Abstract
A method and computer system are provided for checking integrated circuit designs for design rule violations. The method may include generating a working design data set, creating a wafer image data set, comparing the wafer image data set to the design rules to produce an error list and automatically altering the working design data set when the comparing indicates a design rule violation. The method further automatically repeats the creating, the comparing and the automatically altering until no design rule violations occur or no solution to the errors exists.
