. Rather than approach the parallelization of the harmonic balance simulation method numerically, a novel schedulingoriented approach is described. The technique leverages circuit substructure to expose potential parallelism in the form of a directed, acyclic graph (dag) of computations. This dag is then allocated and scheduled using various linear clustering techniques. The result is a highly scalable and efficient approach to harmonic balance simulation. Two large examples, one from the integrated circuit regime and another from the communication regime, executed on three different parallel computers are used to demonstrate the efficacy of the approach. 1 Introduction The harmonic balance simulation method is widely used in the arena of largesignal, steadystate analysis of nonlinear circuits. It is often times applied to high frequency electronics since it directly accommodates frequency domain models [9, 10, 4]. Direct support for frequency domain models allow harmonic balance to...

LUNSFORD II, PHILIP J. The Frequency Domain Behavioral Modeling and Simulation of Nonlinear Analog Circuits and Systems. (Under the direction of Michael B. Steer.) A new technique for the frequencydomain behavioral modeling and simulation of nonautonomous nonlinear analog subsystems is presented. This technique extracts values of the Volterra nonlinear transfer functions and stores these values in binary files. Using these files, the modeled substem can be simulated for an arbitrary periodic input expressed as a finite sum of sines and cosines. Furthermore, the extraction can be based on any circuit simulator that is capable of steady state simulation. Thus a large system can be divided into smaller subsystems, each of which is characterized by circuit level simulations or lab measurements. The total system can then be simulated using the subsystem characterization stored as tables in binary files.
