Design and simulate the work of logic circuits. Create new objects from scratch or upload pre-made projects, customize templates and monitor their simulated functioning. Access and integrate graphical objects that are organized into categories: wiring, gates, plexers, arithmetic, RAM memory, input/output, and base.
Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits. With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used) to design and simulate entire CPUs for educational purposes.
