Patent 7539961 was granted and assigned to Cadence Design Systems on May, 2009 by the United States Patent and Trademark Office.
A system and method for modeling an IC (integrated circuit) employs a mesh model and a grid model for separating impedance effects between nearby and far-away pairs of mesh elements. Models for relating currents and voltages can be incrementally adapted from other designs or design elements in applications including mixed-signal, analog and RF (radio frequency) circuits.
