Antares is a learning platform for digital circuits. In addition to drawing and simulating digital circuits, Antares places particular emphasis on providing tools to help students better understand how these circuits work.


Supported Platforms

Antares is a desktop application for Windows and macOS. The installation programs include the entire required runtime environment; installation of additional components like Java JRE is not required.


The following objectives are pursued in the design of Antares:

  • Aesthetically pleasing circuit representation
  • As few elementary basic components as possible, but libraries with “explorable” components
  • Research into innovative ways of making the functioning of hierarchical systems understandable

The ultimate goal of Antares is to facilitate interactive textbooks with active circuit elements and integrated exercises.
