Abstract

In order to generate correct at-speed scan patterns, the effect of timing exceptions and constraints needs to be considered during test generation. A path-oriented approach to handle timing exception paths during at-speed ATPG has been presented in [1][2]. The new method has been applied to and tested on many example circuits at Semiconductor Technology Academic Research (STARC). This paper presents a sample of these test cases, and illustrates how the proposed method generates correct-by-construction at-speed patterns on these circuits without pessimism.
