IMPROVING ANALOG SIMULATION SPEED USING THE SELECTIVE MATRIX UPDATE APPROACH IN A VHDL-AMS SIMULATOR

KHER, SAMEER

Abstract Details

2005, MS, University of Cincinnati, Engineering : Computer Engineering.
Dynamic systems of nonlinear differential algebraic equations (DAE) are used to model a large class of engineering and biological systems. Simulation of a continuous-time system involves finding consistent solution over time of the DAE set that specifies the behavior. Hence, continuous-time simulators solve the DAE set at several time points. A wide variety of numerical algorithms are available to perform this repeated solution. One of the most robust methods that can be applied to a wide variety of systems is the Newton-Raphson method.The two most time consuming processes in the Newton-Raphson method for analysis of nonlinear DAE sets are found to be the Jacobian matrix formulation and the linear system solution. Methods are presented in this thesis to significantly reduce Jacobian matrix formulation times, and hence improve simulation speeds, by selective update of the Jacobian matrix.
