A method and apparatus for determining how well a photolithographic model simulates a photolithographic printing process. A test pattern of features is printed on a wafer and the shape of the printed features is compared with the shape of simulated features produced by the model. A cost function is calculated from the comparison that quantifies how well the model simulates the photolithographic printing process.
