摘要:This paper presents a delay measurement technique using signature analysis, and a scan design for theproposed delay measurement technique to detect small delay defects. The proposed measurement technique measuresthe delay of the explicitly sensitized paths with the resolution of the on-chip variable clock generator(VCG). Theproposed scan design realizes complete on-chip delay measurement in short measurement time using the proposedmeasurement technique and stores the test vectors using extra latches. The evaluation with Rohm 0.18- m processshows that the measurement time is 67.8% reduced compared with that of standard delay scan design on average. Thearea overhead is 23.4% larger than that of the delay measurement architecture using standard scan design, and thedifference of the area overhead between enhanced scan design and the proposed method is 7.4% on average.
