Abstract
Any node, taking a part in a multiplexed car architecture can be modeled - with respect to the ISO/OSI reference model - by means of a layered structure. The building blocks of this structure are the Physical Layer, the Data Link Layer and the Transport or Network Layer, the Interaction Layer, the Network Management Layer and finally the Application Layer.
Computer-based models can be used at their best even with "lower" level layers of a CAN-based system like Physical Layer or Network Management Layer.
The paper will show the benefits that can derive from modeling and simulation with respect to the analysis of the Physical Layer and of the Network Management Layer.
Special focus will be put on the study of the High Speed CAN bus layout design and simulation on one side. The development of a Network Management Layer model will be described in the second part, demonstrating the benefits of such and approach to the validation and verification procedures both at component level and at system level.
