ALINX以太网例程调试总结

RTL级别的MAC,支持千兆和百兆（10M测下来好像有问题），实现了基本ARP/ICMP/UDP功能。不得不说这个很厉害了，对以太网的协议需要非常了解。

但我在将代码移植到其它平台时，实际测时发现了一些问题。

按照RGMII来说：时钟设计：

由于RGMII接口存在两种时序，一种中心对齐一种边沿对齐。

这个设计是按中心对齐直接做的：

输入时钟通过BUFG直接去拍RXD数据，数据通过IDDR进入，时钟路径如下：

输出时钟直接拍TXD,通过ODDR:

1、缺少io延时约束文件

参照xilinx的约束文件【GMII to RGMII v4.0/pg160】：接收约束和发送越是应该都是两种参数，但实际却只有发送有两种，这一点我很奇怪。而且输入约束也和自己计算的结果对不上。。。
