IBUFDS module declared in IP core wizard generated module

Jump to solution

Dear all,

 

I am using ISE 12.2 and design kit SP605 for GTP applications.

 

The GTP Transceiver wizard generated a module and it will use external SMA clock input. The differential SMA input will be buffered by a IBUFDS module based on my understanding.

 

During the thynsis, the XST tool reported the module is not delcared.

 

I tried to delcare the component but strangly the module name IBUFDS is shown in brown colour and it is the same in the original wizard generated core.

 

So how can I solve this problem? Is there any head file or library I should included in the design?

 

Thanks to all in advance!

The problem is solved by using library UNISIM

 

library UNISIM

use UNISIM.Vcomponents.ALL

 

And there are some non-synthesable componets in the GTP transceiver because the generic part needs to be set to 0 for synthesis and 1 for simulation.
