Ken的博客系列之七 | 千兆位串行链路接口的SI方法

By Sigrity | 19 Sep 2019

作者：Ken Willis 上一篇：使用IBIS-AMI模型进行仿真反向信道训练均衡器自适应的另一项能力是反馈训练。许多高速串行协议规定SerDes接收器可以评估发射器送出的training patterns的信号质量，以此来决定发射器均衡的大小，然后将这个要求反馈给发射器，然后评估下一个training pattern。这个过程会重复多次，直到接收器对发射器的设置满意，那么这个满意的设置就会被实际传输出去。图1：反向信道训练（点击查看大图）尽管目前的IBIS标准还不支持反馈训练功能，...
