General presentation of the field

The Spot library ( contains many algorithms for translating LTL formulas into Büchi automata, and to simplify these formulas and automata. It also provides support to build a LTL model-checker, through algorithms testing whether the language of such an automaton is empty or not.

The model-checking process takes a model of a system and a LTL formula to check, and outputs either "correct" if the property holds, or a run of the system on which the property does not hold (a counter-example).


This internship targets students who:

  • have some experience in Web development and/or C++ and/or Python (conjunction is favored over disjunction)
  • would like to get familiar with the amazing world of model-checking
  • would like to popularize model-checking and formal methods

We wish to build an interactive demonstration prototype for Spot, to illustrate the interest of model-checking. The targeted use-case is the verification of a controller for lifts.

The prototype should provide several functionalities, among which: - a graphical representation of the system and its evolution, - a way to specify a controller and to check temporal properties by calling Spot. - the capability to replay (graphically) a counter-example given by Spot. - the ability to describe the characteristics of the lifts system (number of lifts, ranges etc.)

Such a prototype is intended to be used in the communication of the LRDE, for example during the Journées Portes Ouvertes.
