Generation of PWM waves for electronic circuits using FPGA

This project generates Pulse Width Modulation Waveforms for electronic circuits using Field Programmable Gate Array(FPGA). The coding language used is VHDL on XILINX platform and testing done on ModelSim. PWM waves are majorily used in many electronic gadgets as a supply of clocking signals, mobile phones etc. Implementing it on a FPGA provides speed, high efficiency than other comparable technologies. Most important feature of this project is that this device can be used to provide CLOCK signal to 'N' number of other devices. Hence this device can function as a clock generator as well as Master-Slave clock generator to electronic circuits. A real life scenario where this PWM finds application is in TV, where the user tunes SLEEP option and the TV gets switched off after the required time. This mechanism works using a timer for which clock signal is provided by PWM programmed chip.
