Table-driven circuit elements in spice-like simulation programs

Abstract

Table-driven approximation of semiconductor device characteristics and table-driven behavioral descriptions are two particularly attractive examples of enhance- ments that can significantly speed up circuit simula- tion by eliminating many time-consuming calculations in which device voltages and currents are derived from properties and geometries of semiconductor materials. Several extensions to a SPICE-compatible simulation tool are described, that provide table-driven capabili- ties for all nonlinear SPICE circuit elements.
