Step-by-step Logisim-evolution tutorials: gates, circuits, FSMs and CPU projects.
Getting Started with Logisim-evolution: Your First Circuit This tutorial walks you through building your first working circuit in Logisim-evolution: two switches feeding an AND gate, with a lamp showing the result. It takes about ten minutes and needs no prior experience. What you need Download and install Logisim-evolution first (version 5.0.0 or newer). If you…
Chronogram & Timing Analysis in Logisim-evolution Watching LEDs blink tells you that a circuit works. The Chronogram — Logisim-evolution’s built-in timing diagram — tells you when everything happens: signal waveforms plotted against time, so you can see propagation delays, glitches, and the exact ordering of events across clock edges. It is the tool you reach…
Clean Up Your Circuits: Tunnels and Splitters in Logisim-evolution Every beginner circuit looks fine until it grows: wires cross the whole canvas, the clock line snakes around three components, and moving one gate breaks five connections. Tunnels and Splitters (both in the Wiring library) fix this. They are the difference between a schematic you can…
ROM Tutorial: Store and Read Data in Logisim-evolution ROM (Read-Only Memory, in the Memory library) holds fixed data that your circuit can read but never changes while running. It is where CPUs keep their programs: the address input selects a row, and the stored value appears on the data output a moment later. If you…
Comparator Tutorial: Compare Two Numbers in Logisim-evolution The Comparator (Arithmetic library) answers one question: how does value A relate to value B? It has two multi-bit inputs and three 1-bit outputs — > (A greater than B), = (equal), < (A less than B). Exactly one of them is high at any time. It is…
How to Build a Digital Clock in Logisim-evolution A digital clock is the perfect second project after your first logic-gate circuit. It uses three components you will meet in almost every later design: the Clock, the Counter, and the Comparator. By the end of this tutorial you will have a six-digit clock counting real seconds,…
