Math-Based Computer-Aided Prototyping for Automotive Mechatronic Applications

Math-based Computer-Aided Prototyping (CAP) is a new and highly effective design methodology. Using math-based CAP, engineers create realistic “virtual” prototypes for a wide range of circuits and dynamic systems. The purpose is to gain understanding and ultimately improve their designs, as well as to share information and coordinate design knowledge.

VHDL-AMS (IEEE Std. 1076.1) is the technology standard that makes math-based CAP possible. VHDL-AMS is a versatile Hardware Description Language that is capable of describing analog and digital electronics, as well as non-electrical components with equal fidelity and accuracy. This makes it well suited for virtual prototyping of advanced automotive mechatronic systems.

This paper illustrates math-based CAP methods and key VHDL-AMS modeling capabilities through several examples. These methods are applicable for the design of various types of automotive systems including Electrical, Powertrain, and Vehicle Control.
