Abstract
A method, system and apparatus is provided to perform noise analysis of electrical circuits. The method and system partitions an original multi-port circuit to a reduced circuit model having a specific layout configuration. The reduced circuit model may have a variety of configurations. Then an input signal is applied to a first port of the reduced circuit model using the specific layout configuration and an output signal is measured from a second port of the reduced circuit model. The process continues until all input ports which may contribute noise to the circuit are measured and then the results are calculated to determine the total output of simulated noise experienced by the circuit. The calculated output results of the reduced circuit model are then used to determine whether the original circuit is designed to withstand the quantity of noise experienced by the reduced circuit model.
