Hi everyone, I'm simulating an oscillator working around 3GHz and I did the pss simulation to get the frequency.
Yet I want the simulation result to be a bit accurate , for instance, to be within the accuracy of 10kHz, however, when I redid the simulation without changing anything, the resulting frequency fluctuated with about 100kHz at least, so my result seems to have little physical meaning.
I wondered what should I do to increase the simulation accuracy.
I read the cadence design manual, the sections on PSS options form. I tried change maxstep to 10p and steadyratio to 1e-8, but they never worked.
Thanks for any helpful advices.
