A new approach for dynamic test vector compaction, for combinational logic circuits, called COMPACT, is proposed. A new data structure of test vectors permits easy verification of compactability between test vectors with minimal memory requirements. Experimental results obtained by adding the proposed algorithm to a simple PODEM program and applying it to the ISCAS-85 benchmark circuits are presented. The resulting test vector reduction is up to 40% for small circuits and around 50% for the large circuits (over 1000 gates).>
