Abstract

A method, system and program product for migrating an integrated circuit (IC) design from a source technology without radical design restrictions (RDR) to a target technology with RDR, are disclosed. The invention implements a minimum layout perturbation approach that addresses the RDR requirements. The invention also solves the problem of inserting dummy shapes where required, and extending the lengths of the critical shapes and/or the dummy shapes to meet ‘edge coverage’ requirements.
