WebJul 18, 2008 · PSS analysis uses the shooting method to find the periodic-steady-state solution. The shooting method solves a boundary value problem by reducing it to the solution of an initial value problem. PAC analysis is used to compute transfer functions for circuits that exhibit frequency translation.

PSS requires that the circuit is not chaotic (periodic input leads to a periodic output). High Q circuits do not pose a problem to PSS

The PSS form must be set so that a pre trans run “tstab” is always performed. Extensive simulations have shown that, for difficult convergence oscillators, that the options designed to improve convergence, essentially, always fail.
