This lab presents Finite State Machines (FSM) and will you have explore a couple Moore machines.
Finite State Machine
- Word problem
- Implement a sequencer (FSM) which controls 3 lights: a green light, a yellow light, and a red light. The lights operate in a cycle, as follows:
- Green is ON for 1 second, and turns OFF. Then
- Yellow is ON for 1 second, then turns OFF. Then
- Red is ON for 2 seconds, and stays ON. Then
- Yellow turns ON for 1 second, and after that both Red and Yellow turn OFF.
Part 1
- Generate the timing diagram, and the state diagram.
- Find the number of flip-flops required to implement the FSM.
- Find the boolean functions that will generate the D inputs to the flip-flops, and the R, G, and Y outputs.
Part 2
- Verify that your design is correct by coding your equations in a Python simulator.
Part 3
- Wire up a circuit that implements this FSM. Demonstrate its correct behavior to your instructor.
