Verilog Simulators

My apologies if this question is covered in an FAQ.

What (low cost, hopefully) products are available for simluating
Verilog for lightweight or medium-weight usage?

As a point of reference, I still have a copy of Veriwell
I purchased nine years ago, which would be suitable except
it is not up-to-date on language extensions since then.
So I'm looking for a similar, current product, for
either Windows, Linux, or both.

Thanks much

Steve

Free versions of ModelSim are available from Altera and Xilinx.

Thanks. According to the Xilinx site this only supports
Verilog 95, although that could be incorrect.

Icarus Verilog might suit you:
< http://www.icarus.com/pub/eda/verilog>

The 0.8 release has some of the easy 2001 constructs (C-style
port and parameter passing and declarations, for example) or you
can try the latest snapshots which are even more compile, even
with so features beyond standard Verilog (real values through
ports, logic and bool types, etc.)

Try out LogicSim, it's free for the time being. I'm constantly making
frequent updates to improve the Quality of Result. It supports
WinXP-platform, Verilog text editor, VCD, SDF, Verilog-2001,
multi-files project, and many more. However, no PLI/VPI and Waveform
editor support at the moment. I will release v1.9 somewhere this month,
it is going to be a very stable release. Thanks.

"Free versions of ModelSim are available from Altera and Xilinx."

The free version of Altera ModelSim and Xilinx ModelSim are not
available in their free web-editions, you need to purchase their
license (around $2000) to get the free ModelSim OEM version. Besides,
the performance of the OEM really sucks, and their limit in the size of
the design.

Umm, not exactly. Anyone may download and use the free ModelSim XE
"Starter."

The "non-Starter" ModelSim XE is $1000.

Besides, the performance of the OEM really sucks, and their limit in the size of
the design.
For small designs and for learning the languages, the free versions are
adequate.

Your tool may be fine, too, although your web site's pronouncement that
"since Verilog/SystemVerilog has clearly won the battle of HDL, the
future of VHDL seems vague" is rather bold.

We do intend to support VHDL in the future, but at the moment, we would
focus on Verilog/SystemVerilog. The end goal of LogicSim is a mixed
languages simulator.

Just curious.

Are you aware there is already an application called "LogicSim", which
is a graphical environment for simulating logic? It has existed (
according to the website ) since 1995 :

http://www.tetzl.de/alogicsim.html

They came out with a java version in 2001:

http://www.tetzl.de/java_logic_simulator.html

I am wondering why you would name your proprietary software tool with
same name as another tool, that arguably has similarities.

Your website, also contains images of Altera's Quartus Logo, and
Xilinx's ISE logo, in what looks like an endorsement or collaboration.
Do you have any affiliation with either of these organizations ?

Yes, we do realize there's an application called LogicSim too, however
they didn't register the domain so we did. Besides, that's more like a
university research application rather than a commercial one. It's a
logic primitives simulator (switches, gates, flip-flops, etc) which
can't be used in large scale design.
Hope as time passes by people would be less confused ...

No there's no affliations with Altera or Xilinx at the moment. The
reason their logos are our website is to show that LogicSim is more
fine tuned to FPGA enviroment than ASIC's at the moment. As for the
SystemVerilog logo is to show our commitment to support SystemVerilog
in the future.

Hope all this will answer your questions. Thanks
