摘要

A method for DRC verification of a design layout file comprising off-grid patterns includes identifying an off-grid pattern having one or more off-grid sides, outwardly expanding the one or more off-grid sides to adjacent grids to obtain a first on-grid pattern, inwardly contracting the expanded one or more sides of the first on-grid pattern to adjacent grids to obtain a second on-grid pattern, and performing a DRC verification on the second on-grid pattern using an existing on-grid DRC deck. The method also includes making a backup copy of the design layout file prior to converting the identified off-grid pattern into an on-grid pattern.
