3.6. Finite State Machine (FSM) Design in Verilog

Try these first

1. 1.

   What are the two types of FSMs discussed?

   Hint

   Think about how outputs are determined.

2. 2.

   Describe a Moore machine's characteristic.

   Hint

   Consider how it differs from a Mealy machine.

3. 3.

   What does a Moore machine depend on for its outputs?

   • Current state
   • Input signals
   • Both current state and input signals

   Hint

   Remember how outputs are determined.

4. 4.

   True or False: A Mealy machine's outputs depend only on the current state.

   • True
   • False

   Hint

   Think of how this affects the output's responsiveness.

5. 5.

   Design a finite state machine for a simple vending machine that accepts coins, dispenses items, and returns change. Provide a Verilog implementation.

   Hint

   Consider user inputs and the transitions required for different coins.

6. 6.

   Explain how you would test your FSM design effectively. What considerations would you make?

   Hint

   Think about how to ensure each state and transition is tested.
