Background: Logic Gate Simulator is an open-source tool for experimenting with and learning about logic gates. The simulator tool was originally designed for CIS students at South Puget Sound Community College but is free for anyone to use and modify under the GPL v3. Logic Gate Simulator is written in C#/WPF using .NET 4 Watch a 3 minute video demonstration Dave Jordan has implemented a multiplier, download am.gcg
Selected Features: Graph circuit activity over time Drag-and-drop gate layout and wiring User created "integrated circuits" for re-use Viewing the activity inside ICs during simulation Adjustable simulation speed and zoom Print and export as image Cut/copy/paste Inline ICs and flatten entire circuits New in 1.4: A variety of visual modes: including isolating partial circuits to show use, hiding intermediate gates, and not showing different colors for true/false (useful for preparing circuits for use in documents).
Similar Projects: Logic Gate Simulator is one of many similar learning and simulation systems, such as: Logicly (the inspiration for this project) (logicly has been rewritten as a desktop app) Cedar Logic LogiSim QUCS
