Speed Control of DC mOtor

[ksunil.patro]

Hi,
I am doing a FPGA Model for speed Control Of Dc Motor using PWM technique. Anyone can help me for the source code for generating the PWM signal using Verilog.

 

[permute]

the most basic is:
1.) have a free running counter.
2.) at cnt = 0, store a control value.
3.) while cnt < control value, out = 1. else 0.

This prevents a change in the pwm control input from double pulsing.
