添加ChipScope标志信号没有断言

亲爱的大家，
我在使用ChipScope进行调试时遇到了一个非常奇怪的问题。
我使用ML605板通过FMC HPC接口控制和与CMOS传感器通信。
我的设计被正确模拟，但我没有成功实现设计（标志信号没有断言）。
然后我添加了ChipScope进行调试，没有任何代码更改，我的设计已经成功实现。
所有信号都由ChipScope正确显示。
此外，在另一种设计中，除了添加ChipScope调试器之外，我无法从双端口RAM读出正确的数据。
这让我很困惑。
ChipScope会影响信号的时序还是优化信号的路径和位置？
我很感激任何帮助。
干杯

Dear all,

I met a very strange issue when I was debugging with ChipScope.

I used ML605 board to control and communicate with a CMOS sensor via FMC HPC interface. My design was correctly simulated, but I was not successful to implement the design (Flag signals did not assert). Then I added ChipScope to debug, without any changing of code, my design has been successfully implemented. And all the signals are correctly displayed by ChipScope.

Furthermore,  in an other design, I can not read out the correct data from a dual port ram only except adding a ChipScope debugger.

It really confuse me. Does ChipScope affect the timing of signals or it optimize signals' route and place?

I am grateful for any help.

Cheers
