Hi!

 

I use the IBUFGDS in my design(virtex-5,IXE10.1.03,ModelsimSE6.2b), but simulation can not success.

Thank you very much!!!

Bassman refers to the following lines in your VHDL sources:

 

Library UNISIM;
use UNISIM.vcomponents.all;

 

Have you included this library declaration in all source code that instantiate Xilinx UNISIM primitives (ibufg, DCM, etc.)?
