Abstract

The presence of unknown values in simulation is the great est barrier to effective test response compaction. For space compactors, some responses may not be observable due to the masking effect caused by unknown values. This paper reports on experiments conducted to evaluate the impact on the test quality of various percentages of observable responses for both modeled and un-modeledfaults.
