Sinewave Generation using DDS and observing on DAC for ZCU111

Hi

I am working on ZCU111 board. I made the following schematic to generate a sinewave using DDS. I do not know how to proceed further to check the output on DAC. Do I need to do any software part? I am using Vivado 2019.1. If I generate the bitstream, what shall I do next? Kindly help me.

After generating the bitstream, you can download into your ZCU111 card, and check the output of DAC which corresponds to the DAC which you assign in the IP Data Converter.

Also, there are a lot of methods to verify the signal at the DAC:

You can simulate your design in Vivado using Vivado Simulator, or a spectrum analyzer. If you don't have a spectrum analyzer you can use a loopback design to check it
