Abstract

See full text

A computing system may include a metal stack tuning engine and a tuned metal stack application engine. The metal stack tuning engine may be configured to access an obscured metal stack definition specified for an integrated circuit (IC) manufacture process and tune selected metal stack parameters of the obscured metal stack definition to obtain a tuned metal stack definition. The metal stack tuning engine may do so by generating sampled metal stack definitions, constructing sampled layout geometries from the sampled metal stack definitions, computing parasitic capacitance value sets for the sampled layout geometries, and determining tuned values for the selected metal stack parameters through a curve fitting process. The tuned metal stack application engine may be configured to use the tuned metal stack definition to perform a parasitic capacitance extraction process for an input IC design.
