Summary :

A single bridging fault location technique for CMOS combinational circuits is proposed. In this technique, the cause of an error observed at the primary outputs in deduced using a diagnosis table constructed from the circuit under test and the given tests. The size of a diagnosis table is [the number of gates][the number of tests]2 bits, which is much smaller than that of the fault dictionary. The experimental results show that the number of possible bridging faults is reduced to less than 5 in several seconds, when using the tests to detect single stuck-at faults and considering only the bridging faults between physically adjacent nets.
