WebNov 27, 2002 · Myth #1: ATPG achieves better fault coverage than logic BIST. Using random patterns makes logic BIST unable to achieve the same level of stuck-at fault coverage as deterministic patterns. It is true that many designs will require a large number of random patterns to achieve high stuck-at fault coverages. WebDec 9, 2024 · IEEE Std. 1149.1 Boundary-Scan Testing: Image Intel.
