file).
In order for gschem and the other libgeda programs to find this
file during the ./configure stage, you must set the PKG_CONFIG_PATH
environment variable to something like this:
export PKG_CONFIG_PATH=$HOME/geda/lib/pkgconfig:$PKG_CONFIG_PATH
The settings for this variable is printed when you type 'make'
in the upper most directory (toplevel) where you untarred all
the source tarballs.
* libgdgeda 2.0.15 is now required to build libgeda.
* No significant code changes.
gschem
* Applied Carlos Nieves Onega's multi attribute patch. With this
patch, the multi attribute add/edit dialog box behaves a lot
more intelligently when adding or changing attributes.
* Bunch of work to support both gtk+ 1.2.x and 2.2.x.
* Rewrote the exit dialog box to look better under both 1.2.x
and 2.2.x. Quite a few of the dialog box look bad under
1.2.x, but look absolutely dreadful under 2.2.x, so they
will be recreated (and hopefully improved in the process)
in future releases.
gnetlist
* Applied Carlos Nieves Onega's commandline (-l filename) load
scheme patch. The scheme code is loaded and executed from the
specified file before the backend is loaded.
* Added the -m commandline flag which allows scheme code to be
loaded from a file after the backend is loaded but before it is
executed.
* Integrated Carlos Nieves Onega's DRC2 backend.
* Applied Carlos Nieves Onega's warning cleanup patch.
* The required work to get gnetlist to work with both gtk+ 1.2.x and
2.2.x.
* Added Bill Wilson's gnet-gsch2pcb backend.
* Applied Stuart Brorson's latest changes to the spice-sdb
netlister. His changes included the -s command line flag
(sort output netlist) and the gnetlist:get-calling-flags as
well as improvements to the spice-sdb backend itself.
gsymcheck
* No significant changes other than the gtk+ 2.2.x support changes.
symbols
* Werner Hoch updated a bunch of symbols in various directories
including memory and 74.
* Removed gesym-config. The new ./configure.ac files do not use
this file anymore.
* Added a bunch of contributed symbols (not all though, some are
still pending for various reasons).
* The author= and email= attribute on five symbols have been
merged into one (author=).
geda (gManager)
* No changes
setup
* No changes
utils
* Finally integrated Werner Hoch's tragesym 0.0.5 into the
utils package. tragesym is a symbol creator for gEDA/gaf written
in python.
* Applied patch by Holger Dietze to update gmk_sym to be current.
* Integrated Bill Wilson's gsch2pcb package.
gsch2pcb is conceptually based on the gschem2pcb shell script
distributed with gnetlist, but additionally handles multiple
schematics, handles element file footprints, and removes pc
board elements corresponding to components deleted from the
schematics. It also forward annotates component value changes
* The necessary changes to support gtk+ 2.2.x.
* Integrated pads backannotation script by Dan McMahill.
A perl program which implements backannotation from Pads
PowerPCB board layouts to gschem schematics.
docs
* Documented the merge of author= and email= (suggestion by
Werner Hoch)

From the CHANGES file:
254 v3.1 rev 19 8/12/03
Required reconfiguring without Tcl once to generate the
"Makefile.in" in the Xw directory; otherwise, automake 1.7
becomes a requirement.
253 v3.1 rev 18 8/6/03
A fix to the output, correcting the page numbering in the
PostScript page headers. The incorrect numbering can cause
some printers to lock up. . .
252 v3.1 rev 17 7/14/03
Thanks to Ted Roth for fixing my rather too-hasty fix of
revision 16. Also: Some fixes to the autoconf script (also
from Ted Roth), and autoconf script updated to work with the
latest versions of autoconf/automake/aclocal.
for a possessive (like her, his, whose, their, and its).
Note that I didn't check for proper use of "its" (when it should
be "it is" or "it has" instead).
I also saw over 15 other grammar or punctuation problems, but not
fixed in this commit.
Covered is a Verilog code coverage analysis tool that can be useful
for determining how well a diagnostic test suite is covering the
design under test. Typically in the design verification work flow, a
design verification engineer will develop a self-checking test suite
to verify design elements/functions specified by a design's
specification document. When the test suite contains all of the tests
required by the design specification, the test writer may be asking
him/herself, "How much logic in the design is actually being
exercised?", "Does my test suite cover all of the logic under test?",
and "Am I done writing tests for the logic?". When the design
verification gets to this point, it is often useful to get some
metrics for determining logic coverage. This is where a code coverage
utility, such as Covered, is very useful.
Please note that this package is for a stable release version.
There is a seperate package (covered-current) which is made of
development snapshots.
Changes since 0.13:
* Removal of the last inclusions of malloc.h after tips
from Charles Lepple.
* Some patch that fixed a problem for Larry Doolittle
* Error messages when running RS274D instead of
"crash-and-burn" (ie segfault).
Pcb - X11 interactive printed circuit board layout system.
Pcb is a handy tool for the X Window System to design printed
circuit boards. All coordinate units are 1/1000 inch.
Please note that this package is a development snapshot and while it contains
the latest and greatest features, it may be buggy as well. There is a seperate
pcb package which is made of the stable releases.
(disable it), and another one to use memory a bit more efficiently.
The program is now usable with VCD files larger than 10M.
Update to the latest snapshot to ease discussion with the author;
a notable change in this is improved LXT support.

Release notes for the gEDA/gaf 20030525 development snapshot
------------------------------------------------------------
CHANGES:
General / Summary
* This release is mainly a packaging release. Several
contributed pieces were integrated into the gEDA/gaf
release framework including:
- Piotr Miarecki's geda (gManager)
- Piotr's gEDA Suite setup.
- geda-examples which is a tarball of various
examples of gEDA/gaf in action.
* Two new backends were also incorporated (switcap and spice-sdb)
* Improved the toplevel Makefile a little bit. Now if you are
building from a CVS checkout, you can: 1) set the PATH and
LD_LIBRARY_PATH variables (as usual) and 2) type: make install
and the Makefile will take care of running auto* as required.
libgeda
* Shared library version number still at 18 (unchanged).
* No changes for libgeda.
gschem
* Applied patch by Mario Klebsch for bug #43: "If gschemdoc is
not install, gschem crashes".
* Fixed a crash when you press the q key or any other "no-action"
key. This was changed behavior when using guile 1.6.3.
* Added "reset-component-library" and "reset-source-library" rc
keywords. Now from either ~/.gEDA/gschemrc (or gnetlistrc)
or a local gschemrc (or gnetlistrc) file, you can empty out
all the default libraries and set your own.
* Fixed the x_multimulti.nw build problem that some people ran into.
* Updated the Brazilian translation (new file supplied by Antonio).
gnetlist
* Applied a patch by Dan McMahill to get the PCBboard backend working
with guile 1.6.3
* Integrated Stuart Brorson's advanced spice backend (spice-sdb).
Please see the howto in the docs directory (docs/spice-sdb/)
for more info on this backend. The only changes I made to
Stuart's original code was to lowercase the name of the backend
(from spice-SDB to spice-sdb). Also check out his spice website
at: [1]http.
* Integrated Dan McMahill's switchcap backend. Please see the
gnetlist/docs/README.switcap for more info. Also see the
documentation in the docs package (docs/switcap) for even more
info.
* Applied a patch from Dan to the gnetlist.1 manpage.
gsymcheck
* No changes for gsymcheck.
symbols
* Werner Hoch updated a bunch of symbols in the max symbol library
along with adding a few new symbols. Thanks!
* Integrated a few new symbols for Stuart's spice backend.
* Integrated a few new symbols for Dan's switcap backend.
* Fixed 93Cx6-1.sym to include power information (patch by
Holger Dietze). (Bug#65)
* Applied Wojciech Kazubski's --with-docdir patch. Now you can
specify where the documentation is installed using --with-docdir
at the ./configure stage.
* Fixed 74/7408-2.sym and 74/7409-2.sym, these symbols were swapped.
Pointed out by Mario Klebsch.
* Integrated a bunch of symbols from various people (thanks)
who used the website upload mechanism. Btw, the website symbol
upload is so much easier for me, so please continue using it.
I think I have a few symbols I still need to finish integrating.
geda (gManager)
* From the README:
"gEDA Suite Project Manager is a start point for
everything what you may want to do. It is used to
organize your files and easy running tools. It
simplifies your job."
Even though it is called gManager or Project Manager, the
built executable is called "geda". Please play with it and
let Piotr know of any suggestions or bugs.
* This is the first release of this program inside the gEDA/gaf
framework.
* Integrated this program into the toplevel Makefile (so that it gets
built when you type make install etc...)
* If you build using the toplevel Makefile from now on, you must
have geda in the current directory.
setup
* This is Piotr's gEDA Suite Setup program.
* This is the first release of this program inside of the gEDA/gaf
framework. Please send all bug reports to Piotr.
* Here's how you use it:
1) Download all the gaf files and the required libraries
and put them all into one directory.
2) Download guile-1.4.1.tar.gz and put it also into the
above directory.
3) Type: make xinstall
4) Follow the GUI.
Setup will build and install all of gEDA/gaf. Eventually this
will be extended to build/install the rest of gEDA and gEDA
related programs. Please let Piotr know of any suggestions or
bugs.
Make sure you have guile-1.4.1.tar.gz in the current directory
along with all the gaf tarballs.
* If you build using the toplevel Makefile from now on, you must
have setup in the current directory.
utils
* Applied a patch by Charles Lepple to fix a build problem on OSX.
* Applied Wojciech Kazubski's --with-docdir patch here as well.
docs
* Integrated documentation for Dan's and Stuart's new backends.
* Applied Wojciech Kazubski's --with-docdir patch here as well.
examples
* This is the first release of the example package inside of
the gEDA/gaf framework.
* This package includes:
- Stefan's gTAG : An example of hierarchical schematics using gaf.
- Terry Porter's lightning_detector: An example of how to use
gEDA/gaf with PCB.
- Stuart Brorson's TwoStageAmp and RF_Amp : Examples of how
to use spice-sdb for single page and hierarchical SPICE
simulation using gEDA/gaf.
If anybody else has some projects they would be willing to allow
me to distribute, please let me know! I'm always looking for
examples of gEDA/gaf in real use.
* The examples are not installed, but the toplevel Makefile expects
the tarball to be untarred in the current directory.
For more a detailed ChangeLog please look in the appropriate source
directories.
There was a couple of snapshots since february; besides bugfixes the
major highligths might be:
-handling of real values at various places
-support for library modules (esp cadence PLI1)
-better FPGA support (esp Virtex II)
-"vvp" interactive mode added
Also converted to buildlink2, and dependencies to libz, libbz2 and
readline added.
The source for version 3.1 contains the first official release of the
Tcl/Tk-based version of xcircuit. At this time , everything in the
original program has been implemented in the Tk GUI. The Tcl version
has the greatest amount of command-line control, and can be run
exclusively from the command line (e.g., from a script). A
command-line argument "-exec" has been added to facilitate running
xcircuit in "batch mode".
Starting with version 3.1 revision 10, XCircuit has been made an
official part of the EDA environment including Magic, IRSIM, Netgen,
and Tclspice. Revision 10 addresses interoperability among these
applications, including use of XCircuit in conjunction with Magic for
Layout-vs.-Schematic (LVS) verification. A Magic tutorial on using
XCircuit, Magic, and Netgen together for LVS is in the works. Note
that this EDA environment requires that all applications be compiled
with Tcl/Tk.
From this point, the embedded Python interpreter interface will not be
further developed, except for essential bug fixes and such.
now and not NetBSD-*-arm32. Changes include one or more of:
- Change MACHINE_ARCH == arm32 to also match arm
- Where ONLY_FOR_PLATFORM includes NetBSD-*-arm32, add NetBSD-*-arm
- Where BROKEN or worked around for arm gcc bugs, set USE_GCC3
The last may shake out a few more broken packages the next bulk build.
