Multi-reflection algorithm for timed statistical coupled noise checking

An algorithm has been formulated to predict the composite coupled noise signature at the receiver input for impedance mismatches associated with the package/chip interface. The formulation results in an efficient vectorized format for the reflected waves such that execution time is reduced while noise prediction approaches circuit simulation accuracy. A test case is presented to show the improvement in accuracy by accounting for reflections, when compared to circuit simulation as a benchmark. A brief discussion of execution time is also included.
