摘要
A method and system of representing geometrical layout design data having a plurality of polygons in electronic design systems is provided. The method includes extracting topological characteristics data corresponding to one or more polygons to form one or more virtual topological polygon. Each virtual polygon is represented by Scan order (SO), with SO corresponding to order in which the vertices of polygon are encountered by a sweep line moving in predefined direction with a predefined angular orientation. The method further includes determining dimensional data corresponding to each polygon to form one or more sized polygons using one or more virtual topological polygon. Thereafter, the spatial data corresponding to each sized polygon is extracted to instantiate each sized polygon.
