Hello everyone.

Imagine i have multi-core CPU (2 or 4, nevermind). Can i use all cores to accelerate a simulation in Modelsim?
 

No. Its only single threaded.

But AFIK, you can run Modelsim multiple times and each would run on a different core. This way, you'll be able to run multiple simulations at the same time.
 

That will work - just make sure you have plenty of ram and a decent disk!
 

And a lot of understanding co-workers that won't get upset when you are hogging all the licenses ;-)

I want to accelerate Modelsim's work speed, do not simulate a few models at the same time.

Using a faster machine, is the only way to do that.

Does it have "student edition" like Modelsim?

Questa has traditionally been the top level simulator that is the most expensive - but Im sure Ive seen things recently that they are trying to rebrand all modelsim under the questa name - so maybe?

I think that the key aspect to consider in HDL simulation is the parallelism of the application or more exactly lack thereof - parallelism.

A machine that runs at speed X (assuming speed X is possible and peripheral resources such as memory are abundant) will ALWAYS have higher performance then N machines running together at speed X / N.
The less parallelism the problem exhibits - the bigger will be the performance edge to the faster machine.

No. Modelsim remains as the student and entry level products.

I do not know can i ask here but today i get a problem with Modelsim. I use "student version" Modelsim 10.3d for Altera Quartus II, and today (after a half of year!) i get error 211.



Can someone tell how i can fix it?
 

That means Modelsim crashed. And from the messages it looks like it ran out of memory.
