Incorrect Physical resource selection in UltraScale Transceiver Wizard

[gaurav_ag]

Hi 

In my design I have been using a GTH Transceiver generated for Quad 128 for driving Quad 228. 

It seems to be working. 

Can someone please help me understand what is the importance of selecting Quad in the Wizard? 

Thanks

Gaurav

The GT locations are constrained in the example design by the GT wizard. If you try to move the GT you can run into implementation problems. The reason to select the positions of the GT's in the wizard is so that the wizard can make sure you are following all the positioning rules like not crossing SLR boundaries with an interface.
