Calculation of AD9914 Spurs

I'm interested in programming the spurious calculations as performed by ADI SimDDS for the AD9914 to allow exhaustive spur search and design optimization.  Is there guidance on your calculations?

Thank You

    See application note AN-1396.

    Be aware that ADIsimDDS only shows spurious associated with DAC harmonics (and their Nyquist images) and primary phase truncation (PPT) spurs. Exhaustive treatment of spurious involves full treatment of phase truncation spurs, which is well beyond the capability of ADIsimDDS.
