The simulator project is a software project that simulates hardware. The motivation for this program is to teach hardware design in the process of working on a software development project.

Parts are inserted by right-clicking on the grid and selecting a part, such as a logic gate, a seven-segment LED, or an input source. De-Morgan's theorem can be applied to gates to substitute one gate for another, and inverters can be moved to the other in a manner similar to automatic refactoring of software. Also, gates with many inputs can be cascaded or fanned out, or expressed using more primitive gates. The most basic nand gate or not gate can further be represented as a NPN circuit with resistor and transistor images, superimposed over their symbols, superimposed over the gate symbol itself.
