Tasks
Instructions
  • The input bits A1, A0 (the number A) and B1, B0 (the number B) start at 0. Click on an input bit to toggle its value between 0 and 1.
  • 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.
  • The three outputs show whether A = B, A > B or A < B. Exactly one of them is 1.
  • When the simulation finishes, the outputs are shown. Change the inputs and click on Start again to try another combination.
  • Reset - Resets the simulation and sets all the inputs back to 0.
