摘要
Abstract
With the development of Ethernet technology,the demand for data processing speed in the field of network data exchange is growing.Additionally,the reliability and autonomous controllability of the localized Ethernet interface are becoming increasingly impor-tant.In view of this,the QSGMII interface based on FPGA is designed using the top-down method,achieving the required transmission rate of 5 Gbps by the protocol.The design principle and idea of the key modules are described.A new multi-channel arbitration mecha-nism is proposed in the design,which improves the reuse of SGMII soft core and reduces the complexity of circuit design while ensuring the four-channel alignment.The software simulation of QSGMII interface verifies the correctness of RTL code function.Finally,based on VC709 FPGA development board,single channel data sending and receiving test was performed through network analysis software Wire-shark.Xilinx's QSGMII interface core was conneted with the self-developed QSGMII interface for data docking test,realizing the inter-weaving transmission of four independent SGMII interfaces.关键词
