hello sir thank you for your reply I am generation code from IP catlog then instantiatiating it for my design and then checking the converted digital data in ILA but waveform is not sinusoidal.
I am using XADC in zedboard for getting analog data with XADC wizard in vivado but when i have made the all connection and gave Vp Vn a 1V sinusoidal supply in Vivado I am not get the output only some noise is coming.
