Fault insertion methodology

Relevant procedures, information, and guidelines are presented to validate and verify the effectiveness of a test program. The major areas of discussion are the test-program development sequence, component stress, and fault-insertion guidelines. Fault insertion, defined as the temporary installation of component and pin fault failures in a unit under test (UUT), can be destructive to the UUT, interface adaptor, or automatic test equipment (ATE) used, and can also be hazardous to the ATE operator. A methodology that minimizes these unwanted results is presented.<
