Uppaal is an integrated tool environment for modeling, validation and verification of real-time systems modeled as networks of timed automata, extended with data types (bounded integers, arrays, etc.).

About

Uppaal is an integrated tool environment for modeling, simulation and verification of real-time systems, developed jointly by Basic Research in Computer Science at Aalborg University in Denmark and the Department of Information Technology at Uppsala University in Sweden.

It is appropriate for systems that can be modeled as a collection of non-deterministic processes with finite control structure and real-valued clocks, communicating through channels or shared variables.

UPPAAL Verifier

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…

Can't find what could cause the "caused by an out-of-range assignment or out-of-range array lookup." error

I get this error when I try to check my system for deadlocks: The verification was aborted due to an error. Most likely, this is caused by an out-of-range assignment or out-of-range array lookup. I understand what this error is supposed to mean…

Read/Write Data from/to File in Uppaal (For Data Log)

How to write some data into a file as a log or some statistics in Uppaal? Is there any fprintf function or some FILE* such as we have in C or not? The same question for reading from the file too.

Value passing through channels

According to http://www.it.uu.se/research/group/darts/uppaal/small_tutorial.pdf There is no value passing through the channels but this is easily encoded by shared variable: define globally a variable x, and use it for reading and writing. " The…

CSP-like synchronizations

I'm trying to use CSP-like synchronization mechanism and I don't understand why the initial state of the following model is a deadlock: const int N = 2; chan a; process Processes(int [1,N] pid) { state A, B; init A; trans A -> B { sync…

How does Uppaal clock evolve? I have two locations 1 and 2 without invariant. What is clock value?

How does Uppaal clock evolve? I have two locations 1 and 2 without invariant, a clock reset to zero (0) on the transition into location 1. On the edge between location 1 and 2, how do I know the value of the clock at this time? (That is, the value…

UPPAAL SMC avoid State Space Explosion

I am trying to query a larger system with UPPAAL SMC and it ends up with a "memory exhausted" error message. By nature, UPPAAL SMC should not result in a state space explosion that's why I am asking if it is possible to query with SMC without…
