What is a Logic Circuit Simulator?
This browser-based tool is designed for students, hobbyists, and anyone learning the basics of digital logic. It allows you to build and test digital logic circuits directly in your browser by placing components and connecting them with virtual wires. The simulator supports fundamental logic gates such as AND, OR, and NOT, as well as components such as flip-flops used in sequential and memory circuits. It can be used for studying digital electronics, checking circuit ideas, and practicing logic circuit design without installing dedicated software.
How to Operate
- Placement & Movement: Drag components from the panel in the top-left corner, or click a component to add it to the circuit. Placed components can be moved by dragging them.
- Wiring: Click and drag from the ● terminals on a component and connect them to terminals on another component to create a wire.
- Toggling Inputs: Click a SWITCH to toggle its ON/OFF state. You can also hold the Shift key while clicking if supported by the simulator.
- Deletion: Right-click a component or wire to delete it individually. You can also remove components by dragging them to the trash bin icon at the bottom right of the screen.
- Canvas Navigation: Drag with the right mouse button to move around the circuit canvas, and use the mouse wheel to zoom in or out.
- Fullscreen Mode: Click the FULLSCREEN button at the bottom right to expand the simulator to the available screen area.
Features of This Tool
- No Installation Required: The simulator runs in a modern web browser without requiring dedicated circuit simulation software.
- Free to Use & No Registration: You can use the simulator without creating an account. Circuit designs can also be saved and loaded as local JSON files.
- Real-Time Simulation: Circuit behavior is updated as components and connections change, allowing you to observe logic states visually.
- Browser-Based Processing: Circuit simulation and editing are performed within your browser, and circuit design data is not uploaded to an external server as part of the simulation process.
Step-by-Step Usage Guide
- Select a component such as a SWITCH or AND gate from the IO / Gates panel in the top-left corner and place it on the circuit canvas.
- Connect the components using wires and change the input states to check whether the circuit behaves as expected.
- Once you have finished designing the circuit, click the SAVE button at the bottom right to download the circuit design as a JSON file.
- Use the LOAD button to open a previously saved circuit design and continue editing it.
Frequently Asked Questions (FAQ)
A. The simulator is designed to handle basic combinational and sequential circuits, including circuits using components such as flip-flops. Performance may vary with very large or complex circuits depending on your browser, device, and the number of components being simulated.
A. Clicking the SAVE button downloads the circuit design data as a local JSON file. If the file does not download, check your browser's download permissions and available storage space.
A. The simulator can be accessed from modern mobile browsers, but its interface is optimized for desktop mouse operations. A PC environment is recommended for precise tasks such as wiring, moving components, and designing larger circuits.
A. Yes. Use the SAVE button to download your circuit design as a JSON file. You can later use the LOAD button to reopen the saved file and continue editing the circuit.
