Module grouping to reduce the area of test wrappers in SoCs

Abstract

The number of wrapper cells which need to be added to SoCs for modular testing can be reduced by grouping modules so that they share wrappers. Such grouping may often increase test volume, which can be reduced by redesigning scan-chains and selectively eliminating some wrappers from the input and output ports of grouped modules. In experiments on benchmark… (More)
