Abstract
Techniques for analyzing a routed interconnection of a net of a circuit are discussed herein. Some embodiments may include a method comprising with a computer, analyzing the circuit to determine a performance parameter of the net, wherein the circuit is analyzed based at least in part on applying pre-layout simulation data of the net to layout data of the circuit. Additionally or alternatively, the circuit may be analyzed based on extracting characteristics of the routed interconnection from the layout data of the net.
