Behavioral modeling refers to the substitution of more abstract, less computationally intensive circuit models for lower level descriptions of analog functions. These simpler models emulate the transfer characteristics of the circuit elements that they replace, but with increased efficiency, leading to substantial reduction in the actual simulation time per circuit. This reduction in elapsed time per simulation, when considering the whole of the design and simulation cycle, can lead to a tremendous increase in design efficiency, as well as possible reduction in the time necessary to take a design from a concept to a marketable product.
This chapter describes how to create behavioral models in the following topics:
