My research teacher ask for a PWM using fixed point. Today I'm using pulse-width modulation (PWM) to control the brightness of an LED using VHDL. I'm using the Lattice iCEstick FPGA development board.Click the Digital outputs can either go ON or OFF. Analog signals, on the other side, can smoothly assume multiple values in a range. There is a technique that emulates analog behavior with a digital output.

In case of a 50 MHz clock, a 200 µs pulse with about 50 Hz repetition. By using an unregistered comparator, the output will have some glitches, you may want to correct it.

The input signal “ i_pwm_module ” is used as the terminal counter value for the PWM counter. Pulse Width Modulation (PWM) is a very popular modulation technique which is mainly used to control the power delivered to electrical devices such as motors. This VHDL project presents a simple VHDL code for PWM Generator with Variable Duty Cycle. The VHDL code for PWM Generator is simulated and verified on Xilinx ISIM. This details a pulse width modulation (PWM) generator component for use in CPLDs and FPGAs, written in VHDL.

Pulse-width modulation (PWM) is an efficient way of controlling the power to analog devices like motors or LEDs from purely digital FPGA pins using VHDL. Parameter of VHDL PWM code The generic parameter “ N ” set at compile time the number of bit of the PWM counter. This parameter set the maximum number of bit of the PWM counter. The input signal “ i_pwm_module ” is used as the terminal counter value for the PWM counter.
