【Verilog基础】关于Clock信号的一些概念总结(clock setup/hold、clock tree、clock skew、clock latency、clock transition..)
2022-06-30 15:44:00 【ReCclay】
setup time:触发器(DFF)时钟上升沿到来之前,数据需要保持稳定的最小时间间隙就是建立时间。
hold time:触发器(DFF)时钟上升沿到来之后,数据需要保持稳定的最小时间间隙就是保持时间。
clock skew:由于路径延迟,同一个时钟信号到达两个不同的寄存器之间的时间差值,根据差值可以分为正偏移和负偏移。
时钟树到达不同终点的时间差。

clock jitter:指的是时钟周期的变化。指两个时钟周期之间存在的差值,这个误差是在时
