ABSTRACT:
A method and apparatus for simulating the design of an integrated circuit uses a processor (200). The processor (200) executes a simulator (540) from memory (280) to exercise a model (544). The data points (15-27) of an output signal are stored in a history data file (542). The techniques used to generate each of the data points (15-27) are also stored in the history data in file (542). The history data are then used to generate a converted output signal that has a uniform time scale. If the converted output signal requires the generation of a desired data point, then the approximation technique used to generate the following data point stored in the history data (542) is used.
