Early problem detection
The data-based synthesis tool checks the specification for common issues, for early detection of problems that will lead to an empty supervisor. If such a problem is detected, a warning is printed to the console. Among others, checks are included for no initial states/variables, no marked states, and no states due to the state requirement invariants. To skip printing these empty supervisor warnings, configure the Output mode option to only print errors (General category).
The tool also checks whether there are events that are never enabled in the input specification. If such a problem is detected, a warning is printed to the console. Among others, checks are included for events that are forbidden by automaton guards, event/state exclusion plant and requirement invariants, and state plant invariants. To skip these event checks, disable the Event warning option (Synthesis category).
The tool furthermore checks for plant invariants or plant automata that reference requirement state. If such a problem is detected, a warning is printed to the console. Among others, references in guards, updates, invariant predicates, initialization predicates, marker predicates and initial values for discrete variables are detected. To skip these reference checks, disable the Plants referencing requirements warnings option (Synthesis category).
