Abstract
Introduces a methodology for the evaluation of the interference noise caused by digital switching activity in sensitive circuits of a mixed digital-analog chip. The digital switching activity is modeled stochastically as functions defined on Markov chains. The actual interference signal is obtained through the modulation of this discrete stochastic signal with real current injection patterns stored a priori in a pre-characterized library. The interference noise results from the propagation of these continuous stochastic signals through the linear network that models the chip power grid, substrate and relevant package parasitics. The interference noise power spectral density is computed by linear frequency-domain analysis. The methodology is implemented using advanced numerical techniques that are capable of tackling very large problems.
