摘要:

描述由Casper等人提出的峰值畸变算法,精确计算了高速片上系统最坏情况下的眼图,以及此时的输入码型。针对少量伪随机码在反应高速片上系统最坏情况性能精确度上的缺陷以及大量随机码型仿真时间长的问题,文中将峰值畸变算法应用于DDR3的CMD情况,说明了算法在解决这两个问题上的优势。

关键词: 峰值畸变算法, 最坏情况, 最坏码型, 眼图

Abstract:

The Peak Distortion Analysis(PDA) algorithm proposed by Casper is presented in this paper which accurately calculates the worst-case eye diagram and input bitpatterns for chip-to-chip signaling systems.In order to solve the problems that the worst-case eye diagram for many high-speed chip-to-chip communication systems can not accurately characterized by a small set of random input data,and that the simulation time of a very large set of random data is prohibitive,the algorithm is applied to the CMD condition of DDR3.Application shows the superiority of PDA algorithm in the solution of the two problems.

Key words: peak distortion analysis algorithm;worst-case;worst-case data pattern;eye diagram
