while hunting for the software I had used before, I ran across a newer 
paper by Toroysan and Wilson titled "Exact analysis of DDS spurs and SNR 
due to phase truncation and arbitrary phase-to-amplitude errors" , aug 
2005 frequency control symposium.

Toroysan has a patent on a system for designing DDSes too.

Vankka's book/dissertation is online, as well.
