Abstract
A method for simulating an electric circuit comprising components and receiving external stimuli, wherein the determination at a given time of the voltages at the circuit nodes comprises several iterations, each consisting of defining a probable voltage for each node, of calculating the currents of each component based on the component model, then of repeating until the mesh equation is verified, and wherein for the first time, a current of a component is calculated based either on the full accurate model, or on the simplified linear model, or on the compound model which is a fitting, according to the interval between the voltages at the component's terminals between the initial time and the first time, and the simplified, full or compound model is used respectively if the interval is smaller than a first threshold, greater than a second threshold or between the first and second thresholds.
