Claim One:
1. In a computerized simulation model for analyzing composite logic circuits having devices for switching significant amounts of current, a system for detecting and diagnosing noise caused by current switching comprising: (a) logic simulation means for simulating logic experiments and for retaining and communicating results thereof; (b) noise contributor information file generating means for providing identification data corresponding to each current switching device that contributes noise and for enabling post analysis of the results said simulation; (c) a noise activity file generator connected to said logic simulation means for employing said simulation results to create an activity file of events that represents the operation of those current switching devices identified by said noise contributor information file generating means; and (d) a noise calculator-analyzer connected to said noise activity file generator for determining the amount of noise created by each noise contributing current switching device and for measuring the total instantaneous noise at each event in said activity file.
