The code was developed and tested on a Xilinx Spartan-6 XC6SLX16 FPGA. It can be easily ported to any Xilinx Virtex-5, Virtex-6, Spartan-6 FPGAs and other FPGAs capable of running at 125 MHz. Please note that the target FPGA must be capable of creating a 2ns delay on the RGMII transmit and receive clocks. The Xilinx®LogiCORE™ IP Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media Independent Interface (RGMII) core provides the RGMII between RGMII Ethernet physical media devices (PHY) and the Gigabit Ethernet controller (GEM) in the Zynq®-7000 SoCs, Zynq®UltraScale+™ MP SoCs. In our hardware, we use Gem3 RGMII pins to connect to an ethernet switch directly. According to my undertanding, it should be called "fixed link". Then I refer to the links below: Zynq+Ultrascale+Fixed+Link+PS+Ethernet+Demo （This demo uses EMIO, so I only refer to the change for device tree.） Zynq...The user guide for the Gigabit Ethernet MAC v5.0 and v6.0 Core states that the RGMII interface is designed according to the RGMII v2.0 specification. The RGMII v2.0 specification indicates that HSTL should be used as the IOSTANDARD for the RGMII interface.

xilinx 7系列芯片不再支持LVDS33电平，在VCCO电压为3.3V的情况下无法使用LVDS25接口。 有些设计者想通过在软件中配置为LVDS25，实际供电3.3V来实现LVDS33也是无效的， D&R provides a directory of rgmii to gmii bridge. The Ethernet Media Access Controller (MAC) core can be configured to operate in either the Gigabit mode (1000 Mbits/sec data rate) or the Fast Ethernet mode (10/100 Mbits/sec data rate). 上图是am3358芯片的物理层接口，rgmii和mii，可以看出管脚数量不一样，以及clk的方向不一样，mii的rx和tx方向的时钟都是由phy或者fpga提供的，而rgmii则是谁发数据谁提供时钟，而且是双沿采样的。

Dec 08, 2015 · Tutorial Overview In this two-part tutorial, we’re going to create a multi-port Ethernet design in Vivado 2015.4 using both the GMII-to-RGMII and AXI Ethernet Subsystem IP cores. We’ll then test the design on hardware by running an echo server on lwIP. Our target hardware will be the ZedBoard armed with an Ethernet FMC, which adds 4 additional Gigabit Ethernet ports to our platform. Ports ...

今天讲解是rgmii的fpga设计。因为这边文章主要是用xilinx的约束工具，所以标记为xilinx，其实你用altera平台也可以的。设计分为2部分，一部分讲解mdio操作和iee802.3寄存器要求。 Looks like the only connection information I can find is the RGMII, but EMIO only accepts the GMII, so now we have rx0-7/tx0-7, etc. So, if we route to the Zynq out the EMIO, it goes to PL, and not possible to get back to PHY?
