TECHNICAL SESSION Modern automotive systems are a sophisticated blend of electronics, sensors, and actuators -- a blend that challenges even the most capable design team. It is no secret that modeling and simulation, though once an option, is now required in every system design flow. In the modeling and simulation process, device modeling is often the bottleneck. While vendor-supplied models for many electronic components are readily available on the Internet, the same cannot be said for non-electronic devices. Go beyond the semiconductor segment in your model search, and the number of vendor models drops significantly. Without a vendor-supplied model, design teams frequently use complex modeling languages to create their own device models. There is, however, an alternate, graphics-based modeling method that is very intuitive, applies across technologies and levels of model abstraction, and leads to accurate device models in a fraction of the time needed to develop a language-based model. This session introduces this graphics-based modeling methodology and illustrates the technique with several examples created in the SystemVision modeling and simulation environment.
