Model checking reveals hidden design errors

System verification by testing and simulation covers only a limited number of system behaviours.


Model checking, a computer aided verification method, covers all possible behaviours of the system model. VTT has  successfully applied the method e.g. for the verification of critical nuclear automation systems and factory automation systems.

  • Designers detect design errors in early phase.
  • Revelation of design errors that could have gone undiscovered with only traditional methods.
  • Fast and inexpensive way to try different scenarios with "what-if" analyses.
