Logic Circuit Simulator

A logic circuit simulator useful for educational use.

This is a fork followed by an almost complete rewrite of drendog's Logic-Circuit-Simuator.

Demo

Development

• Checkout with git
• npm install
• Open VS Code and open folder
• npm run compile-watch to run the TypeScript compiler (without output) to check for errors
• npm run lint-watch to run eslint to check for linting errors
• npm run bundle-watch to build the bundle with esbuild (can be done on every save because esbuild is so fast)
• npm run server to serve locally for testing on port 8088

Differences with Original Version

• This fork is completely written in TypeScript
• Based on web components so that it can easily be embedded by pulling in a single JS file
• Dependency on p5 was removed
• Interface is drawn differently, all with canvas calls and no external images
• Screen is only refreshed when needed and not 60 times per second no matter what
• Clocks can be paused
• Components have been added: bit display, segment display, nibble display, half adder, muxes, register, RAM, counter, various decoders, etc.
• Size of components (in terms of number of bits) can be changed
• RAM/ROM contents can be loaded from files
• Mouseover tooltips have been added
• Components can be edited to be faulty, for educational exercises
• Editor can be in several modes with different capabilities
• Component buttons can be hidden or shown for educational purposes with URL parameters
• Loading and saving using JSON is much cleaner and does not include unnecessary properties
• Demo circuits are predefined and can be loaded from the JavaScript console
• Circuits can be loaded from a JSON export by drag-n-drop
• An animated propagation delay can be set
• Custom components can be created, loaded, saved from library files
• Tests for a given circuit can be defined (or automatically generated) and run
• UI can be in English or French (easy to add more translations)
• Much more
