Using Envelope OP for subsequent PSS

MicheleA

Hi,

can anybody point me to the way to implement this? I have a circuit which I would like to analyze the 'fast behaviour' of, however there are some large time constants in the circuit so that tstab renders design interaction sub optimal.

I can throw an ENV simulation to capture those slow transients and this works just fine, however analyzing the 'occasionally integrated clock cycle' is a bit cumbersome within the ENV frame. Unless, of course, I am not aware of some device for showing that ' occasionally integrated clock cycle' from ENV, much like you do with PSS when looking at *_td waveforms.

Therefore, my idea would be to run an ENV in the first place, then pass the final OP to PSS for a cycle or two.

I think there should be a possibility...maybe with Ocean scripting? But I am not savy at all in this field.

Can anybody point me to the manual or options I should study?

Thank you in advance,

Michele
