Line Oriented Structural Equivalence Fault Collapsing

Abstract

This paper presents a new perspective on structural fault collapsing at the gate level. As compared with current structural fault collapsing methods, a method based on this point of view enables a faster and optionally a more reduced fault collapsing. In addition, our new fault collapsing method is easily implementable in the VHDL language. Performance improvement of this method has been verified using ISCAS benchmarks. 1.
