前言

前面我们基于GT 64B66B设计了自定义PHY层，并且也介绍过了基于AURORA8B18B IP核的使用，AURORA8B18B IP核的使用可以说是与AURORA8B18B IP核完全一致，可参考前文：https://blog.csdn.net/m0_56222647/article/details/137261729?spm=1001.2014.3001.5502

一、IP核配置

与8B10B大题是一样，接口也类似
在这里插入图片描述

二、设计框图

设计框图与8B10B一致，模块功能也是一样的，大部分模块都直接使用example design当中的即可，只有aurora_64b66b_0_CLOCK_MODULE模块进行了简单的修改，将INIT_CLK的双端转单端放到了顶层模块。
