摘　　要：介绍了USB协议芯片FT245RL的工作原理,设计了FT245RL与FPGA的接口电路,给出了FPGA发送和接收数据帧状态机的VHDL语言的描述,并调试其与上位机的通信;简化了电路设计,提高了测试效率,该设计具有很强的通用性,该电路已成功地应用到航天某型号的测试设备中。This paper has described the operation principle of the FT245RL which is an USB protocol chip, designed the interface circuit between FT245RL and FPGA, showed the description of the FPGA to send and receive data frames used VHDL language. And debuged the communication between FPGA and the host computer. It has facilitated the circuit design and improved the test efficiency, the design has a strong all--purpose commonality, the design has been successfully applied to some space test devices.
