Development and verification of in-vehicle networks include multiple design layers. These layers include the logical layer represented by the software application, the associated data link layer, and the physical connection layer containing bus interfaces, wires, and termination. Verification of these systems in the early stages of the design process (before a physical network is available for testing) has become a critical need. As a result, the need to simulate these designs at all their levels of complexity has become critically important. In-vehicle networks can be simulated on many different abstraction levels using various model levels and modeling technologies. Early in the development process, analyses can be performed without having available any detailed models from the chip manufacturer or component supplier. Later in the development process, more accurate models can be integrated into the simulation process, including those provided by suppliers and chip manufacturers. This paper demonstrates a portion of the development and verification process of the physical layer of an in-vehicle CAN Bus at Volkswagen using the Saber simulation environment. This paper also demonstrates integrating portions of the logical layer into the simulation so both logical and physical layers can be simulated together.
