Abstract

This paper considers the design of diagnosable combinational networks. The diagnosability criterion used here requires that the single fault detection test set for the network also detects all multiple faults. Several recent studies in the area of multiple fault diagnosis are reviewed and the results which are pertinent to this investigation are summarized. It is shown that, under certain conditions, internal fan-out may be present without adversely affecting the detection of multiple faults. These results suggest design techniques which lead to readily diagnosable networks.
