Logisim-evolution is a free, open-source digital logic design and simulation application that enables users to create, test, and analyze electronic circuits through an intuitive graphical interface. Developed as an enhanced continuation of the original Logisim project, the software provides tools for designing combinational and sequential logic circuits using gates, switches, registers, memory components, and other digital building blocks. Logisim-evolution allows users to simulate circuit behavior in real time, visualize signal changes with timing diagrams, and troubleshoot digital designs before implementing them in physical hardware. The application supports VHDL components and FPGA board integration, allowing users to define circuit behavior using hardware description languages and test designs on compatible electronic boards. Users can create reusable subcircuits, organize complex designs, load custom component libraries, and interact with simulations through a TCL/TK console.
Features
- Graphical Digital Circuit Design: Create and edit digital logic circuits using an interactive schematic editor with drag-and-drop components, wiring tools, and reusable subcircuits.
- Real-Time Logic Simulation: Simulate combinational and sequential circuits, toggle inputs, monitor outputs, and observe how digital signals behave during circuit operation.
- Timing Diagrams and Signal Analysis: Visualize changes in digital signals using chronograms and timing diagrams to analyze circuit behavior and troubleshoot logic problems.
- FPGA and VHDL Integration: Define component behavior using VHDL and integrate with supported FPGA development boards to test circuit designs on physical hardware.
- Extensive Component Libraries: Access built-in digital components, including logic gates, registers, memory, LEDs, switches, TTL devices, and system-on-chip components, with support for custom libraries.
- Cross-Platform Support and Customization: Run Logisim-evolution on Windows, macOS, and Linux, with multilingual interfaces, TCL/TK console integration, and customizable circuit components.
