Spot is a C++14 library for LTL, ω-automata manipulation and model
|
|
checking. It has the following notable features:
|
|
|
|
- Support for [[file:concepts.org::#ltl][LTL]] (several syntaxes supported) and
|
|
[[file:concepts.org::#psl][a subset of the linear fragment of PSL]].
|
|
- Support for ω-automata with [[file:concepts.org::#acceptance-condition][arbitrary acceptance condition]].
|
|
- Support for [[file:concepts.org::#trans-acc][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 ([[file:hoa.org][HOA]], [[http://spinroot.com/spin/Man/never.html][never claims]], [[http://www.tcs.hut.fi/Software/lbtt/doc/html/Format-for-automata.html][LBTT]], [[http://www.ltl2dstar.de/docs/ltl2dstar.html][DSTAR]]).
|
|
- Several algorithms for formula manipulation including: simplifying
|
|
formulas, testing implication or equivalence, [[https://spot.lrde.epita.fr/ipynb/stutter-inv.html][testing
|
|
stutter-invariance]], removing some operators by rewriting,
|
|
translation to automata, testing membership to the [[file:hierarchy.org][temporal
|
|
hierarchy of Manna & Pnueli]]...
|
|
- Several algorithms for automata manipulation including: product,
|
|
emptiness checks, simulation-based reductions, minimization of
|
|
weak-DBA, removal of useless SCCs, acceptance-condition
|
|
transformations, determinization, [[file:satmin.org][SAT-based minimization of
|
|
deterministic automata]], etc.
|
|
- In addition to the C++ interface, most of its algorithms are usable
|
|
via [[file:tools.org][command-line tools]], and via [[file:tut.org][Python bindings]].
|
|
- One command-line tool, called [[file:ltlcross.org][=ltlcross=]], is a rewrite of [[http://www.tcs.hut.fi/Software/lbtt/][LBTT]], but
|
|
with support for PSL and automata with arbitrary acceptance
|
|
conditions. It can be used to test tools that translate LTL into
|
|
ω-automata, or benchmark them. A similar tool, [[file:autcross.org][=autcross=]], checks
|
|
tools that transform automata.

* Try Spot On-line
|
|
|
|
- [[http://spot.lrde.epita.fr/trans.html][Our on-line translator]] provides a convenient way to translate LTL or
|
|
PSL formulas into automata.
|
|
- [[http://spot-sandbox.lrde.epita.fr/][spot-sandbox]] is a Jupyter notebook with a complete installation of
|
|
Spot that allows you to try the [[file:tools.org][command-line tools]] (using a shell
|
|
interface) as well as the Python bindings (in an IPython notebook).
