Design of 16-channel Ethernet Tester

摘要: 针对传统的以太网测试采用ping包方式存在带宽窄、操作不方便等问题，提出了一种基于C8051单片机和FPGA模块的16路以太网测试仪的设计方案。该测试仪支持16路以太网测试，其中的FPGA模块可提供对外的16路SMII，发送方向用于接收C8051单片机的配置数据并根据配置数据发送相应的以太网包，接收方向用于检测和统计接收到的以太网包，并把统计信息回传给C8051单片机。测试结果验证了该测试仪的可行性。

Abstract: In view of problems of narrow band width and inconvenient operation in traditional Ethernet tester by use of ping packet method, the paper proposed a design scheme of 16-channel Ethernet tester based on C8051 single-chip microcomputer and FPGA module. The tester supports 16-channel Ethernet test, and its FPGA module can provide 16-channel external SMII, whose sending unit is used to receive configuration data of C8051 single-chip microcomputer and send corresponding Ethernet packet according to the configuration data, and receiving unit is used to detect and statistic received Ethernet packet and send the statistical information to C8051 single-chip microcomputer. The test result validated feasibility of the tester.
