Abstract :
An approach of diagnosing single bridging faults in CMOS combinational circuits is proposed. In this approach, the cause of an error observed at the primary outputs is deduced using a diagnosis table constructed from the circuit under test and the given tests. The size of a diagnosis table is proportional to [the number of gates]×[the number of tests], which is much smaller than that of the fault dictionary. The experimental results show that the CPU time is nearly proportional to the size of the circuit and the resolutions for most faults are less than 100, when using the tests to detect single stuck-at faults
