Sine cosine Wave generation using VIVADO only

Hello, I am new to Redpitaya board. I am trying to generate SIne cosine wave from DDS in Vivado.
The output of DDS is AXIS stream(16bit) and when i simulate this i can see a prefect wave. But when i connect the output of DDS to Redpitaya DAC(14bit) the generates wave is not same as the output of DDS.
The DAC output is cosine wave filled. When i go deep and check it is like small triangular waves forming a Cosine wave.
Please help me to get the correct waveform.

Hi,
Please note that not all Red Pitaya models have 14 bit output.

What model do you have?
can you post the code here so our dev can take a look at it?
