FPGA wave generator precision

[schr0dinger_cat]

Hello,

I am trying to implement a FPGA project that requires signal frequency precision levels of about 1 mHz.  Due to the data types in the project, I seem to be having difficulty adjusting the frequencies of the Labview FPGA sine and square wave generators by 1 mHz; the specified frequencies (for example, 999.998 Hz) get binned to the closest available number (for example, 999.996 Hz).  I would like to change frequencies by only 1 mHz.  Is this possible with an FPGA project?  Any help would be much appreciated.

did you check out http://zone.ni.com/devzone/cda/epd/p/id/6066

notice figure 9 for computation of accumulator increment.  how are you trying to solve it?  what hardware?

This seems to be a possible solution to my problem.  I'll have to investigate a bit more, but it looks promising.  Thanks for your help.
