Abstract:Commercial multi-threshold standard logic cell libraries are designed for nominal super-threshold circuits. If blindly used at near-and sub-threshold voltages, such libraries exhibit excessively coarse granularity in driving strength, leading to sub-optimal logic synthesis and placement-androuting results. To tackle this problem, a holistic methodology for designing a near-and sub-threshold standard cell library that has fine driving strength granularity is presented in this paper. Meanwhile, the proposed meth… 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.
