摘要
给出了一种基于FPGA的高速LVDS接口设计,利用FPGA内部的SelectIO资源,设计并构造了LVDS接口发送单元、LVDS接口接收单元和对齐状态机。并基于Xilinx Virtex-5平台成功搭建了一个500 Mb/s高速LVDS串行互联系统,通过仿真和测试,验证了系统的有效性,为后续采用FPGA实现各种高速协议奠定了良好的基础。
This paper puts forward one high speed LVDS interface design method based on FPGA.Taking advantage of the SelectIO resource inside FPGA,this method designs the LVDS interface transmit unit,the LVDS interface reception unit and the alignment state.Based on Xilinx Virtex-5 platform,this paper successfully constructs one 500 Mb/s high speed serial interconnect system.This system passed simulation and test,and the efficiency of this method is verified.As a result,this paper is the stable basis of adopting FPGA to utilize the other high speed protocol.
