In compare mismatch test, a series of un-equal test patterns are applied on inactivity monitor inputs. Un-equal vectors are expected to generate a compare mismatch and a compare match indicates a fault. If a compare match is found, self test error flag is set and a self test error is indicated. Self test is terminated as well. If all patterns are generating mismatch, self test complete flag (STC3) is set.
Table 6-170 shows the patterns used for compare mismatch test.
