Logicly for Windows

Brief overview

Logicly is a digital circuit simulator that simplifies the design and learning of logic circuits for both newcomers and experienced users. It provides a clear, visual workspace and a straightforward click-and-drag editing style that makes building and testing circuits fast and intuitive. The interface is designed so you can quickly see how components interact and how signals flow through your design.

Working in the editor

• To remove parts from your schematic, use the Delete icon on the top toolbar, right-click the canvas and choose the delete option, or press the Delete/Backspace key on your keyboard.
• To select multiple items, click an empty area and drag a selection rectangle around the parts you want, or hold Shift while clicking individual components to add them to the selection.
• To place components, open the component picker on the left, then drag elements onto the editing surface and drop them where you want them.

Components and categories

• Logic gates (AND, OR, NOT, NAND, NOR, XOR, etc.) perform boolean operations on their inputs.
• Flip‑flops and other sequential elements store single-bit data and are used to create stateful circuits.
• Output elements connect to pins and visually indicate the current signal state.
• Input devices transmit high/low signals into the circuit; common types include toggle switches and clock sources that change state either manually or periodically.

Simulation behavior

When you open or create a file, the simulator starts running automatically and propagates signals through connected parts. Circuits that include clocks will begin toggling immediately, so you can observe timing behavior and state changes in real time without manually starting the simulation.

Who benefits from Logicly

Logicly is useful for hobbyists, students, instructors, and professional designers alike. Its simple layout and immediate feedback make it great for teaching fundamental concepts in boolean logic and digital circuits, and for quickly prototyping designs without needing physical chips or breadboards.

Free substitute to consider

If you prefer an open-source or cost-free option, try Logisim — a well-known free circuit simulator that offers many of the same educational and design-focused features.
