ABSTRACT

Charge oriented integration is necessary in general purpose circuit simulation for maintaining charge conservation. Generally, an approach derived by Ward and Dutton is implemented. Its drawbacks are higher expense for timestep control, loss of one integration order, and the fact that the user has no direct control of the variables which he really is interested in.An error estimate is proposed which is closely related to error estimates given by Gear, Leimkuhler et al. for differential algebraic equations of index 2. A timestep control algorithm based on this estimate requires extra solutions of a linear system with the matrix of the Newton procedure. First results indicate that this additional overhead is compensated by a better adaption of the timesteps. More... »
