sin waveform simulation result

I confused with the sine wave simulation result(frequency domain) between the display of NCO in IP toolbench and agilent vee simulation result(data extracted from tbl). The spec for sin wave i...

I am not particular on the frequency axis because the sine wave in time domain is correct. Besides, i have no idea to map the time and fsin_o to perform fft where i think is time consuming.

My intention is just to estimate the quality of sine wave(e.g distortion and SNR ...).

I have attached the flow on how i perform fft and data extracted from tbl(simulation result).

Thanks
