NCO:Sine Waveform

Hi. I am trying to use the NCO to generate the sine waveform. However, the waveform obtained is different where it is attached. May i know where to modify it in order to get the correct the sine wave...

From the timing analysis, everything seems fine. However, i just wonder on the tco. It takes 7.334ns.

If that is the case, when running the clk on 25MHz, from the simulaiton, it takes only 1.5ns for the delay instead of 7.334ns. Any reason?

Can someone clarify on it? i am not so good on analyze timing analysis.

thanks a lot
