Logisim

What is Logisim?

Logisim is a comprehensive educational tool for designing and simulating digital logic circuits. It offers a simple, intuitive toolbar interface that allows users to easily construct and simulate digital circuits as they build them. The software supports the creation of larger circuits from smaller subcircuits and provides the capability to draw bundles of wires with a single mouse drag, making it a powerful tool for designing and simulating entire CPUs for educational purposes Logisim is widely used by students at colleges and universities around the world, across a variety of classes, including general-education computer science surveys, computer organization courses, and full-semester courses on computer architecture. Its cross-platform compatibility, which allows it to run on any machine supporting Java 5 or later, ensures accessibility for students with diverse home or dorm computer systems
