Session 22 - Noise and oscillator simulation

Although many circuits can be efficiently analyzed by the general algorithms available in SPICE-like circuit simulators, there are certain classes of problems where brute-force simulation is not useful. One such problem is analyzing the effect of noise on switching circuits, where the probability of encountering an issue is so low that the simulation times needed to catch problems is prohibitively large. A second is for oscillator analysis, where conventional time-domain methods must simulate for a very large number of oscillation periods to capture details of slower superimposed variations or of noise. For these classes of problems domain-specific analysis algorithms have been developed that enable efficient modeling and simulation of the narrow problem of interest. Historically many of these developments have been reported at CICC, and this session continues that tradition.
