嗨,
我们在这里有一个Spartan6设备,想知道我们是否可以在DCM保持复位期间使用DCM的状态输出。
在启动时,我们希望将DCM保持在重置状态。
顺便说一句,我必须说保持DCM的逻辑在另一个时钟域。
我们希望捕获(同步)状态位(输入时钟切换)并决定释放DCM重置。
现在,我不确定我们是否将DCM保持在复位状态,它会在此期间断言/取消断言其状态输出。
有人可以澄清一下吗?
非常感谢!

Hi,
We have one Spartan6 device here and want to know if we can use the status outputs of DCM during the DCM is hold in reset.
At startup we want to hold the DCM in reset. Btw, I must say that the logic that holds the DCM is in another clock domain.
We want to capture(synchronize it) the status bit(input clock is toggling) and decide to release the DCM reset.
Now, I'm not sure if we keep DCM in reset will it assert/deassert its Status Outputs or not during this
time.
Can someone clarify this?
Many Thanks!
