为实现GRM与SVOM卫星平台的通信，以FPGA为核心， SJA1000为总线控制器，完成了CAN总线通信的设计与测试。 SJA1000控制器包括读写控制、地址通信、FIFO和时钟4个模块。其中优化了读写时序。仿真结果验证了设计的合理性，示波器采集信号和USB总线采集的数据，均表明CAN总线通信成功。

For the connection between GRM and platform onboard SVOM satellite , CAN bus communication based on FPGA and SJA 1000 has been designed and tested .The SJA1000 controller is composed of four mod-ules, which are read-write control, address communication , FIFO and clock.And the read-write timing has been optimized .Simulation of the SJA1000 controller is consistent with the design .The CAN bus communica-tion was finally verified by the signal acquired by oscilloscope and the information inspected by USB .
