Fault detection in combinational circuits using a statistical approach
Abstract
Deterministic approaches to fault detection in combinational networks require that a set of inputs be applied to a circuit suspected of being faulty and that the corresponding outputs be compared to those of the nonfaulty circuit either by simultaneously applying the inputs to a nonfaulty copy of the circuit or by storing the correct outputs of the circuit in some list. A proposal that statistical analysis of the outputs be used to detect the presence of faults, is presented. It is shown that if the set (or sets) of input probabilities are chosen judiciously, a fault in a combinational network will change the expected value of the means of the outputs significantly enough to determine that a fault has occurred. Criteria for selecting input probabilities, establishing testing procedures, and evaluating test results are discussed.
