Delta method for PWM in VHDL

[lorenaiulia]

Hi!
I am new to this forum. I have a question if anyone could help me...
I want to implement the delta method (sigma-delta method is also good) for pulse width modulation in VHDL (for a Spartan 3 board). Could anyone help me on this matter, or at least give me some helpful links?
I can find diagrams of feedback systems, but no information of actual block diagrams suitable for VHDL.

Cheers,
Lorena

Lorena,

If you can provide some links to the diagrams and info you know about, I may be able to help you develop the VHDL.
