Abstract

A method of analyzing I/O cell layouts for integrated circuits, such as ASICs, includes defining a proposed I/O cell layout on a selected chip image, providing a set of limit rules for electromigration, IR voltage drop and di/dt noise for the selected chip image, providing characteristics for each I/O cell type used in the proposed I/O cell layout, checking the proposed I/O cell layout by applying the limit rules to the proposed I/O cell layout and reporting all I/O cells used in the proposed I/O cell layout that do not meet the limit rules for the selected chip image.
