Abstract

See full text

A system for detecting and diagnosing noise caused by current switching in a computerized simulation model for analyzing composite logic circuits. The system includes a logic simulator for simulating logic experiments, a noise contributor information file generator for providing identification data corresponding to each current switching device that contributes noise and for performing post analysis of the results of a simulation, a noise activity file generator for creating an activity file of events derived from the simulation results, that represent the operation of current switching devices identified by the noise contributor information file generator and a noise calculator-analyzer 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 the activity file.
