Abstract:A multilayer routing system usually adopts multiple interconnect configuration with different wire sizes and thicknesses. Since thicker layers of metal lead to fatter wires with smaller resistance, the layer assignment (LA) of nets has a large impact on the interconnect delay. However, such layer-dependent characteristics have been ignored by most of the state-of-the-art academic LA methods. These characteristics also weaken the previous wire length-based antenna avoidance method, because the net length itself… 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.
