Instructions
- The BCD input bits A, B, C and D start at 0 (A is the most significant bit). Click on an
input bit to toggle its value between 0 and 1.
- Only the BCD codes 0000 to 1001 (digits 0 to 9) are valid. If a larger value is set, the
simulation does not start and a message is shown.
- Start - Starts the simulation for the selected inputs. While it runs, the same
button pauses and resumes it.
- Select the speed (1x, 2x or 4x) from the dropdown menu, before or during the simulation.
- When the simulation finishes, the decoded digit is shown. Change the inputs and click on
Start again to try another digit.
- Reset - Resets the simulation and sets all the inputs back to 0.
