DIGITAL LOGIC SIMULATOR

Multimedia logic is a drag and drop logic design software. You can draw your logic design on the white canvas and then we can stimulate the circuit.

To draw the circuit you need to choose which component needed to built the circuit. The mouse pointer indicates as selector. Use this to select and move icon. To delete an icon , use selector and select the icon. Once an icon is selected, press the delete button on your keyboard.

STEP 1

Find the logic AND in the pallete, click the AND gate and place it on the canvas

STEP 2

Find the switch and click the switch, place the switch on the canvas near the input of the gate.the switch would look like the figure below

STEP 3

Find the LED icon and place on the output side of the gate.

STEP 4

To connect each component, use wire icon to connect each dot to the respective gate. Click at one end and drag to the other end.

STEP 5

Label the input and output accordingly. Find icon “A” and click next to the input. To edit the text, click the mouse pointer on the palette and double click the label text to open text properties. Type the input label on text box, then click OK.

STEP 6

Stimulate the logic by clicking the stimulate menu, choose run. Or you can just click the play button to run the stimulation.

Test the AND truth table by clicking the switch to see whether LED will light on. LED will light on if the condition is met. In this logic, only when all switches is set to 1 then the LED will light red.

To stop the simulation, press stop button.

The circuit can be save into .lgi file or printed by sing the file menu.
