We present an approach to prevent overtesting in scan-based delay test. The test data is transformed with respect to functional constraints while simultaneously keeping as many positions as possible unspecified in order to facilitate test compression. The method is independent of the employed delay fault model, ATPG algorithm and test compression technique, and it is easy to integrate into an existing flow. Experimental results emphasize the severity of overtesting in scan-based delay test. Influence of different functional constraints on the amount of the required test data and the compression efficiency is investigated. To the best of our knowledge, this is the first systematic study on the relationship between overtesting prevention and test compression. 相似文献

Fault equivalence is an essential concept in digital design with significance in fault diagnosis, diagnostic test generation, testability analysis and logic synthesis. In this paper, an efficient algorithm to check whether two faults are equivalent is presented. If they are not equivalent, the algorithm returns a test vector that distinguishes them. The proposed approach is complete since for every pair of faults it either proves equivalence or it returns a distinguishing vector. The advantage of the approach lies in its practicality since it uses conventional ATPG and it automatically benefits from advances in the field. Experiments on ISCAS’85 and full-scan ISCAS’89 circuits demonstrate the competitiveness of the method and measure the performance of simulation for fault equivalence. 相似文献
