A Unified DFT Approach for BIST and External Test

Abstract

This paper presents a partial reset technique for testability improvement of non-scan sequential circuits. Both pseudo-random BIST and deterministic External Test are in the scope of this paper. The partial reset technique is used to improve hard-to-detect fault activation. This DFT approach is completed with classical insertion of observation points in order to improve fault propagation. Numerous experimental results on ISCAS'89 benchmark circuits show that 100% fault efficiency can be achieved at low cost.
