Exercise: Designing a Simple ASM

Task: Design a simple ASM that controls a vending machine with two buttons (A and B) and one output (DISP).

Requirements:

  • The vending machine accepts two types of coins: A (worth 5 units) and B (worth 10 units).
  • When a coin is inserted, the DISP output should display the current value of the coins inserted.
  • When the total value reaches 15 units, the vending machine dispenses a product and resets the value to 0.

Create an ASM chart that clearly depicts the states, transitions, and outputs of the system. Include the following:

  • States: Define the states based on the total value of the coins inserted (e.g., state 0, state 5, state 10, state 15).
  • Transitions: Define the transitions based on the input buttons (A and B).
  • Outputs: Define the DISP output for each state.

Hint: Use a state diagram to visually represent the flow of the ASM.
