Simulation method and system for analyzing the stability of a modeled electronic circuit. Simulation of the transient response to a desired input stimulus is performed in a piece-wise fashion, in a sequence of transient time points. At one or more user-specified time points (“tpunch” points) within the transient interval, the state of the circuit in the transient response at that time point is applied to the model as if it were a DC operating point, and the small-signal stability of the circuit under those conditions is analyzed. Transient instability of the circuit is thus discovered by way of simulation, allowing the designer to determine the cause and cure of that instability.
