Abstract
A method of designing a circuit layout includes calculating a typical value representing performance characteristics for the circuit layout based on a graphic database system (GDS) file. The method further includes calculating an adjustment value based on the GDS file and at least one of a CAP corner vector or a RES corner vector, wherein the CAP corner vector is based on an eigenvector of a parasitic capacitance of the circuit layout, and the RES corner vector is based on an eigenvector of a parasitic resistance of the circuit layout. The method further includes calculating a corner value based on the typical value and the adjustment value. The method further includes modifying the GDS file if performance characteristics of the corner value fail to satisfy performance requirements of the circuit layout.
