Multireflection algorithm for timed statistical coupled noise checking

An algorithm that completely characterizes the coupled noise for a pairwise coupled network with arbitrary lengths and reflection coefficients has been implemented in a coupled noise checking software. In this paper, an overview of the coupled noise methodology is briefly described so that the development of the reflection algorithm can be easily understood. Comparisons of the coupled noise predictor results to the ones obtained from detailed circuit simulation are presented. These results quantify the coupled noise predictor accuracy improvement when the timed noise reflections are included in the total coupled noise calculations and they demonstrate the computational time advantage that this approach has over device level simulations.
