Abstract

For hybrid fault situations (that is, bounded combinations of permanent and intermittent faults) in a classical PMC diagnosable system [1], the identification of faulty units has heretofore required that testing be patiently and perhaps unrealistically repeated until the test results obtained are consistent with permanent fault situations. As a consequence, intermediate test results go unused. Moreover, the occurrence of test results consistent with permanent fault situations will, in generaL, be a rare event.
