How it works
The washing machine controller is a modular digital system implemented in Verilog using a finite-state-machine (FSM). The system simulates a simplified washing process and automatically progresses through different washing stages. If the door is closed, which should be simultaed through a lever, the start button can be pressed. If wanted, the duration of the washing process can be changed, by using the lever.
How to test
Use 1 button for Start and 2 lever for mode_select and for door_closd. Use LEDs to see the output.
