Lechef - Logic Circuit Exercise Framework for visualizing and creating exercises on logic circuit basics in JavaScript

lechef - JavaScript Logic Circuit Exercise Framework

The lechef framework helps in creating exercises for learning logic circuits. You can create exercises for simulating a circuit's behavior and exercises for designing circuits. Check the documentation for a more thorough description, examples, and instructions on how to use it.

Here are the components (or, gates) currently supported by the framework: NOT, AND, OR, NAND, NOR, XOR, EQV, and input and output

And here's an example of an exercise. In the exercise, student's task is to toggle the input/output values of each gate to match the correct values of the given input to the circuit. Note: This is only an image, see the docs for interactive examples.

lechef's Issues

Circuit with feedback loops causes output simulation to loop forever

The output simulation used in both simulation and design exercises is stupidly implemented (idiot me!). If a circuit has feedback loops, it will simulate forever.

Support for multiple output components in exercises

The exercises currently assume only one output of the circuit. This is limiting in the kind of components and circuits can be used. For example, the existing half-adder and half-substractors cannot be properly used.

Support for arbitrary number of inputs for components

Most of the components (except output and NOT) should support (almost) arbitrary number of inputs instead of the currently fixed two inputs. Also, the editor should allow changing the number of inputs.
