Fast evaluation of digital switching noise for synthesis of mixed-signal applications

This paper presents a novel symbolic analysis method for transient analysis of digital switching noise (DSN). The method relies on symbolic techniques to express the voltage variations at the power pins of analog blocks depending on the DSN at the switching digital blocks. The paper discusses the modeling of DSN propagation including the representation of the substrate coupling, contacts to the power supplies and power buses. Experiments support the correctness of the method and showed significant speed-ups of simulation time as related to SPICE simulation.
