Beginner's tutorial
Welcome to Logisim-evolution
Logisim-evolution allows you to design and simulate digital circuits. It is intended as an educational tool, to help you learn how circuits work.
To practice using Logisim, let's build a XOR circuit - that is, a circuit that takes two inputs (which we'll call x and y) and outputs 0 if the inputs are the same and 1 if they are different. The following truth table illustrates.
x | y | x XOR y |
---|---|---|
0 | 0 | 0 |
1 | 0 | 1 |
0 | 1 | 1 |
1 | 1 | 0 |

But just because it's on paper doesn't mean it's right. To verify our work, we'll draw it in Logisim and test it. As an added bonus, we'll get a circuit that's looks nicer than what you probably would draw by hand.
