IBUFG as ? component

Mar 03, 2005 3 Replies

Instantiating IBUFG as a component shows up in ISE with a ? next to it in the navigator since there is no HDL source file for the declared primitive. Why is this?



The design maps/translates and works fine on the card.


Just put the " use UNISIM.VComponents.all; " in the library declaration part it will do the trick..

Moti.

-- synthesis translate_off library UNISIM; use UNISIM.VComponents.all;

-- synthesis translate_on

gives you one warning less during synthesis...

I forgot to mention the "library UNISIM" You got me there ;-))
