— This paper proposes a two-dimensional scan shift control concept for multiple scan chain design. Multiple scan chain test scheme provides very low scan power by skipping many l...
Keeping diagnostic resolution as high as possible while maximizing the compaction ratio is subject to research since the advent of embedded test. In this paper, we present a novel...
Diagnosis is increasingly important, not only for individual analysis of failing ICs, but also for high-volume test response analysis which enables yield and test improvement. Sca...

In this paper, we present test generation procedures to improve scan chain failure diagnosis. The proposed test generation procedures improve diagnostic resolution by using multi-...

Scan is a widely used design-for-testability technique to improve test and diagnosis quality, however, scan chain failures account for almost 50% of chip failures. In this paper, ...
