Abstract

Apparatus for providing semiconductor device with an analysis module to receive device information, a G-function processor producing an ordered relationship representation corresponding to an optimization parameter specification, and a power cell optimizer to produce an optimization parameter from the ordered relationship representation. A method for designing a semiconductor device includes receiving an optimization target specification; receiving an optimization parameter specification corresponding to an optimization parameter; receiving the target parameter; receiving a G-function corresponding to an ordered relationship representation; optimizing the optimization parameter specification as a function of the predetermined G-function; and producing at least one optimized geometric layout parameter (GLP) by the optimizing, wherein the at least one GLP corresponds to an optimized power cell.
