Simple Logic Circuit Simulator with truth table generator
This is a simple logic circuit simulator with realtime circuit simulation for combinational and sequential circuits. The simulator can also produce truth tables and boolean equations expressing the simulated circuit.
Simple logic sim is written in entirely in javascript, and relies on HTML5 Canvas to render. Jquery libraries are imported for the purpose of easier form input.
Demo
A live demo version is available HERE!.
Tools
Add - brings up GUI to select a component to add
Remove - Click on a component or wire to delete from the sim
Move - Click and drag components to move them around
Logic Input (click to toggle value)
Logic Output (Required to generate truth tables)
Features
Generate truth tables of your circuit
- Truth tables require that the circuit be combinatorial in nature
- Only circuits attached to Logic Input AND Logic Output are processed
Select between straight and square wire appearance
Change simulation speed to see logic circuits in action
- lower delay means the sim runs faster
- higher delay means the sim runs slower
Documentation
Currently WIP but here are some tips:
- Circuits are modeled as directed graphs
- Boolean Equations trees are constructed with outputs as the root node, inputs are leaf nodes
- On evaluation, cyclic detection algorithm is run on the graph to ensure the drawn circuit is purely combinatorial
- Inputs are iterated over via binary counter to evaluate the truth table states
