Abstract
The types and formats of frame and the bus control states, specified in CAN 2.0 bus protocol, are complex. For the realization of its protocol function and state control,in the actual circuit design process,use state machine to simplify and achieve the process of the status control and protocol function in CAN bus controller system. In this paper,based on this method,design the status control state machine and packet receiver state machine of CAN bus controller,build the hardware circuit by RTL code. Through the software platform of E language based Specman Elite and modelsim 6. 2 for simulation and verification, the circuit function is correct and meet the requirements of design and application.关键词
