Abstract:
A design rule generation system comprising:(a) an automatic wiring pattern generation part that automatically generates a wiring pattern comprised of a combination of a wiring width and a space width between said wirings; (b) an optical simulation part that performs an optical simulation under a condition of printing said wiring pattern on an object, and outputs data of an exposed light on said object; (c) a finish prediction part that predicts a finished size of said wiring pattern to be formed on said object, based on said data of said exposed light; (d) a matrix database construction part that records, on a data table in the form of a matrix, resolvability of a plurality of said wiring patterns having a different combination of said wiring width and said space width which are obtained by repeating the respective operations in said parts (a) to (c); judges whether said finished size satisfies a predetermined condition or not, so that it is determined said wiring patterns are resolvable if said predetermined condition is satisfied, and determined said wiring patterns are unresolvable unless said predetermined condition is satisfied; and records the resolvability of said wiring pattern on said data table, so as to correspond respectively to said combinations of said wiring width and said space width; and (e) a design rule generation part that generates a design rule by defining a range of a resolvable region comprised of a set of said wiring patterns being resolvable, or an unresolvable region comprised of a set of said wiring patterns being unresolvable, based on said data table.
