ISE中chipscope的warings如何解决

警告：PhysDesignRules:367 - The signal
   <U_ila_pro_0/U0/I_NO_D.U_ILA/U_STAT/iSTAT<11>_wg_lut<7>> is incomplete. The
   signal does not drive any load pins in the design.如何解决，最好有详细过程，谢了搞了好久，实在是么得办法了

好像有一个“keep”属性，你可以百度查一下。

(*KEEP="TRUE"*)在前面加上，你先试试。

哪边的keep属性呀，求细节，本人比较菜

这个信号已经不存在了，把它去掉不就行了，你非要看它?

The syntax of the keep shows below.
For example:
if you want to keep the signal_a and the synthesis does not to optimize the signal_a.
(* keep = "TRUE" *)  wire signal_a;

    iSTAT<11>_wg_lut<7>这个chipscope要查看的信号已经不存在了，也或许是这一次综合后信号名和上一次不一致了。所以，请重新打开chipscope，删除掉这一条signal，然后另选一个正确的signal。

Ok, very good.
