Exercise 3 (2 pts) Download the SL Exercise 3 starter circuite. It should have no inputs and one 4-bit output pin with four 1-bit inputs consolidated using a splitter. Modify the circuit so that the four outputs, when put together, form a binary number that increases by one each clock cycle, unless it is already at 15 (four 1s in a row), in which case it goes back to 0 (four Os in a row). The circuit should start in a state where it outputs all Os. Usual reminders: Exercise 3 (2 pts) Download the SL Exercise 3 starter circuite.
