Different from conventional low-power BIST, this paper is the first to explicitly focus on achieving capture power safety with a novel and practical scheme, called capture-power-safe logic BIST (CPS-LBIST). The basic idea is to identify all possibly-erroneous test responses caused by excessive capture power and use the well-known approach of masking (bit-masking, slice-masking, vector-masking) to block them from reaching the multiple-input signature register (MISR). Experiments with large benchmark circuits and a large industrial circuit demonstrate that CPS-LBIST can achieve capture power safety with negligible impact on test quality and circuit overhead.}, pages = {2706--2718}, title = {On Achieving Capture Power Safety in At-Speed Scan-Based Logic BIST}, volume = {E97.D}, year = {2014}, yomi = {オン, ギョウセイ and カジハラ, セイジ and ミヤセ, コウヘイ} }
