Abstract
A method and a system to pre-scan a file, analyze data and create the Condensed Macro Library (CML) file. The method used is to find macros or cells of certain classes that are defined by rules. After a suitable macro or cell is identified, a parser scans the macro or cell pins and finds pins which have ports with the shapes defined on the specific layers defined by the rules and user data. Further processing is then performed based on a set of rules and the pin data to generate a CML file that contains relevant information regarding relevant pins.
