BetterSIS banner


Bettersis, or bsis for short, is an interactive shell that allows you to control SIS (the tool for synthesis and optimization of sequential circuits) more easily than its default shell thanks to modern features such as:

  • command autocompletion
  • command history
  • command suggestions

This snap is bundled together with SIS itself. If you would prefer to use your SIS installation with betterSIS instead please check out the other ways to install betterSIS here: (This is also where you can find betterSIS' source code)
