Hi guys,

I used the method from this website for my switch capacitor filter simulation. When I used the method the pss faced the convergence problem, and I increase the stb time, however, it doesn't work. Then, I change the option that figure the cmin for convergence to 1e-18F. The pss simulation could work without convergence issue, but PAC face the problems as the error showed below. It seems that the operation-point is not write. I'm wondering how to solve the problem and continue the PSS and PAC simulation?

"Using the operating-point information generated by PSS analysis 'pss'
Analysis 'pac' terminated prematurely due to error"

Thank you!!!!

Hugo

Thank you very much and I have already read your reply but I am wondering how to turnon a strobing? It's the same simulation or other assisted simulators?

And also I have already came to PSS convergence but the PAC can't work uder the PSS output operation-point, so what's the problem? Have you ever met this issue?
