Logisim is an educational tool for designing and simulating digital
logic circuits.
Features:
* It is free! (Logisim is open-source (GPL).)
* It runs on any machine supporting Java 1.4 or later; special
versions are released for MacOS X and Windows. The cross-platform
nature is important for students who have a variety of home/dorm
computer systems.
* The drawing interface is based on an intuitive toolbar. Color-coded
wires aid in simulating and debugging a circuit.
* The wiring tool draws horizontal and vertical wires, automatically
connecting to components and to other wires. It's very easy to draw
circuits!
* Completed circuits can be saved into a file, exported to a GIF file,
or printed on a printer.
* 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.
