We are currently working on a project in hopes of altering the Reference Design using the no-OS method on a Xilinx Vertex-7 (VC707) so that a square wave can be transmitted, rather than the original sine wave. Our knowledge of the Xilinx board is fairly limited at the time being.
The main question we have is about the source of the sine wave being transmitted. The signal is created from a lookup table, however we were hoping to find the location of this table and understand how the reference design reads/derives values from it. Any help is greatly appreciated. Thanks.
