LogiSim - FAST NUCES

Project Overview

LogiSim is a Java Swing-based logic circuit simulator developed as a semester project for Software Construction and Development.
The application allows users to create, visualize, and simulate digital logic circuits using standard components such as logic gates and connectors.
It supports multiple circuits per project, sub-circuits, and provides truth table analysis for designed circuits.
