Abstract:
1. A method for using a computer system to numerically simulate an electrical circuit having a plurality of nodes and i circuit elements, the method which comprises: a) reading a circuit description of the electrical circuit into the Computer system; b) reading in times t c) reading in at least one input value of a voltage and current for the electrical circuit for at least one specific time in the time interval [t d) calculating voltage values and/or current values at nodes of the electrical circuit at a plurality of times in the time interval [t e) selecting a simulation time t f) determining system equations of the circuit description for the simulation time t g) calculating the voltage values and/or the current values at said nodes of said electrical circuit at the simulation time t h) using an equation t and h i is a maximum permitted increment of an i-th one of the circuit elements; i) repeating steps f) to h) for a simulation time t j) outputting, on an output unit of the computer system, a profile of the voltage values and/or the current values that were calculated in step g) in the time interval [t
