Systems and Methods for Designing and Making Integrated Circuits with Consideration of Wiring Demand Ratio

Synopsys, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 3 of these applications claim priority to application 61/287,344, filed Dec 17, 2009. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
