Abstract :
An intuitive relationship between numerical integration algorithms and AWE is established. A small number of data points generated during a brief fixed timestep numerical integration of linear(ized) circuits are used to form sampled waveform integration, correction and extrapolation (SWICE) models. This method preserves the efficiency of the AWE technique, while increasing the accuracy and generality. The strengths of such an approach are illustrated from a theoretical view, as well as with practical examples.<>
