Chapter 1: Transceiver and Tool Overview
there are packages with all the GTH Quads located in a single column along one side of the
die, and other packages with all GTH Quads located on both the left column (X0) and right
column (X1) of the die.
There are two ways to create a UCF for designs that use the GTH transceiver. The preferred
method is to use the Virtex-6 FPGA GTH Transceiver Wizard (see
Transceiver Wizard, page
example design. The UCF file generated by the Wizard can then be edited to customize
operating parameters and placement information for the application.
The second approach is to create the UCF by hand. When using this approach, the designer
must enter the location constraint for the GTH transceiver used in the application.
