Warning: Found pins functioning as undefined clocks and/or memory enables
Info: Assuming node "CLK" is an undefined clock
Info: Assuming node "stop" is an undefined clock
Info: Assuming node "WR" is an undefined clock
Info: Assuming node "actsig" is an undefined clock
Warning: Found 3 node(s) in clock paths which may be acting as ripple and/or gated clocks -- node(s) analyzed as buffer(s) resulting in clock skew
Info: Detected ripple clock "standconuter:inst|composite:inst|sp" as buffer
Info: Detected gated clock "standconuter:inst|inst4" as buffer
Info: Detected ripple clock "standconuter:inst|count8l:inst1|temp[7]" as buffer
其中clk,stop,wr,sp,temp是我内部定义的几个接口或变量
请帮我看看这个报警是什么意思?应该怎么解决?
警报:找到没定义的时间和/或存贮器使能管脚功能。
信息:assuming 节点CLK 是没定义的时钟
信息:assuming 节点STOP是没定义的时钟
信息:assuming 节点WR 是没定义的时钟
信息:assuming 节点actsig是没定义的时钟
-----但是我这些信号或管脚我全是定义了的啊-------
警报:找到在时钟路径里3个节点可能ripple或/和时钟门,分析的结果是时钟偏斜。
信息:探测到ripple时钟sp 为缓冲器
信息:探测到 门 时钟inst4为缓冲器
信息:探测到ripple时钟temp[7]为缓冲器
------这个警告是不是说我的这几位信号时间延时太厉害了?------ |
