Patent 7171346 was granted and assigned to Freescale Semiconductor on January, 2007 by the United States Patent and Trademark Office.
A mismatch modeling tool (10) comprises a software implemented mismatch model (32). The software implemented mismatch model (32) accesses: at least one editable mismatch model data library (18) comprising process parameter variables, and circuit simulation library and program (14) data output. An interface screen (100) provides input and output coupling between a user and the software implemented mismatch model (32).
