UPPAAL Verifier

Question

I have a model in the UPPAAL software, and try to verify whether items[2] == 3 in every case. I've tried with that: A<>(items[0] == 0 and items1 == 0 and items[2] == 3)

I made a "closing" state (for every template) and the model goes there whether items[2] == 3. From that state there is no outwards. If i read the documentation correctly A<> exactly should find this state and there check whether items[2] == 3.

Do you know what im doing wrong?

I checked and it is the only deadlock/livelock

Thanks in forward!

what do you mean by "every case"? every path? every state? – mariusm Jun 15 '20 at 07:27 — mariusm, Jun 15 '20 at 07:27
i mean at the end of every path – b_doma Jun 15 '20 at 10:21 — b_doma, Jun 15 '20 at 10:21

A<> property may become false if there is a deadlock or an infinite trace avoiding the state property.

Try enabling the Diagnostic trace in Options, then check the property again and inspect the trace in the simulator. Beware of deadlocks, infinite delays and infinite loops (the last steps appear highlighted in red).
