Pulse signal with variable working cycle controlled by a rotary control!

[symba05]

Hello good people of this forum!

I don't have a lot of experience with VHDL and I need some help to create a VHDL code for this situation:


Draw a control circuit that generates a pulse signal with:

fixed working frequency (100 KHz)
variable working cycle
The phase difference should be increased or decreased by the direction of the spin of a rotary control of 8 bits.

Additional info: D = t (on) / T

D = working cycle
t (on) = Time the activated signal lasts
T = signal period (constant)

(see the signal in the image attached)
