The project consists of a 50 MHz chronometer in which minutes, seconds and hundredths of a second are shown through six 7 segment displays. It can be initialized or paused pressing the start button, pressing the reset button will cause it to restart the counter.
For testing the chronometer project connect push buttons to the reset and bt_ent (start button) inputs. It is designed to work with six 7 segment common cathode displays. Unidirectional output pins must be connected to displays cathodes. Bidirectioanl output pin must be connected to displays anodes.
You need six 7 segment common cathode displays, push buttons.
