“…Because of the broadcast nature of the CAN [5] protocol (i.e. messages are not sent to a specific destination address, but rather as a broadcast), the chosen crossbar switch is configured by closing all its crosspoints to ensure that the CAN message will be sent at the same time [6,7] for all outputs nodes as it is defmed in CAN protocol [8]. CAN messages need to be queued in buffers when short-term overloading occurs, where the sum of input rates for a single output port exceeds the outgoing link rate (see figure I).…”

Nowadays, CAN bus, as a well-known, field bus, reaches its limits when dealing with sophisticated embedded systems that require reliability and high-speed data transfer. Switched fabric can be a fast and reliable hardware solution for existing CAN-bus limits. In fact, it allows multiple packets to be transferred simultaneously ensuring sufficient bandwidth. To resolve this problem when keeping the use of CAN protocol, we remove the CAN access technique module from an existing VHDL implementation of a CAN controller component and we replace it by a crossbar switched fabric, implemented in VHDL also. In this paper, we designed a Crossbar switched fabric CAN based on VHDL modules and we simulated it under ModelSim tools and we give of proof-of-concept of a CAN controller based on crossbar switched fabric.

The rising demands for safety, power-weight reduction, and comfort make the in-vehicle network of embedded electronic systems very complex. In particular system reliability is essential, especially because of the safety requirements. Test and verification of the entire in-vehicle network by means of behavioral simulations are each time more widely adopted. To this aim, behavioral models that faithfully represent the behavior of mixed-mode-embedded systems are essential for achieving reliable simulation results. This paper presents a systematic development methodology for mixed-mode behavioral models of in-vehicle-embedded systems. The methodology allows achieving accurate models, which provide reliable system simulations. The model development methodology is described and the results of the methodology applied to two case studies are presented: (1) the mixed-mode behavioral model of a generic Flexray physical layer transceiver and (2) the mixed-mode behavioral model of a CAN bus transceiver-integrated circuit. The simulation results show that behavioral simulations are much faster than transistor level simulations. Moreover, behavioral simulations are flexible, which allows quickly changing and verifying the communication network topology if compared with hardware prototypes.
