基于Verilog+HDL设计CAN控制器,详细介绍各功能模块的设计。本论文的重点是CAN总线通信控制器的前端设计。即用Verilog HDL语言完成CAN协议的数据链路层的RTL级设计，实现其功能，并且能够在FPGA开发平台Quartos上通过仿真验证，证明其正确性-Verilog+ HDL-based design of CAN controller, detailed design of each functional module. This paper focuses on the CAN bus communication controller front-end design. Verilog HDL language that is used to complete the data link layer CAN protocol the RTL-level design, to achieve its function, and can be on the FPGA development platform Quartos by simulation to prove its correctness
