Digital is an educational application for creating and simulating digital logic circuits. Its graphical environment allows users to construct electronic designs from individual logic components and investigate their behaviour.
The software is designed for teaching and learning digital electronics, although it also provides capabilities useful for more advanced projects. Users can develop processors, controllers and complex sequential systems while testing how different parts of a circuit interact.
Digital also bridges the gap between graphical circuit design and hardware development. Designs can be analysed, verified and converted into hardware descriptions suitable for use with compatible development tools.
This is free and open source software.
Key Features
- Interactive graphical editor for combinational and sequential logic circuits.
- Measurement graphs visualise signal states during simulation.
- Single-gate mode helps analyse oscillations and circuit behaviour.
- Analyse and synthesise combinational and sequential circuits.
- Create automated test cases to verify circuit correctness.
- Finite state machine editor with circuit generation.
- Library of common 74xx series integrated circuits.
- Generic circuits allow reusable components with configurable parameters.
- Supports large designs containing thousands of active components.
- Create custom circuit components implemented in Java.
- Remote TCP interface enables external programs to interact with simulations.
- Support for components described using VHDL and Verilog.
- Export circuits to VHDL and Verilog for hardware development.
- Support for FPGA boards and programmable logic devices.
- Export circuit diagrams as SVG graphics.
- Cross-platform support – runs on Linux, macOS, and Windows.
