Patent 11276677 was granted and assigned to Cadence Design Systems on March, 2022 by the United States Patent and Trademark Office.
Disclosed is an approach to implement multi-die concurrent placement, routing, and/or optimization across multiple dies. This permits the multiple dies to be modeled as a single 3D space. Instead of being limited to a 2D plane, a cell can be placed to the area of any of the dies without splitting the netlist beforehand.
