鱼骨型时钟结构的快速实现方法

Fast Implementation of Fishbone Structure

针对CTS和传统鱼骨时钟结构(Fishbone)的优缺点,提出了一种结合两种方式优点的改进型鱼骨型时钟结构.针对传统鱼骨型时钟结构需要较多时间的缺点,提出了一种快速实现的方法.在相同的设计条件下,通过该实现方法与CTS和传统鱼骨型时钟结构加以比较,结果显示改进型鱼骨结构比CTS减少了50%左右的时钟延迟和20%时钟偏差;比传统鱼骨型时钟结构节省了60%以上的实现时间.

This paper provided a improved fishbone clock structure after compared the advantages and disadvantages of CTS and traditional fishbone. Besides that, this paper improved the fishbone＇s implementation methods. Under the same design condition, new methods fishhone has smaller skew and latency compared with CTS and much less implementation time compared with traditional fishbone.
