非常感谢你的帮助。
我之前已经阅读过该消息，但是我的整个总线引脚都已解锁，我确信总线上的所有引脚都是用ucf文件写的，如下所示：
NET ADC2_ChA_D_P [0] LOC = B32;
#ADC2通道ANET ADC2_ChA_D_N [0] LOC = A33;
NET ADC2_ChA_D_P [1] LOC = E32;
NET ADC2_ChA_D_N [1] LOC = E33;
NET ADC2_ChA_D_P [2] LOC = B33;
NET ADC2_ChA_D_N [2] LOC = C33;
NET ADC2_ChA_D_P [3] LOC = F33;
NET ADC2_ChA_D_N [3] LOC = E34;
NET ADC2_ChA_D_P [4] LOC = C32;
NET ADC2_ChA_D_N [4] LOC = D32;
NET ADC2_ChA_D_P [5] LOC = G32;
NET ADC2_ChA_D_N [5] LOC = H32;
NET ADC2_ChA_D_P [6] LOC = C34;
NET ADC2_ChA_D_N [6] LOC = D34; NET ADC2_ChB_D_P [0] LOC = L33;
#ADC2通道BNET ADC2_ChB_D_N [0] LOC = M32;
NET ADC2_ChB_D_P [1] LOC = L34;
NET ADC2_ChB_D_N [1] LOC = K34;
NET ADC2_ChB_D_P [2] LOC = P32; NET ADC2_ChB_D_N [2] LOC = N32;
NET ADC2_ChB_D_P [3] LOC = P34; NET ADC2_ChB_D_N [3] LOC = N34;
NET ADC2_ChB_D_P [4] LOC = R33; NET ADC2_ChB_D_N [4] LOC = R32;
NET ADC2_ChB_D_P [5] LOC = U32;
NET ADC2_ChB_D_N [5] LOC = U31;
NET ADC2_ChB_D_P [6] LOC = U33;
NET ADC2_ChB_D_N [6] LOC = T34;
我真的不知道这个警告是怎么出来的。

Thank U so much for your help.
I've read that message before, however my entire bus pins are all unlocked, and I'm sure all my pins in bus are written in ucf file as following :

NET  ADC2_ChA_D_N[0]   LOC =A33;
NET  ADC2_ChA_D_P[1]   LOC =E32;

I really do not know how this warning is coming out.

这是一种脑死亡的方法，但它可能会起作用......
尝试重命名.UCF文件，以便ISE忽略它。
更改文件名后缀。
重新编译，并查看是否仍然弹出错误消息。
如果仍然弹出错误消息，则项目搜索路径中的另一个.UCF文件会潜入您的编译中。
也许'项目清理'会有所帮助。
如果错误消息未弹出，则问题出在原始.UCF文件中。
分裂和征服的时间。
如果您不知道.UCF文件中的哪个位置可能存在问题，那么划分和征服技术的工作原理如下：
注释掉整个.UCF文件。
重新编译。
错误信息？
如果不是，请取消注释.UCF文件的一小部分并重新编译，直到找到“冒烟”。

以下为原文

This is a brain-dead approach, but it might work...
 

• Try renaming your .UCF file so that ISE will ignore it.  Change the filename suffix.  Recompile, and see if the error message still pops up.
  

• If the error message still pops up, you have another .UCF file in your project search path which is sneaking into your compiles.  Maybe 'project cleanup' will help.
  

• If the error message does NOT pop up, then the problem is in your original .UCF file.  Time for divide and conquer.
  

If you don't know where in your .UCF file might lay the problem, divide and conquer technique works like this:
 

• Comment out the entire .UCF file.
  
• Recompile.
  
• Error message?
  
• If no, un-comment some small section of your .UCF file and re-compile until you find the 'smoking gun'.

Summary:
1. Read the manual or user guide.  Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts.  If I write a good post, then I have been good for nothing.

非常感谢你的回复，我已经一步一步地尝试了你的建议，尽管仍然会出现警告。
当我重命名ucf文件时，会弹出错误以查找缺少的约束：
错误MapLib：717  - 设计使用2个IDELAYCTRL，其中2个没有定义LOC属性。只有一个IDELAYCTRL原语没有LOC属性。
这意味着我对ADC模块引脚的限制是否正常？
这里IDELAYCTRL是ADC模块顶层的基元。
我试图用verilog编写相同的东西，结果证明它运行良好。
我无法弄清楚问题出在哪里。
顺便说一下，我很抱歉两次发布相同的主题，事实上，那是因为我的网络有一些问题，我只是F5两次，但是当我意识到这一点时，我不知道如何删除我的
线程，也许你可以帮助我。
期待您的进一步帮助〜非常感谢U~

Thank you so much for your sinsere reply, I've tried your suggestions step by step, though the warnnings still pop up.
When I rename the ucf file, the errors are pop up for missing constraints :
ERROR MapLib:717 - The design uses 2 IDELAYCTRLs and 2 of them do not have LOC property defined.There can be only one IDELAYCTRL primitive with out LOC property.
that means my constraints for my ADC module pins are OK?
Here IDELAYCTRLs are primitives in ADC module top level.
 
I've tried to write the same thing all in verilog, and it turns out to be working well. I cannot really figured out  where the problem is.
By the way, I'm sorry for posting the same topic twice, in fact, that is because there is some thing wrong with my network, and I just F5 twice, however when I realize this, I do not know how to delete my thread, maybe you can help me.
Looking forward for your further help~ Thank U so much~
