Full system verification of CAN network at high speed transmission rate using VHDL-AMS

This paper considers the full system verification of a large size CAN network (up to 24 nodes) at high transmission rate (500 Kbps and 1.0 Mbps). The entire CAN physical layer is simulated by using behavior modeling language (VHDL-AMS) in comparison to measurement. The modeling of measurement environment of the CAN network is discussed, showing how to get the measurement and simulation results well matched. This demonstrates that the simulation solution is reliable, which is highly desired and very important for the verification requirement in CAN physical layer design. With the developed CAN measurement system, application layer is also proven working properly when implementing different non-standard topologies at high speed transmission rate.
