Abstract:
1. A method of determining noise propagation in an integrated circuit, comprising: receiving a characterization of a noise waveform incident on a cell of the integrated circuit, wherein said characterization comprises information on a shape of the incident noise waveform, wherein said shape of the incident noise waveform is characterized by an incident parameter set including an amplitude parameter and a plurality of shape parameters, reducing dimensionality of said incident parameter set; simulating response of said cell to the characterized noise waveform, wherein said simulating the response of said cell is performed using the reduced incident parameter set; determining a characterization of resultant noise output of said cell based upon said results of simulating; determining an output parameter set; and determining a correction parameter set that accounts for errors between the outputs obtained with reduced incident parameter set and the outputs obtained with incident parameter set.
