| Abstract(in English) | This paper presents a new approach to multiple fault diagnosis in sequential circuits by using input-sequence pairs having sensitizing input pairs. We call such the input-sequence pair the sensitizing sequence pair in this paper. First, we generate sensitizing sequence pairs from a test sequence detecting a single stack-at fault in a sequential circuit and use a set of sensitizing sequence pairs to diagnose multiple faults in the sequential circuit. Next, we describe a method for diagnosing multiple faults in sequential circuits partitioned into sub circuits. This represents an extension of our previous work dealing with combinational circuits. From a relation between a sensitizing path generated by a sensitizing sequence pair and a subcircuit, this method deduces the suspected faults for the subcircuits, one by one, based on the responses observed at primary outputs. Finally, we study the efficiency of the method from experimental results for benchmark circuits. |
