    Mixed-Signal Simulation Speed Optimization Reply

    After spending some time to setup a mixed-signal simulation, I reached a point where I can no longer increase the simulation speed. The chip core is referencing behavioral VHDL and a majority of the analog modules are represented by Verilog-A code. I am simulating using irun. I was wondering it if would be possible to see which part of the IC is slowing down my simulation? I have also noticed that when I represent some modules in Verilog-A, it can slow down the simulation. I'd like to have a better understanding of which modules are doing what.

    I am using mmsim710 and ius82.

    Hi TjaartOpperman

    It might be easier to simply upgrade your IUS82 to the latest INCISIVE12.1 and use multi-cpu AMS-APS to see if it helps.Your current packages are quite out-dated. By the way, when running mixed-signal simulations, only INCISIVE package is used, not MMSIM package.

    For your information, you will need RHEL5.5 in order to run INCISIVE12.1. IUS package has been renamed as INCISIVE.

    Best regards
