Abstract
A method of training an Optical Proximity Correction (OPC) model comprises symmetrizing a complex design to be a test pattern having orthogonal symmetry. Symmetrizing may comprise establishing a axis of symmetry passing through the design, thereby dividing the design into two portions; deleting one of the two portions; and mirror-imaging the other of the two portions about the axis of symmetry. The design may be centered.
