Abstract

Recent applications of SPICE-PAC to transistor parameter extraction and hierarchical simulation require rather flexible circuit analyses, performed for irregularly distributed values of independent variables. An implementation of table-driven analyses (DC, AC, and time-domain) is described in which tables of arbitrarily distributed independent variables (voltages, frequencies, or timepoints) are used rather than the fixed-step strategy implemented in SPICE-like simulators. Simple examples are used to illustrate applications of table-driven analyses. The simple example of MOS inverter modeling shows that data-driven elements can provide the accuracy needed in practical applications, while reducing significantly the computational effort required for evaluation of complex models of semiconductor devices
