KLogic is an application for building and simulating digital circuits easily.
It provides an easy way to build circuits containing standard components like AND, OR, XOR and flipflops like RS and JK. To build more complex and reusable circuits, you can create sub-circuits.
The simulation runs permanently by default while building your circuits. For extended testing you can use a single stepping simulation to recognise peaks. You can display the signal flow of the components of a circuit as a graph. Each device of your circuit has a tunable delay. With the burst option the delay of all devices can be disabled.
