Logisim -Simulate Digital 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.
- The wiring tool draws horizontal and vertical wires, automatically connecting to components and to other wires. It's very easy to draw circuits!
- Circuit layouts can be used as "subcircuits" of other circuits, allowing for hierarchical circuit design.
- Included circuit components include inputs and outputs, gates, multiplexers, arithmetic circuits, flip-flops, and RAM memory.
- The included "combinational analysis" module allows for conversion between circuits, truth tables, and Boolean expressions.
