ABSTRACT:
A method and system for performing dummy metal insertion in design data for an integrated circuit is disclosed, wherein the design data includes dummy metal objects inserted by a dummy fill tool. After a portion of the design data is changed, a check is performed to determine whether any dummy metal objects intersect with any other objects in the design data. If so, the intersecting dummy metal objects are deleted from the design data, thereby avoiding having to rerun the dummy fill tool.
