Websettling, causing bounce. Debouncing, of course, is the process of removing the bounces, of converting the brutish realities of the analog world into pristine ones and zeros. Both hardware and software solutions exist, though by far the most common are those done in a snippet of code. Surf the net to sample various approaches to debouncing. Mechanical switches / buttons cause an unpredictable bounce in the signal when toggled. There are various ways to implement debouncing circuits for buttons on FPGA. In this project, a simple debouncing circuit is implemented in Verilog to generate only a single pulse when pressing a button on FPGA.
