Abstract
This disclosure is concerned with the use of on-line simulation of circuit faults during diagnosis to generate a small part of a complete fault dictionary needed for diagnosis of the circuit, being adapted for use of a mini-computer-based automated test system having only a small amount of secondary storage; and being adapted for an exact match diagnosis with modeled failures, and a heuristic approach for a partial match of faulty behaviour that leads to a highly probable diagnosis.
