通过分析CTS时钟树与鱼骨型时钟树的特点
基于传统鱼骨型时钟容易出现破坏原有设计的逻辑结构的情况
采取至少保留两级门控时钟的结构
在特定点作鱼骨型时钟网络
结合设计需求
使用两种不同的与CTS时钟树相结合的点接鱼骨型时钟网络设计方案.在相同条件下
发现点接鱼骨型时钟网络在时钟延迟上比CTS少了47%
而功耗也降了18%
功能验证方面较于传统鱼骨型时钟更为稳定.
On the analysis of characteristics of the CTS and fishbone
and based on the situation that traditional fishbone prone to destroy the logical structure of original design
thus reserve the structure of 2 levers ICGs at least
bulid fishbone at specific points in clock network.According to the design requirements
there are two different new means of fishbone clock network combination with CTS.Under the same conditions
the clock delay in fishbone built on clock network points is less 47% than CTS
power consumption also reduce by 16%
and function verification is more stable than traditional fishbone.
