Multithreading not working

Rob Gregoire
Rob Gregoire over 10 years ago

I'm simulating a 15 stage SAR ADC and even though the output log indicates that 4 processors are used with multi-threading I am not getting a reduction in Elapsed Time compared to CPU time. I even tried it with a couple ADCs in parallel to make sure the ADC is big enough but I still get no improvement.

It seems to be related to the process design kit. I can simulate a similar ADC in another process and get speed improvement. I'm using IC 6. Any ideas on what to check or what would be helpful in debugging? My internet search only turned up a question from 2006 that indicated that it doesn't work with some CMOS models.

    No. The first (limited) release of APS was in MMSIM7.1 (DC and transient only). Given that MMSIM7.0 was released in 2007 (so more than 7 years ago), and there have been 7 major releases of the simulator since then), why would you want to use such an old version? It makes no sense at all.

    Regards,

    Andrew.
