Diagnostic Fault Simulation of Sequential Circuits
Elizabeth M. Rudnick, W.K. Fuchs, Janak H. Patel · 2005
In this work we describe a diagnostic fault simulator for sequential circuits which evaluates the effectiveness of a given test set in distinguishing between faults. Diagnostic fault simulation is performed on several ISCAS89 sequential benchmark circuits using two different deterministic test sets for each circuit. Several diagnostic measures are reported, including the diagnostic resolution, the diagnostic power, and the sizes of the indistinguishable fault classes. In addition, lists of indistinguishable faults are generated. Use of the diagnostic fault simulator to diagnose faults, given the output responses of failing devices, is also described.
