Running Spectre Stability Analysis at a non-Quiescent operating point.
Jun 25^th, 2009, 3:06pm

I'd like to run a transient analysis on this circuit up to 100nS and THEN perform a stability analysis under that operating point. Does anyone know if this can be done? Kundert's book mentions it with AC analysis but I cant get this to work with STB since the STB run happens BEFORE transient... at least that is the first problem.

Thanks.

Reply #2 - Jul 8^th, 2009, 6:37am Dear Kevin, Are you running simulation through ADE ? Then you can try like this . : analyses -> tran -> option -> actimes = 100 n acname = stb. In your analysis section both tran and stb should be enabled properly. and then you run the simulation.
