rampe vhdl

hi all

iam new to VHDL and FPGA.
someone plz tell me how to write a program for frequency divider in VHDL.From 100kHz ,i have to reduce to 50Hz.should i write a test bench for it.


also plz tell me how to generate Ramp pulses using VHDL code.


Iam badly in need of these two programs for my seven pulse generator program to run a motor.

If anyone have all these or any of these ,plz upload.

thank you in advance

clock divider vhdl code

From ur post what I guess is you need code for PWM to drive a DC motor.
If I am right you can get VHDL code for PWM from net. Checkout this!
