Spot

Spot is a C++11 library for ω-automata manipulation and model checking. It has the following notable features:

  • Support for LTL (several syntaxes supported) and the linear fragment of PSL.
  • Support for ω-automata with arbitrary acceptance condition.
  • Support for transition-based acceptance (state-based acceptance is supported by a reduction to transition-based acceptance).
  • The automaton parser can read a stream of automata written in any of four syntaxes (HOA, never claims, LBTT, DSTAR).
  • Several algorithms for formula manipulation including: simplifying formulas, testing implication or equivalence, testing stutter-invariance, removing some operators by rewriting, translation to automata…
  • Several algorithms for automata manipulation including: product, emptiness checks, simulation-based reductions, minimization of weak-DBA, removal of useless SCCs, acceptance-condition transformations, etc.
  • In addition to the C++ interface, most of its algorithms are usable via command-line tools, and via Python bindings.
  • One command-line tool, called ltlcross, is a rewrite of LBTT, but with support for PSL and arbitrary acceptance conditions. It could for instance be used to test tools that translate LTL into Rabin automata.

Latest version

The latest version is {{{LASTRELEASE}}} and was released on {{{LASTDATE}}}. Please see the download and installation instructions.

Documentation

On-line LTL/PSL translator

  • Our on-line translator provides a convenient way to translate LTL or PSL formulas into automata, without installing Spot.

License

Spot is distributed under a GNU GPL v3 license.

A consequence is that if you distribute a tool built using Spot, you must make the source code of that tool available as well.
