We propose a method for reducing test data volume of integrated circuits or cores in a System-on-Chip. This method is intended to reduce the required number of Automatic Test Equipment (ATE) output channels compared to the number of scan-in input pins in a classical multi-chain implementation (horizontal compression). Compression and decompression are based on arithmetic operations and structures which present a very low area overhead. The proposed compression scheme does not impact the fault coverage achieve…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
