From a large pool of diverse available techniques for compression, run length-based schemes are most appropriate for IP cores. To improve the compression and to reduce the test power, the test data processing schemes like \u201cdon't care bit filling\u201d and \u201creordering\u201d which do not require any modification in internal structure and do not demand use of any test development tool can be used for SoC-containing IP cores with hidden structure. The proposed \u201cWeighted Transition Based Reordering-Columnwise Bit Filling-Difference Vector (WTR-CBF-DV)\u201d is a modification to earlier proposed \u201cHamming Distance based Reordering\u2014Columnwise Bit Filling and Difference vector.\u201d This new method aims not only at very high compression but also aims at shift in test power reduction without any significant on-chip area overhead. The experiment results on ISCAS89 benchmark circuits show that the test data compression ratio has significantly improved for each case. It is also noteworthy that, in most of the case, this scheme does not involve any extra silicon area overhead compared to the base code with which it used. For few cases, it requires an extra XOR gate and feedback path only. As application of this scheme increases run length of zeroes in test set, as a result, the number of transitions during scan shifting is reduced. This may lower scan power. The proposed scheme can be easily integrated into the existing industrial flow.<\/jats:p>","DOI":"10.1155\/2011\/756561","type":"journal-article","created":{"date-parts":[[2011,10,5]],"date-time":"2011-10-05T19:03:53Z","timestamp":1317841433000},"page":"1-8","source":"Crossref","is-referenced-by-count":3,"title":["Weighted Transition Based Reordering, Columnwise Bit Filling, and Difference Vector: A Power-Aware Test Data Compression Method"],"prefix":"10.1155","volume":"2011","author":[{"given":"Usha","family":"Mehta","sequence":"first","affiliation":[{"name":"PG (VLSI Design), Nirma University, Ahmedabad 382481, India"}]},{"given":"K.
