Antenna effect prevention by model extraction in a circuit design for advanced processes

摘要

A method is disclosed for determining an antenna ratio for an interconnect in a circuit. The interconnect may be routed through one or more connection layers and may be electrically coupled to one or more gate oxide areas. A cumulative antenna ratio for all components on each connection layer is determined by considering an antenna effect caused by each component on a predetermined connection layer with regard to the gate oxide areas coupled thereto and any components on one or more connection layers coupled between the component of the present connection layer and the gate oxide areas. In the same fashion, a top layer cumulative antenna ratio for the interconnect is determined based on the cumulative antenna ratios for the connection layers below the top layer.
