Hi,

Thanks Luciano. I am aware of the Freewares available and the application is a product. However the issue is a little different. Its all about the scope of a 16F performing DDS. Without using much of additional circuitry.
Mark thanks for the link. The scope of the project does not permit to use it. Otherwise I would have gone for waveform generator chip. Also it is hard to find (if not impossible) in low quantities (less than 0.5K). If I at all go on with this project then I would be going for a 18F with a R-2R DAC.
