WARNING: Par:288 -IBUF has no load

Hi, My current work is targetting Virterx-4.

The Place&Route step was performed after assigning each in-output pin.  

However, I got the following  messages

 


WARNING:Par:288 - The signal ea_in_IBUF has no load.  PAR will not attempt to route this signal.
WARNING:Par:288 - The signal wbi_dat_i<20>_IBUF has no load.  PAR will not attempt to route this signal.
WARNING:Par:288 - The signal wbi_dat_i<21>_IBUF has no load.  PAR will not attempt to route this signal.
WARNING:Par:288 - The signal wbi_dat_i<22>_IBUF has no load.  PAR will not attempt to route this signal.

I can't find the reason of this problem, and the interesting  thing is that "wbi_dat_i" is declared as 32 bits in my work. 

However, this problem is occuring only on the 16~31th bits!

0~15th bits are alright.

 

Dose anybody know how to fix it??

Plz tell me, any clue about these kinds of the problems

Re: WARNING: Par:288 -IBUF has no load

Maybe the missing bits of wbi_dat_i have been removed during the synthesis. Check it in the .syr file.
