Abstract
The present disclosure is directed to a method for extracting information for a circuit design. The method may utilize an incremental extraction process for extracting information for a portion of the circuit design. Extracted results of this portion may be merged with a previously extracted result to obtain an integrated result that is equivalent to that of extracting the entire circuit design. The incremental extraction process may identify a set of changed shapes, a set of affected shapes, and a set of involved shapes for extraction. The method may also divide the circuit design into a plurality of regions, wherein two or more regions may be processed in parallel.
