ATPG-based technique for reducing shift and capture power during scan testing is presented without any influence on fault coverage. This paper presents Adjacent Backtracing filling (AB-fillingl) which both adjacent and backtracing filling algorithms are used, is integrated in the ATPG algorithm to reduce capture power while feeding the first test pattern into CUT. After our approach for at-speed scan...
We present a Linear Feedback Shift Register (LFSR) like architecture, because the LFSR can bring a lot of data by using a few bits. We calculate the ATE data by Gauss-Elimination and put the ATE data to our decompression architecture to generate a lot of patterns. And one ATE data will run several times in the architecture. If some faults cannot be detected, we will generate the patterns which are...
A scheme that ATPG-based technique for reducing shift and capture power during scan testing is presented without any influence on fault coverage. This paper presents an X-filling approach called adjacent backtracing fill (AB-fill). After AB-fill approach for at-speed scan testing, all of test patterns have assigned as partially-specified values with a small number of don't care bits (x) as in test...
During built-in self-test (BIST), the set of patterns generated by a pseudo-random pattern generator may use longer time and more power consumption in testing. In this paper, we propose a novel hardware architecture base on "LBIST Controller" to reduce test application time and test power consumption. Give a test cubes for stuck-at faults contain unspecified bit generated by a sequential...
