Simulation of the Full Adder

1.: Open the Logic Simulator.
2.: Use the Select Component botton on the Waveform Viewer within the simulator window to add signals to the Waveform Viewer, Figure 16.
3.: Use the Select Stimulators botton on the Waveform Viewer to associate inputs with keyboard keys, Figure 17.
4.: Initialize the inputs to LOW using the keys you selected.
5.: Set the simulation step to 100ns.
6.: Use the step button and the input keys to simulate the functionality of the full adder.
7.: Close the simulator when done.
