A model of a device is generated. An input port of the device is stimulated with a large amplitude signal having a central frequency. A first port of the device is perturbed with a small amplitude signal tone. The small amplitude signal tone is at a frequency offset slightly from a harmonic of the central frequency. Spectral component frequencies of a resulting signal from the device are obtained to determine model coefficients for the device. At least some of the spectral component frequencies occur at frequencies offset slightly from harmonics of the central frequency.

Behavioral model generation

The present invention includes a method for generating a model of a circuit having an input port and an output port. The method determines an amplitude for current leaving the output port at a frequency &#x3c9;when a signal that includes a carrier at &#x3c9;modulated by a signal V(t) is input to the input port, wherein &#x3c9;is a harmonic of &#x3c9;. The determined amplitude is used to determine values for a set of constants, a, such that a function f(V,a) provides an estimate of the current, I(t), leaving the output port at a frequency &#x3c9;when a signal having the form is input to the input port. Here V(t) is a component of a set of values V. The f(V,a) are used to provide a simulator component adapted for use in a circuit simulator.
