Using SystemC AMS for heterogeneous systems modelling at TIER-1 level

For the design of cyber-physical systems in the automotive domain we have to take more and more the complete value chain from the semiconductor (TIER-2) via the component (TIER-1) up to the automobile manufacturer (OEM) into account. The current requirements for safety, comfort and energy efficiency, and, above all, the rising cost pressure calls for system designs covering different domains (e.g., mechanics, analogue, and digital electronics) as well as software being tightly coupled. Due to this increasing complexity there is an indispensable need for virtual prototypes. However, the creation of such TIER-1 designs bares some challenges, for example simulation performance, modelling effort, and the assembly of models from different vendors. This paper discusses various ways for creating models for a system simulation at TIER-1 level, such as the anti-lock braking system. It is shown, how to combine these methodologies and how to integrate them into a typical TIER-1 design environment.
