| Abstract(in English) | High switching activity occurs when the response to a test vector is captured by flip-flops during scan testing. This may cause excessive IR drop, resulting in significant test-induced yield loss. The paper addresses this problem with a novel method based on test set modification, featuring (1) a new constrained X-identification procedure that turns a properly selected set of bits in a fully-specified test set into X-bits without fault coverage loss and (2) a new LCP (low capture power) X-filling procedure that optimally assigns 0's and 1's to the X-bits to reduce the switching activity of the resulting test set in capture mode. This method can be readily incorporated in any test generation flow to efficiently reduce capture power dissipation without any impact on area, timing, test set size, and fault coverage. Experimental results on benchmark circuits have shown its effectiveness. |
