save option not working for ac within transient

Steve Mikes

I'm running a transient sim and using the actimes option to run ac analysis at various points. 

 

 tran_ac tran stop=150u errpreset=moderate write="spectre.ic" method=trapgear2 \

     writefinal="spectre.fc" annotate=status flushtime=60 \

     strobeperiod=250n save=selected \

     maxiters=5 acnames=[ac_single] actimes=mytimes

ac_single ac freq=frf annotate=status save=selected

save VCAP V1:p

 

The ac analyses that are run do not seem to be able to "find" the save statement in the netlist. When save=selected doesn't find any selected nets, it reverts to save=allpub, so I end up with all voltages and don't have the current I wanted. If I change the save in the ac analysis to save=none, I get nothing, so it does respond to the statement. Right now as a work-around I set save=lvl nestlvl=1 to filter out most of what I don't want, but this is still less than optimal. Am I missing something, or is this just a bug? Thanks!

  • It's a bug (I reported the issue a few years ago, CCR 772109). I thought it had not been fixed yet, but having re-checked, it's fixed in MMSIM12.1 (I tested in ISR12, so I'm not sure quite when it was fixed). It's definitely broken in MMSIM11.1, so it has been fixed relatively recently.

    Can you try MMSIM12.1 (you didn't say which version you're using)?

    Kind Regards,

    Andrew.
