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...

I can't recognise any problems from your pictures. I expect the output to transition after the clk edge. That is what it does but gets close in front of next clk edge(Tco of register is several ns) such that you think it changes before clk edge.
