CADDi is an online academic CAD tool that is able to generate the ladder diagram of an electrical circuit. It can be done in two different ways:

  • CADDi offers a novel easy-to-use language for programming electrical circuits, called WDLang.
  • CADDi allows the user to graphically build a ladder diagram.

Once the ladder diagram is built, CADDi allows checking its functionality thanks to its interactive interface, that allows taking actions on the different elements of the circuit just by clicking with your mouse.
