Apply 11/12A: Simulating a Combinational Lock
Build an electronic combination lock with a reset button, two number buttons (0 and 1), and an unlock output. The combination should be 1011. Overlapping patterns are allowed.
"0"-
"1"_
RESET
UNLOCK A
1. Draw the state diagram of the lock FSM. To keep the design simple, use a single input X to the FSM with the following definition: X=0 means Button"0" pressed, X=1 means Button "1" pressed.
2. Show the state / transition table.
3. Use K-maps to find the next-state and output logic expressions.
4. Implement the lock in CircuitVerse, using DFFs. Take a snapshot. Verify that the lock FSM works as expected.
