Abstract

A static compaction procedure to reduce test set size forscan designs and a procedure to order test patterns in order tosteepen the fault coverage curve are presented. The computationaleffort for both procedures is linearly proportional tothe computational effort required for standard fault simulationwith fault dropping. Experimental results on largeindustrial circuits demonstrate both the efficiency and effectivenessof the proposed procedures.
