Last Updated Sep 24, 2025
Example:
A,0,B means transition from A to B on input 0.

The Simple Finite State Machine Visualizer tool allows users to input states, transitions, initial, and final states to instantly generate and visualize the corresponding finite state machine (FSM) diagram. This tool is essential for educators, students, and engineers to intuitively understand, debug, and communicate FSM logic in computational theory, digital design, or automate process modeling. Usage involves filling form fields with FSM parameters and transitions, followed by clicking "Draw FSM" to display the interactive graphical representation.

How to use this tool?

Complete Guide to Using the Simple Finite State Machine (FSM) Visualizer Tool

  1. Enter States:
    In the "States (comma separated):" field, input all states of your FSM separated by commas.
    Example: A,B,C
  2. Set the Initial State:
    In the "Initial State:" field, enter the state where your FSM starts.
    Example: A
  3. Define Final States:
    In the "Final States (comma separated):" field, list all final (accepting) states, separated by commas.
    Example: C
  4. Input Transitions:
    In the "Transitions (one per line: from,input,to):" box, specify each transition on a new line using the format:
    StateFrom,input,StateTo
    Example: A,0,B
    Add all required transitions, each on its own line.
    Example Input:
    • A,0,B
    • A,1,A
    • B,0,C
    • C,0,C
    Refer to the example given below the input box for clarification.
  5. Draw the FSM:
    Click the Draw FSM button to generate and visualize your finite state machine.
  6. Interpret the FSM Diagram:
    • States: Represented as circles with state names inside.
    • Initial State: Marked with an incoming arrow.
    • Final State(s): Highlighted with a double circle (typically green).
    • Transitions: Directed arrows labeled with the corresponding input symbol.

Troubleshooting Tips

  • Ensure all states specified in transitions exist in the state list.
  • Use correct format: from,input,to (no spaces within the line).
  • Separate multiple final states with commas only.

Example

StatesA,B,C
Initial StateA
Final StatesC
Transitions A,0,B
A,1,A
B,0,C
C,0,C
