Efficient system for multi-level shape interactions

摘要

A structure and method for evaluating an integrated circuit design includes adding a superseding layer of the integrated circuit design over a previous layer of the integrated circuit structure, identifying database pointers for regions and edges within the superseding layer and the previous layer, removing database pointers for regions of the previous layer overlapped by the superseding layer, classifying the superseding layer and the previous layer as the previous layer, and repeating the method until all layers of the integrated circuit are evaluated.
