I have set in the parameters in the NCO megafunction as per my requirements. After that I have Generated the HDL and then designed the schematic(attached).

You don't need schematic, use hdl design

1. The output of the NCO is a 16 bit output. So I would have to give this output to a DAC to generate the analog sinewave form. As far as i have understood this NCO output is parallel. Would I need a parallel to serial converter, if so how do I implement it?
2. After the Analysis and Synthesis, in the Pin planner how do I make the pin assignments for these 16 pin outputs ? The 16 bit DAC provided in the development kit has a serial input (DAC_DIN) is what I have gathered from the data sheet.

if DAC input is single bit then you need to serialise the 16 bits to one, DAC clock should be 16 times faster than NCO and you must provide word boundary

3. Since I was unable to figure this out, I tried to simulate the NCO in modelsim and i have been getting errors(2 of them attached others are similar). Would I have to write some verilog code for simulation (I have assumed that the Generate HDL does it all so I have only written the SDC file with create clock and derive pll clock) or for the nco algorithm? What am I missing here?
4. Is there any other way other than Modelsim to simulate and check whether my design is working.

modelsim compiles hdl desings
