VHDL implementation of CAN fieldbus modeling based on petri nets

This paper introduces a process for VHDL implementation of CAN field bus modeling based on Petri nets, which includes carrying on the model to DSPN (deterministic and stochastic Petri net) of the communication behavior of CAN field bus, combining Petri net with VHDL language, using Petri net to establish the model of CAN node hardware system, describing DSPN model of CAN node by VHDL language, simulating with the EDA software, obtaining the dynamic properties of the system, improving the analysis efficiency of CAN bus network performance. It is the basis of the communication protocol and circuit implementation.
