The detailed FPGA connections for the feature described in this section aredocumented in the SP701 board XDC file, referenced in Appendix B: Xilinx Design Constraints.10/100/1000 Mb/s Tri-speed Ethernet PHY (RGMII)[Figure 2, callouts 8, 9]A BECKHOFF IP ET1815, ET1816 MAC can be used to implement a 10/100/1000 Mb/sEthernet interface (supports EtherCAT for Industrial Ethernet applications) in Spartan-7 FPGA,shown in the figure below, that connects to an external TI DP83867IRPAP Ethernet RGMII PHYbefore being routed to an RJ45 Ethernet connector. The associated EEPROM has 12-bytereserved for the board serial number on start location of 0x14 and 6-byte reserved for theEthernet MAC ID on start location of 0x35.Chapter 3: Board Component DescriptionsUG1319 (v1.0) July 12, 2019 www.xilinx.comSP701 Board User Guide 23Send Feedback
