三.pl_eth_1g
四.github的开源代码
一.ps_mio_eth_1g
使用FPGA板载的RJ45接口，使用zynq Ultrascale+ Mpsoc的GEM3，然后直接用vitis或者SDK跑Iwip来构建以太网。
二.ps_emio_eth_1g
使用emio将GEM0引出，再配合1G/2.5G Ethernet PCS/PMA or SGMII核搭建，参考ZYNQ使用1G/2.5G Ethernet PCS/PMA or SGMII拓展PS端网口
之后在petalinux或者vitis中来开发。
三.pl_eth_1g
参考官方的zcu102例子搭建，使用SFP构建1000Base-x的转接口。
需要找到GTH(GTH是一种高速的收发器，支持500Mb/s到16.375Gb/s的传输速度)的位置。
如图所示，SFP_SI5328_OUT为BANK 225，pin为W10，X0Y10（SFP0）,需要修改为125MHz。

四.github的开源代码
直接在linux下make好zcu106对应的设计，然后ping对应的IP，这里使用的也是SFP，实现了一个回传发送。
