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, ...
Diagnosing failing vectors in a Built-In Self Test (BIST) environment is a difficult task because of the highly compressed signature coming out of the Multiple Input Shift Regist...
— This paper proposes a selective pattern-compression scheme to minimize both test power and test data volume during scan-based testing. The proposed scheme will selectively supp...
