Abstract

A test generation tool for combinational circuitscalled FATGEN has been developed based on the notionof fault tuples. FATGEN can be used to simultaneouslygenerate tests for many types of misbehavior that occurin digital systems. Individual experiments involvingSSL, transistor stuck-open, path delay and bridgingfaults for the ISCAS85 benchmark circuits reveal anaverage speedup of nearly 32% and test set compactionof 60% when faults of all types are analyzed simultaneously.In addition, there is an average reduction ofapproximately 34% in the number of aborted faults.
