Verification Testing—A Pseudoexhaustive Test Technique

A new approach to test pattern generation which is particularly suitable for self-test is described. Required computation time is much less than for present day automatic test pattern generation (ATPG) programs. Fault simulation or fault modeling is not required. More patterns may be obtained than from standard ATPG programs. However, fault coverage is much higher—all irredundant multiple as well as single stuck faults are detected. The test patterns are easily generated algorithmically either by program or hardware.
