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.
