This article presents an efficient method for multiple fault diagnosis of combinational circuits by sensitizing input-pairs. The diagnostic process uses five deduction rules and a progressive deduction procedure to deduce suspected multiple faults in a circuit without probing internal lines, based on the responses observed at primary outputs by sensitizing input-pairs. The authors present a detailed example to demonstrate their method and experimental results to show the efficiency of the method.
