    What's the easiest way to implement an NCO (numeric Controlled Oscillator)
    in VHDL?

    Dunno, but it's always a lot easier if you take
    a few moments to list the specification:

    - output waveform (square wave, sinusoid, ...?)
    - reference frequency
    - output frequency range and resolution
    - output jitter requirements

    You'll find many discussions of NCO design
    in the archives of comp.lang.vhdl and
    comp.arch.fpga - it's well-trodden ground.
