Method and apparatus for evaluating effects of switching noise in digital and analog circuitry

摘要

The present invention is for a method and apparatus for analyzing the effect of a plurality of noise sources in a circuit, wherein each one of the noise sources is associated with a discrete stochastic process defined on a state-set of Markov chains. Each discrete stochastic process is modulated with a set of continuous signals that represents the noise generated by the corresponding noise source at each noise generating event. A spectral power density of the signals resulting from the modulation is computed and transferred through a linear system that represents a platform that supports the circuit. The output of the linear system comprises the spectral power density of interference signals at the points of interest and their correlations.
