Logic Circuit Simulator

A small React + Vite app to visually design and simulate digital logic circuits using a node-based editor (React Flow / XYFlow).

Features

• Drag & drop logic gates (INPUT, OUTPUT, AND, OR, NOT, NAND, NOR, XOR, XNOR)
• Connect gates with edges (wires)
• Toggle INPUT nodes to propagate signals
• Run simulation and see outputs (LEDs) update
• Save and load circuit JSON

Setup (Windows PowerShell)

1. Install dependencies

cd "c:\Users\SHITANSHU KUMAR\OneDrive\Desktop\logic-circuit"
npm install

2. Run dev server

npm run dev

3. Open the dev URL shown by Vite in your browser.

Notes & Next Steps

• This repo uses Zustand for global state and a simple BFS propagation algorithm.
• Improve: edge coloring, cycle detection, better topological evaluation, UI polish with shadcn components.
