Draw and simulate a logic circuit with gates and flip-flops to see how signals flow through it in real time.
Enter a truth table and let Digital automatically synthesize the equivalent logic circuit.
Export a circuit design to VHDL or Verilog and load it onto an FPGA board for physical hardware testing.
Use the built-in finite state machine editor to design a controller, then convert it directly into a working simulation.

Requires Java installed, download the zip, unpack, and launch the JAR, no installer needed.
Digital is a desktop application for drawing and simulating digital logic circuits. It is aimed at students and educators learning how computers work at the level of logic gates: AND, OR, NOT, flip-flops, and similar building blocks. You draw a circuit visually, then run it and watch signals flow through it in real time. The application requires Java to run but needs no installer: you download a zip file, unpack it, and launch the included JAR file. It runs on Windows, macOS, and Linux. The README lists a long set of features, including signal measurement graphs that show how values change over time, a single-step mode for tracing through a circuit one gate at a time, automatic analysis and synthesis of logic circuits from truth tables, and a built-in editor for finite state machines that can be converted directly into working circuits. Digital also ships with a library of 74xx series chips, which are a family of real-world integrated circuit parts commonly used in electronics courses. Circuits can be exported to VHDL or Verilog, which are hardware description languages used to program actual programmable logic chips. The tool has direct support for two specific hobbyist FPGA boards, so a circuit designed in Digital can be loaded onto physical hardware. It can also export JEDEC files for older programmable logic chips that are still used in beginner exercises. The project was created as a response to Logisim, an older educational logic simulator whose original developer stopped working on it in 2014. The author cites architectural limitations in Logisim as the reason for starting fresh rather than contributing to one of the existing forks. Several examples are bundled with the application, ranging from basic flip-flops to a complete simple processor, all with included test cases. Documentation is available in English, German, Spanish, Portuguese, French, Italian, and simplified Chinese. The README notes that the documentation is still incomplete but includes a getting-started chapter covering basic usage.
