PSUD can't be used to assess ringing other than at an extremely rudimentary level. For one thing, ringing of the PSU can be caused by excitation from either the source or load, and there is no provision for that in PSUD. For another, the amplitude of the PSU response to excitation will vary as a function of frequency. PSUD does not allow inputs other than the three line-frequency choices, and there is no provision for a dynamic load other than the simplistic step function. If you want to analyze the response of the PSU in this regard, a more versatile simulator is required.
