Abstract
Pattern data that is an object of correction is divided into an area on which correction is made using correction values that have been obtained in advance for patterns and their respective layouts and an area on which correction is made on the basis of correction values calculated by a simulator. For example, simulation-based correction is made on a gate layer in a memory, while rule-based correction is made on a gate layer in the other area than the memory on the basis of rules for active gate width only. After being subjected to the correction, the areas are combined.
