Abstract

Manufacturing testing becomes increasingly difficult in the nanometer manufacturing region because of the impacts of process variation on path delays. It has been frequently observed from manufacturing testing that different chips exhibit different speed limiting paths; and different set of paths may fail to meet the timing specification for different chips.
