Abstract
A method of generating a vector set, said vector set being used for testing sequential circuits. The method comprises selecting a plurality of fault models, identifying a fault list each for each of said plurality of fault models, identifying a vector set each for each of said fault lists, selecting a tolerance limit each for each of said fault lists, thereby each fault model having an associated fault list, an associated vector set and an associated tolerance limit, compacting each of said vector set such that the compacted vector set identifies all the faults in the associated fault list or a drop in fault list coverage is within the associated tolerance limit; and creating a vector set by combining all vector sets compacted. A system and a computer program product for testing circuits with a compacted vector set where the compacted vector set is created by dropping faults based on a tolerance limit.
