ABSTRACT:
A method using a computer program for numerically simulating an electrical circuit, in a computer system, having a plurality of nodes and a plurality of circuit elements. A circuit description of the electrical circuit together with tstartand tstoptimes of a time interval are read into the computer system with at least one input value of the electrical circuit for at least one specific time in the time interval. Voltage values and/or current values at the nodes of the electrical circuit are calculated in the selected time interval using table-based models for the circuit elements. From these voltage values and/or current values, a simulation time tnin the time interval [tstart; tstop] under consideration is selected at which system equations are determined describing the circuit elements by physical formulas and dynamic effects of the elements are described by differential equations. The system equations are solved to calculate the voltage and/or current values at the nodes at the selected simulation time and a profile of previously calculated voltage and/or current values in the time interval are output from the computer system.
