Digital

It provides a visual environment for creating and simulating digital logic circuits, aimed at educational use and hobbyist experimentation. Users can draw schematics, define test cases, and observe signal waveforms through measurement graphs. The tool supports both combinational and sequential designs, includes a library of common 74xx ICs, and offers a simple finite‑state‑machine editor that can generate corresponding transition tables and circuit implementations.

The application runs on any platform with a Java Runtime Environment (JRE 8 or newer) and requires no installation beyond unpacking a zip file. It can be started directly as a JAR on Windows and macOS or via a shell script on Linux. Additional capabilities include a TCP remote interface for external control, support for custom Java components, and the ability to describe components in VHDL or Verilog when external simulators are installed.

Export options cover VHDL/Verilog code, JEDEC files for GAL and ATF programmable logic devices, and SVG graphics suitable for LaTeX or Inkscape. Examples range from simple gates to a full MIPS‑like single‑cycle CPU and large designs such as Conway’s Game of Life, demonstrating the simulator’s performance and scalability.
