Practice-Oriented Formal Methods To Support The Software Development Of Industrial Control Systems
2017
Zenodo
Preserved Fulltext
Model checking, one of the main formal verification techniques, is computationally difficult, therefore the analysis of non-trivial systems requires special considerations. ...
Furthermore, the mainly academic tools implementing different model checking algorithms are not suitable for users who are not experts in formal methods. ...
Although the use of model checking for PLC-based industrial control software was already studied in e.g. ...
