How to speed-up simulation

Hi,

 

I'm using Vivado 15.3 Simulator in order to simulaten a full project. It's very slow, it takes 01:15 minute to simulate 50us.

 

How can I speed up the simulation?

should i use a third-party simulator? should i purchase a special liscence?

 

Thanks,

Danna

Re: How to speed-up simulation

HI @dannna

 

DO you mean to say it takes 1hr : 15 mIn  for 50 us of Post PAR simulation?

If your design has a good amount of DSP48, MMCMs or GTH utilization, You can try using unifast simulation models for the same.
Refer page 22 of  Logic simulation guide for usage details.

Re: How to speed-up simulation

Hi Danna,

 

There is no other license provided by Xilinx to speed up the simulation.

 

Thanks and Regards,

Re: How to speed-up simulation

If don't want to monitor any signal on waveform, please run simulation by change the debug level to 'OFF' from simulation setting under elaboration tab.

 

Also I would like to see what's causing simulator to run slow or is it because of design. Will it be possible for you to share  design.

Re: How to speed-up simulation

Hi,

 

Thanks for the tip.

 

I mean that it takes 1 minute and 15 seconds to simulate 50us.

I checked for errors and collisions in the log and didn't find any.
