3.2 Using the VGA Interface

This example creates a circuit that displays the contents of the XS Board RAM on a monitor
through the VGA interface of the XStend Board. The ABEL code for this example is shown in
Listing 16; Listing 17 and Listing 18 show the UCF files for using the XS40 and XS95 Boards
with the XStend Board, respectively.
