Abstract
The present invention includes a system for and a method of determining noise characteristics of a circuit of an integrated circuit. The circuit is classified based on its topology and measured circuit parameters. Noise characteristics are retrieved using the circuit classification and circuit parameters to calculate a noise response. Classification and characterization may be performed on each individual input.
