Creating sound for a game

I want to be able to create 4 sounds at different frequencies/notes in VHDL. The DAC is all setup with 16bits but i'm just stuck with the wave generation. Any wave will do, i just need a few audible tones.

I have experience of using the audio CODEC on the DE2. That bit is ok.

    you can generate waves with the NCO megafunction in dsp. Or if you are ok with NES-era sound you can easily make square and triangle waves in logic in different frequencies.

    Cheers for the reply. I managed to get it done using a lookup table. Worked a treat
