APS, Multi-threading, High-Performance Simulation...

aditeman

Andrew,

 

I am a bit confused with all of the high performance simulation options in ADE-XL/GXL.

I am using IC 6.1.5.506 with  MMSIM 10.11.200

On ADE I have:

  1. "Options->Job Setup->Max Jobs"  

   2.  "Options->Run Options-> Run In"

  3.  "High-Performance Simulation->Mode, Multithreading options, Affinity"

  4. "Options->Analog->Multithreading Options"

Maybe others...

 

What is the up to date way to run my simulations as fast as possible?

The main reason I'm asking is that I've had some problems when setting things such as APS + Max Jobs=8. For example, I've had these settings and sent a small simulation with a few corners and after waiting 10 minutes it still hadn't started. In general, it seems to take minutes until simulations start running sometimes (and then they run very fast).

Any suggestions/explanations?

 

Thanks,

 

ADi

    Laurent,

    Provided you're using spectre from an MMSIM version later than (say) MMSIM71 (although that's pretty old - I suggest you use a release newer than 7-8 years old when  you have MMSIM72, MMSIM101, MMSIM111, MMSIM121, MMSIM131, MMSIM141, MMSIM151 and SPECTRE161 to choose from). If you do that, and are also using a later subversion of IC5141, then ADE will have a Setup->High-Performance Simulation form. If you enable APS, you have the choice of multi-threading.

    Certainly you should not use the spectre that came with IC5141, because that hasn't really been touched (other than a few bug fixes here and there) since 2004.

    Regards,

    Andrew.
