Ultrasim: individual accuracy setting on subcircuit level ?

baenischfau

Hi all,

 

I'm currently simulating a big mixed signal block, consisting of two big blocks. The instance block I0 is

pure digital logic, instance I1 is mainly analog but also includes some digital parts. I'm using Ultrasim

for verification but due to the analog parts I'm forced to use a quite strict accuracy setting to get the

results about right. However this setting is killing the digital part ...

 

I know that some other simulators offer the possibility to define accuracy levels for each instance in

a design, e.g. set I0 to Digital Fast and I1 to Analog. Is something like this possible with Ultrasim ?

 

Best Regards

     Hi Andrew,

     

    Thank you very much. Found it and trying it right now. 

    However I'm puzzled by one simulator output. Even though I set one instance to df and one to s

    the device model statistics reports only devices set to spice. Shouldn't there also be devices listed

    that are set to df ? I'm using MMSIM 12.11.115 

     

    Best Regards
