Configuration of Model Checking Sample Clauses

Configuration of Model Checking. ‌ In principle, applying model checking to a multi-model requires three impor- tant configuration steps: • The multi-model containing the different components has to be im- ported into the INTO-CPS Application. • The abstractions to be applied to the multi-model have to be config- ured 2. • The LTL specifications have to be defined. Figure 7 shows the dialog to configure the desired abstractions. The example is based on the RT-Tester turn indication lever model, which models turn indication functionality based on three inputs (found under Stimulation in Fig. 7): • A continuous input called voltage is provided, and the turn indica- tion functionality is expected to operate only if the voltage is within the valid range from 9 to 13 [V]. • An integral input TurnIndLever is provided, which indicates the state of the physical turn indication lever. Admissible values range from 0 to 2. • A discrete input EmerSwitch defines whether emergency flashing is turned on, which may to some extent lead to interactions with the core turn indication functionality. In this example, the input signal voltage of type float is to be fed using values from a concrete execution, the log of which is stored in a file called signals.json. The abstraction is configured so that values within an interval of 2 units are used for discretization of the signal.
