FAQ
Answers to common questions.
What is LogicDrawer? Is it a free logic circuit simulator?
LogicDrawer is a completely free, web-based digital logic circuit designer, simulator, and analysis tool. It's an online logic simulator that runs directly in your browser, no downloads or installation required. Perfect for students learning digital logic design, educators teaching circuit theory, and engineers prototyping logic circuits. Design combinational and sequential circuits with real-time simulation and instant feedback.
What AI-powered features does LogicDrawer offer?
LogicDrawer features advanced AI circuit recognition and generation. Upload hand-drawn circuit sketches and our YOLO-based computter vision automatically detects and converts them into functional circuits. Extract circuits from truth table or Karnaugh map images using AI. Generate circuits from natural language descriptions using Gemini AI. Get intelligent circuit suggestions and automatic error detection with our AI assistant.
What logic gates and components are available in LogicDrawer?
LogicDrawer includes comprehensive digital logic components: basic gates (AND, OR, NOT, NAND, NOR, XOR, XNOR), buffer gates, multiplexers (2:1 MUX, 4:1 MUX), decoders, arithmetic circuits (half adder, full adder, half subtractor, full subtractor), sequential logic (D flip-flops, D latches), input components (toggle switches, push buttons, clock generators, constants), and output displays (LEDs, RGB LEDs, hex displays, 7-segment displays, light bulbs). All components support multi-bit logic for advanced circuit design.
What analysis tools does LogicDrawer provide?
LogicDrawer offers professional circuit analysis tools: automatic truth table generation with CSV and PNG export, Karnaugh map (K-map) visualization with Boolean expression minimization, circuit-to-Verilog HDL conversion for hardware synthesis, real-time signal simulation and logic flow visualization, error detection and validation, and step-by-step circuit evaluation. Perfect for logic circuit analysis, digital design homework, and exam preparation.
Can I save, export, and share my circuit designs?
Yes! LogicDrawer supports multiple export formats: save circuits as JSON files for later editing, export to Verilog HDL code for FPGA/ASIC synthesis, download high-quality PNG screenshots of your circuits, export truth tables as CSV or images, save Karnaugh maps as images, and share circuits publicly in our community repository. Import circuits from JSON or Verilog files. All save/load operations work offline after initial page load.
Is LogicDrawer suitable for education and learning digital logic?
Absolutely! LogicDrawer is designed as a free educational tool for digital logic education. It's ideal for computer science students, electrical engineering courses, logic design classes, and self-learners. Features include interactive tutorials, visual circuit simulation, instant feedback, truth table generation for homework, K-map solver for Boolean algebra, keyboard shortcuts for efficient design (Ctrl+S to save, Ctrl+E for Verilog export), and a helpful AI assistant to explain logic concepts. Used by students and educators worldwide for learning combinational logic, sequential circuits, and digital system design.
