DDS Waveform Generation Reference Design for LabVIEW FPGA

[srm@viewpointusa.com]

Hello,

I recently reviewed the DDS example.  Looks good and I will be able to use it.  However, I think there is a problem with the reset accumulator code.  The reset acts on the next value of the accumulator and will therefore produce the current point using the previous value of the accumulator.  I have attached a suggested change.  The timing changes considering that the data flow changes slightly.
