Masking schemes typically suffer from over-masking of bits that may possess fault effect information, degrading test quality levels. Unknown response bits (x's) exhibit a clustered distribution in responses due to structural proximity of x sources. In this work, we propose a toggle-based masking scheme that is capable of delivering very high observability levels in the case of clustered x distributions. The proposed scheme assigns a single-bit state to each chain, dictating whether the chain… CONTINUE READING
