We present a new algorithm for discretizing interconnects, a step that is typically performed to account for the nonuniformity of current flow at high frequencies. The algorithm is based on an easily-computable measure that correlates well with the model accuracy. This measure is used to refine the discretization of interconnects in an adaptive scheme so as to systematically trade off computation against model accuracy. We apply the proposed discretization technique on two classes of problems in the analysis of VLSI interconnects: simulation and frequency-dependent inductance extraction. Numerical results establish that with the interconnect discretizations generated by our algorithm, a reduction in simulation and extraction times by a factor between three and seven can be realized with negligible sacrifice in model accuracy ( 1% error).
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.
