Hi All - I noticed the website for Icarus Verilog (www.icarus.com)
appears to be down.
Does anyone know if/when it will be back up?
IIRC, Steve's currently on vacation abroad so maybe his machine
crashed. I'm sure someone's mirrored his tarballs/binaries somewhere.
A mirror copy is in:

I try to understand how it is working for 2 specific cases.
It has a grammatical rule :
statement -> ...
| K_if '(' expression ')' statement_opt %prec
| K_if '(' expression ')' statement_opt K_else statement_opt
As far as I know from compilers theory (and Left to Right Bottom Up
parsing, as also Icarus Verilgo it is), the above rule should throw
conflict, because, the 2 options of the rule have the same prefix
(e.g. s -> s1 ) ( | s1 s2)

Can I save the state of a simulation using Icarus Verilog simulator?
I found the $save command in Google, but it doen't seem to work in
$save1: This task not defined by any modules. I cannot compile it.
ta_test: Program not runnable, 1 errors.
Any alternatives in Icarus?

Not sure! As for me , I would *never* use a synthesizer that was not
supported in some way for any serious. Not to trash the hard work that
was put into Icarus Verilog. Its hard enough trying to track down my own
bugs, let alone somebody elses.
Some things are worth paying for a *team* of engineers to do.
That being said, having free tools are nice. But this is a non-issue
now. I think just about all of the majo...Icarus Verilog for Windows
I will be maintaining recent snapshots of the Icarus Verilog compiler
for the Windows platform in easy to use installers at
http://armoid.com/icarus/. I have been doing this for more than a year
now for the people in my company so I thought, what the heck, for the
same effort I can benefit other users out there.
If you have other free related goodies that can be posted there
--like Verilog test files, utility scripts, etc.-- please email me at

I wanted to know if the latest snapshot of iverilog is working with n-
dimensional arrays (n > 1).
...Icarus Verilog opinions
I've been trying out the Icarus Verilog compiler/simulator. It
looks nice so far. Any views on it?
Also, it claims that it can generate code to load onto real
FPGA's. Can it really do that? Has anyone tried it? I'm
interested in Altera devices.

I'm trying to make a FORCE statement work in Icarus, but it gives me
I want to force a value to a node deep into a hierarchy. The force
statement works on the value itself, but it has no effect on
subsequent calculations. E.g. if I force the input of a simple gate
somewhere in the hierarchy, I would expect its output to change value
to satisfy whatever input->output relation that might exist.
I made the following code for a simple example:

I'm fairly new to verilog and I'm getting a strange error when I'm
compiling my code.
During compilation it just outputs: "Segmentation Fault", without
mentioning anything about what module or line it's occurring.
Anyone know any common mistakes that could cause such an error?

I really like the idea of using Icarus Verilog as a Synthesis tool in
our FPGA flow.
I have only used it with a few small test cases.

When I use iverilog for compiling structural verilog code that has no
"always" or "initial" blocks, but only wires and "assign" statements,
I get the error:
invalid module item. Did you forget an initial or always ?
Why is this so?

I would like to monitor an event monitor to make sure that I get an alarm
if it's not running. I would like to use SQL statements for this.
Is there a way to determine the current status on an event monitor, using
SQL? - syscat.events doesn't seem to expose the status of the event
