Classical scan designs require properly augmented flip-flops, often called scan flip-flops. Problems stem from the high areaoverhead implied by the need for these flip-flops or the inability to modify standard flip-flops. The authors outline a methodto design easily testable sequential circuits that achieve scan designs using standard (unmodified) flip-flops.
