What is a Logic Circuit Simulator?
This tool is a professional online utility developed for students and engineers learning the basics of digital engineering, allowing them to intuitively build and test digital logic circuits directly in their browser. It supports a wide range of components, from foundational logic gates (such as AND, OR, and NOT) to flip-flops essential for memory circuits. It is ideal for school assignments, preparation for electronic hobbies, or as a learning aid to deepen your understanding of digital electronics.
How to Operate
- Placement & Movement: Drag buttons from the top-left panel or click them to add components. Placed components can be freely moved by dragging them.
- Wiring: Click and drag from the "●" terminals located on either side of a component, then connect it to a terminal on another component to complete the wiring.
- Toggling Inputs: Click a SWITCH to toggle its ON/OFF state (you can also hold the Shift key while clicking).
- Deletion: Right-click a component or wire to delete it individually. Alternatively, you can delete 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 pan the background, and use the mouse wheel to zoom in or out.
- Fullscreen Mode: Click the "FULLSCREEN" button at the bottom right to display the simulator across the entire screen.
Features of This Tool
- No Installation Required: It runs entirely within your web browser, making it accessible from any operating system or device.
- Completely Free & No Registration: All features are available at no cost. You can also save and load your circuit design data.
- Real-Time Simulation: The circuit's behavior updates instantly as you connect components, allowing you to visually identify the logic states by color.
- Privacy-Focused: All processing takes place within your own browser, meaning your circuit design data is never uploaded to an external server.
Step-by-Step Usage Guide
- Select your desired component (such as a SWITCH or an AND gate) from the "IO / Gates" panel on the top left and place it onto the center of the screen.
- Connect the components together using wires and verify that your intended logic path functions correctly.
- Once you have verified the circuit operation, click the "SAVE" button at the bottom right to download and save your work as a JSON file.
- You can load your saved files at any time via the "LOAD" button to resume your design.
Frequently Asked Questions (FAQ)
A. Basic combinational and sequential circuits (such as flip-flops) will operate smoothly. However, performance on extremely large-scale circuits may vary depending on your browser's processing capability.
A. Clicking the "SAVE" button downloads the circuit data as a local file. Please check your browser's download permission settings if the file does not download.
A. The UI is optimized for desktop mouse operations. While it can be viewed on smartphones, a PC environment is highly recommended for precision tasks such as wiring and moving components.
