Abstract: A method and system for redesigning layouts adjusts polygon data to develop a new layout which meets new design rules. Polygon data defining the original layout is further broken down into equated layers which are logical combinations of the layers in the original layout. The further broken down data is typically in the form of rectangles, and associated information regarding how that particular rectangle was formed by logical combinations of layers. This further broken down information is then moved to conform to the new design rules, and the moves are checked against a technology file to ensure that the particular movement can be made.
