ALIASING COMPUTATION USING FAULT SIMULATION WITH FAULT DROPPING

It is generally thought that accurate analysis of aliasing requires no n-fault dropping fault simulation. We show that fault dropping is poss ible when computing the exact aliasing of modeled faults for common ou tput response compression circuits. The fault dropping process is most effective when the test set size is small. Extensions to large test s ets are also considered. We present a fault simulation procedure that takes maximum advantage of fault dropping and present experimental res ults to support its effectiveness.
