Digital Logic Builder: Advanced Interactive Simulation
The Digital Logic Builder at CircuitsLab Wiki is a high-performance Electronic Design Automation (EDA) tool designed for students, educators, and engineers. It bridges the gap between abstract Boolean algebra and physical circuit implementation through a unique Bi-Directional Engine.
1. Professional Design Capabilities
- Bi-Directional Logic Processing: Users can input complex Boolean
expressions like
A + (B * C)to generate visual circuits instantly, or draw a circuit manually to have the tool derive the mathematical expression (e.g.,Y = A OR (B AND C)). - Real-Time Signal Propagation: Logic states (0/1) propagate across the infinite canvas with zero latency, utilizing glowing neon wires to visualize signal flow.
- Hot-Swap Gate Replacement: A specialized feature that allows you to drag a new gate directly onto an existing one, instantly swapping the logic type while maintaining all existing wire connections.
2. Technical Specifications & Components
The tool supports a wide array of standardized digital components to facilitate complex system design:
- Basic & Advanced Gates: Includes standard AND, OR, NOT, NAND, NOR, XOR, and XNOR gates, along with high-density 3-Input variants (AND3, OR3, etc.).
- Interactive I/O: High-visibility toggle switches for inputs and glowing LED probes for output verification.
- Smart Wiring System: Features dynamic wire rerouting that recalculates paths 60 times per second to ensure a clean, professional schematic even as components are moved.
3. Workflow & Shortcuts
Designed for speed, the builder utilizes professional-grade shortcuts to streamline the design process:
| Action | Control(s) |
|---|---|
| Pan Canvas | Middle Mouse Button OR Spacebar + Left Click |
| Zoom | Mouse Wheel (Scroll In/Out) |
| Multi-Select | Shift + Click OR Drag Box |
| Build Circuit | Enter Key (within Boolean Input box) |
Digital Logic Builder: Expert FAQ
This section addresses common user queries while strategically targeting high-volume search terms found in your analytics.
General Usage
How do I convert a Boolean expression into a circuit?
Simply type your expression (e.g., A + (B * C)) into the Boolean Input
box
and press Enter. The Bi-Directional Engine will instantly generate
the
corresponding gate schematic on the infinite canvas.
Can the tool derive a Boolean formula from a manual drawing?
Yes. As you build your circuit manually, the tool's Circuit-to-Text engine traces the signal paths and displays the resulting mathematical expression in real-time.
What is "Hot-Swap Replacement"?
This is a high-efficiency design feature that allows you to drag a new gate (like an OR gate) and drop it directly onto an existing one (like an AND gate). The tool replaces the logic type while keeping all existing wire connections intact.
Technical Capabilities
Does the tool support 3-input logic gates?
Yes, the builder supports advanced variants including AND3, OR3, NAND3, and NOR3 for high-density logic designs.
How accurate is the simulation?
The tool features real-time simulation with zero latency. Logic states (0/1) propagate instantly, and wires utilize Smart Rerouting logic that recalculates paths 60 times per second for smooth visualization.
How can I save my design for a lab report?
Use the built-in Export tool to take a high-resolution screenshot of your design. The output is optimized for documentation, featuring a clean, professional aesthetic.

The Physics of Signal Propagation
To provide a modern, "simple but heavy" vibe, our visualizer uses high-contrast neon wires to indicate signal states:
- High (1): Wires glow Red, indicating an active voltage level.
- Low (0): Wires appear Grey, indicating a ground or logic-low state.
Universal Gates and De Morgan’s Laws
The Digital Logic Builder is a powerhouse for testing fundamental laws of Boolean algebra. For example, users can verify De Morgan's Theorem by building and comparing these two equivalent circuits:
NOT (A AND B) ↔ (NOT A) OR (NOT B)
Because the NAND and NOR gates are "Universal," you can use this tool to build any other complex logic gate using only these types—the same principle used in modern CPU and SSD architecture.
