Abstract
During the design process, simulation of automotive systems is often used. At this stage, electromechanical devices (solenoids, motors, sensors) are modeled at the behavioral level. Later in the verification phase, the electromagnetic behavior of these devices causes the actual system to operate outside the limits of its required specification. We demonstrate how simulation can be used not only during the design phase, but can also replace a major portion of the verification phase of the design cycle. The use of finite element (FE) analysis to solve the electromagnetic behavior of components is shown. The behavioral models are replaced by these FE based models in turn creating models which are then used in a complete system simulation. We illustrate this with an anti-lock brake system taking into consideration all of the major components using the VHDL-AMS modeling language.
