This paper describes the use of behavioral models and mixed-signal simulation as a means to verify the proper instantiation, connectivity and control of analog and mixed-signal AMS intellectual property IP, and also as a means to prototype an AMS integrated circuit IC or system-on-chip SOC using behavioral models in place of IP modules yet to be designed. The goal of the first model use-case is to reduce the likelihood of human error resulting in IC functional faults. The goal of the second use-case is to develop an executable specification upon which the detailed design of IP blocks may be based.
