[edit] Does this really need to be its own article?

Does this really need to be its own article? This seems to duplicate some effort in the Verilog page. If it does make sense to make this a page of its own, perhaps the Verilog article should be coordinated with this by adding a link here.

[edit] Full disclosure

It turns out that the author of this article, ngsayjoe, is affiliated with the zeemz tool listed here, so I guess that it is not accident that it is the "most user friendly and affordable" tool on the list. This person has also appeared comp.lang.verilog performing similar stealth marketing.

My independence may also be suspect because I'm the author of Icarus Verilog, which is also on this list. I'll remove the "most popular" for that entry because whether it is true or not (I have opinions that I'll keep to myself) it doesn't belong there without references.

[edit] Disclosure

Sorry that I failed to disclose that. Yes, I'm the author of LogicSim. Being an expert in this area, I think I'm deemed appropriate as a person who creates this list as a draft. Anyone is free to modify whatever I write, as this is Wikipedia. I tried to provide an unbiased viewpoint from my point of view. This list was not meant to be used as marketing tool as claimed by Stephen, otherwise I wouldn't have listed other commercial and open-source simulators side-by-by unbiased. The creation of this list is necessary in order to provide an unbiased view point of Verilog simulators, as most blogs or websites found on the Internet will only provide their own preferences and views. Besides most Verilog simulator lists available on blogs or websites are usually incomplete or biased. So here goes the Wiki entry of its own. Hope this list will continue to grow and improve as time passes.

[edit] verilog expert

who ? Ngsayjoe ? You maybe an expert in your own implementation of Verilog/System verilog. The real test is in real world design. Everyone can claim being an expert. By the real experts in Verilog simulation are yet to claim they are one. Your should let your product do the talking. Let your simulator proves you right, So far, no luck.

[edit] Chonguantan --> from Mentor Graphics?

Chonguantan you seem to be talking on behalf of Mentor Graphics your employer?

=== chongguan tan sorry, somehow wiki keeps appending to this posting.

I can't speak for Mentor Graphics. I speak from my heart. As an ex-simultor R&D engineer and user, I know what is good and what is bad. I can only honestly classify Modelsim as "1 of the 3 dominating simulators".

I am no Verilog Expert, and don't pretend to be one.

It truelly sucks to see the simulators arranged alphabetically. "important" to the industry should be the main factor, and 'year entering market' should be the second. It really sucks to see Verilog-XL buried at the end of the list,

[edit] SystemVerilog & VCS

Having worked on the GUI used by Synopsys, I can understand how they were able to integrate SystemVerilog quite quickly. The VCS GUI was developed independently of the simulator, (by Simulation Technologies, later Summit Design )and was designed to be able to work with different simulators and different HD Languages (concurrently, no less). With SystemVerilog being just another simulator using just another language, developing the software wrapper to integrate the simulator into the VCS GUI wouldn't have been a monumental task. --64.238.49.65 (talk) 13:43, 25 March 2008 (UTC)

[edit] This is a list

>> It truelly sucks to see the simulators arranged alphabetically

This is a list of simulator vendors, henceforth it should be arranged by order of alphabetics, just like any other lists on Wikipedia.

Example, http://en.wikipedia.org/wiki/NASDAQ-100

If you write a review, then you may like to arrange it in whatever order you like.

[edit] Biased list

Somebody really needs to take out some of the "opinion" information. Come on here. A simulator is "maybe the best among the big 3" and another one is "getting its butt kicked real bad by the competitions?" Does somebody have facts to back up these opinions?

Also, it would seems to be accpetable to me to break the list up into "Dominant Players (big 3)," "Open Source," and "Others."

...

"Big 3", to me, means those simulators actively validated for ASIC tape-out signoff at major foundries. None of the smaller players have that level of qualifcation, so no (modern) ASIC design team would dare run gate-level simulations on anything other the big-3 simulators.

The FPGA-market has a different set of players, and focus more on suite-integration (state-diagram editor, automatic waveform generation for documentation/testbench automation, push-button launch of FPGA-synthesis engine, etc.)
