Logisim – Free Circuit Schematic Designing and Simulating Software

Early this month we reviewed TinyCAD, which is a freeware for designing circuit diagram. Logisim( LODJ-uh-sim ) is a free, open source, lightweight, easy-using, cross-platform, multi-language and portable alternative to TinyCAD which is suitable for students, it can be used to create larger circuits, hierarchical circuits and wire bundles.
