摘要
Casper提出的PDA算法,引入了一个精确的对高速芯片间信令系统建模方法,文中针对眼图仿真伪随机码流较长的问题,利用该算法对系统进行建模,快速计算出最坏情况下位流模式和眼图轮廓,实现了DQ数据的最坏眼图和最坏位流模式。
PDA algorithm proposed by Casper introduces an accurate method of modeling the performance of high-speed chip-to-chip signaling systems. In this paper, in order to solve the problem of eye diagram simulation with long pseudo-random bit stream, this algorithm is used to model the system and calculate worst-case bit patterns and eye diagram quickly, thus realizing the worst-case bit patterns and eye diagram of DQ data.
