Abstract:This paper presents a logical fault model, the single gate logical fault with Hamming distance 1 (HISGLF) model, designed to enhance the defect coverage of test sets. Although some characteristics of the HlSGLF model are similar to those of the single stuck-at fault (SSAF) model, a test set derived from the HlSGLF model is capable of covering more defects than one derived from the SSAF model. Most of the existing ATPGs for the SSAF model can be easily modifled for the HlSGLF model. Experimental results show th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
