Definition :
- A logic simulator is a computer program that allows designers and experimenters to conduct virtual tests of complex digital circuitry before working with any hardware.
Multimedia logic : is a drag and drop out logic design software. You can draw your logic design on the white canvas and then we cam simulate the circuit.
YOU CAN WATCH THIS VIDEO FOR YOUR REFERENCES !!!
There are some links for you guys to get the software with FREE !!!
- After downloaded and installed the software, you open it and will show you this :
- Then, you can draw your own logic design on the white canvas using "Palette" :
SIMPLE STEP ON HOW TO CREATE A SIMPLE "OR" CIRCUIT
STEP 1 : Find logic OR in the palette, click the OR gate and place it(click) on the canvas.
STEP 2: Find the switch and click the switch, place on the canvas near the input of the gate.
The switch would like the figure below.
The purpose of using the switch is to test the truth table. If the switch is flipped up, it means 1 and 0 if it is flipped down.
STEP 3: Find the LED icon and place it front of the output of the gate.
Do not confuse with the 7 LED Segment!
STEP 4: To connect the component, use wire icon to connect each dot to the respective gate. Click at one end and drag to the other end.
STEP 5: Labels the input and output accordingly. Find icon capital A(that refers to Text label) and click next to the input. To edit the text, click the mouse palette on the palette(it will indicate as a selector) and double click the label Text to open Text properties. Type the input label on Text box. Click OK.
STEP 6: Simulate the logic by clicking the Simulate menu, choose Run. Or you can just click the Play button to run the simulation.
Test OR truth table by clicking the switch to see whether LED will light on if the condition met. In this logic, only when the switches is set to 1 then LED will light RED.
To stop the simulation, press STOP button.
This circuit can be saved into .lgi file or printed by using the file menu.
