PSS simualtion for oscillator in ocean script
Feb 16th, 2007, 7:42am
 
I would like to run PSS simulation for oscillator over corners using ocean script.
How can I include the simulation in the script?

E.g. PSS setup in the netlist is as follows (mclk is the node where oscillation is measured):
___________________________________________
pss  (  mclk  0  )  pss  fund=75k  harms=60
+    errpreset=conservative  tstab=100u  saveinit=yes  method=trap
+    annotate=status
___________________________________________

Normally I would use "analyses" and "run" statement in the script.
E.g. for transient:

___________________________________________

analysis('tran ?stop "200u"  ?errpreset "conservative")
run()
___________________________________________

However I always get error emssage when I try to combine these two..
Something like "undefined function" etc.

What's the proper way of doing it?

Well, it would help if you actually showed what you'd tried, and the actual error message.

The easiest way to get a starting point for your OCEAN script is to set it up in ADE, and use Session->Save OCEAN Script.

Regards,

Andrew.
