Abstract: 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.

Abstract: A shape-based layout beautification operation can be performed on an IC layout to correct layout imperfections. A shape is described by edges (and vertices) related according to specified properties. Each shape can be configured to match specific layout imperfection types. Corrective actions can then be associated with the shapes, advantageously enabling efficient formulation and precise application of those corrective actions. Corrective actions can include absolute, adaptive, or replacement-type modifications to the detected layout imperfections. A concurrent processing methodology can be used to minimize processing overhead during layout beautification, and the actions can also be incorporated into a lookup table to further reduce runtime. A layout beautification system can also be connected to a network across which shapes, actions, and IC layout data files can be accessed and retrieved.
