A method for generating a linear piecewise representation of a driver output current signal includes segmenting the driver output current signal such that an integral of each segment matches an actual voltage change in corresponding portion of an associated output voltage signal (within a desired tolerance). The beginning and ending current/time values for each segment can then be compiled into the piecewise linear representation of the driver output current signal. A method for generating a model driver output current signal includes conformally mapping first and second sets of precharacterization output current data based on a weighted average of the indexing parameter (e.g., input slew or output capacitance) values for the model driver output signal and the first and second sets of precharacterization data.
