changes since the last packaged version (from the authors announcements):
Icarus Verilog snapshot 20001119
--------------------------------
The big change here (code wise) is improved and corrected constant
propagation. I was missing OR, NOR, NAND and XOR propagations, and
got some of the AND calculations wrong. This fixes this shortcoming
and in some cases this actually may speed up your compile a tiny bit.
Some more dangling signals are also eliminated.
supply nets are now working (PR#17). They also will trigger constant
propagation (as they have constant values) in certain cases.
Those of you doing cygwin compiles have trouble compiling parse.cc. I've
put into the cygwin.txt some slightly better instructions for dealing with
this situation, when it comes up.
I've also added missing symbols to ivl.def, so that tgt-stub properly
links.
Icarus Verilog snapshot 20001112
--------------------------------
This snapshot includes support for MOS et al devices as contributed
by Tim Leight. It appears to actually work as advertised, and I also
have from him a collection of tests that I'll be adding to the test
suite as soon as I get copyright information from him. So if you have
been dreaming of simulating MOS devices with Icarus Verilog, give this
a try. This update also fixed PR#27.
I've also cleared up a few bugs related to unconnected module ports.
Module port syntax is pretty byzantine, as PR#38 shows.
The loadable target API has gained access to flip-flops. This is required
for PLD code generation to work. I think the ivl_target API now supports
the minimum devices needed to generate PLD files, and I'm on to the task
of getting ancillary PAL support working.
Icarus Verilog snapshot 20001104
--------------------------------
Yes, I've managed to find the right bits to get Icarus Verilog to compile
on RedHat 7.0, and this snapshot includes those fixes. It took some back-
and-forth with tech support at RedHat to get it going.
I've also fixed up make check so that it works in general. If you use
"make check" after building, the makefile will run the examples/hello.vl
program through the local parts to make sure they minimally work.
I've added support for the "time" data time and more complete support
for the $time system function. These should work properly in all cases
now, so cases of not working are worthy of a bug report.
I've also integrated a re-implementation of sequential UDPs from Stephan
Boettcher, so I would appreciate it if all you folks using primitives
give this a fresh test. (It should be an improvement.)
This is a relatively small message, which doesn't reflect the complexity
of the changes. The "time" support in particular caused a lot of threads
to be pulled. Also, I've been doing some PLD stuff on the side, so I've
been busy.
I've also knocked of PR#11, 14, 33, 34, 39 and a few other bugs.
changes (from the announcement):
The libipal library has gained access to more structural information
about the device, including enable SOPs. It is also now possible to
lookup a SOP by name and by pin. Also, access to sop fuse positions
has been improved.
The toplevel makefiles were changed to use $(MAKE) instead of make.
There are a few other niggling makefile fixes as well.
ipalrev and ipaledit now both take the -p flag allowing you to choose
the architecture for your device, and there are now two devices to
choose from. (both 22v10s:-)
ipalrev was seriously confused about inversions and the sense of things,
but that should be all cleared up now. It does a decent, if not complete,
job of decompiling 22v10 designs.
And finally, the PA file format has been extended to accommodate the
new library features, and PA files are now named according to a naming
convention for identifying devices.

New in 20001004:
- Major improvements to handling of binary files produced by HSPICE.
- Overhaul of input of spice3/ngspice raw files; more robust and tolerant
of complex numbers.
- User interface improvements: tooltips added. User's .gwaverc no longer
required to do lots of standard setup. system.gwaverc can be copied
to $HOME/.gwaverc and edited to taste.
- sp2sp utility included for converting any spice file readable by gwave into
a convenient tabular ascii format.
An exploit for a buffer overrun in the AFS dissector was recently
released on BugTraq. Ethereal 0.8.14 fixes this and other
possibly-exploitable overruns. Also new in 0.8.14 are dissectors
for WAP, SIP, AIM/OSCAR, 802.11, GIOP v1.2, and MGCP (plugin).
Other dissectors were updated as well. Be sure to upgrade to
0.8.14 as soon as possible

from the history file:
----------------------
New features:
1. New probes: diode G, mos IBD, IBS, GBD, GBS.
2. New options: "floor" and "vfloor". (Floor was in the manual, but
not in the simulator.)
Improvements, bug fixes, etc.
1. There is a change to the way behavioral modeling conditionals are
handled. It should now be 100% compatible with SPICE, considering the
subset that duplicates SPICE. There are still significant extensions
beyond SPICE, particularly that you can have behavioral resistors,
capacitors, inductors, etc.
2. Parameter default calculations are now done in a manner consistent
with Spice 3f5. Previously, it was supposedly consistent with Spice
2g6.
3. A bug in calculation of threshold voltage of the level 6 model, for
P channel devices, has been fixed.
4. A bug in calculation of Meyer capacitances when the device is
reversed has been fixed. This bug sometimes caused a discontinuity at
vds=0.
5. I have added some smoothing to the Meyer mos capacitor models.
This improves convergence. The down side is that sometimes the
answers are different. It is probably a little better, when
considering closeness to reality, but it is still Meyer's model.
6. MOSFET parasitic diodes are now the same as those used in Spice.
7. There are subtle changes in the diode model. I think this usually
improves convergence.
8. Charge calculation in Meyer capacitors and diode capacitiors is now
supposedly Spice 3 compatible.
9. An error in BSIM3 scaling has been fixed.
Some things that are still partially implemented:
1. Internal element: non-quasi-static poly-capacitor.
2. BSIM models, charge effects.
Bugs (nothing new, but needs repeating):
1. The transmission line initial conditions are not propagated until
the transient analysis runs.
2. The makefile does not set up the proper link for the model
compiler. You need to do it manually.
3. A bad setting of "vmax" and "vmin" can lead to convergence to a
nonsense result. It is not as bad now as it used to be.
