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.).
UPPAAL CORA is a branch of UPPAAL for Cost Optimal Reachability Anslysis developed by the UPPAAL team as part of the VHS and AMETIST projects. Whereas UPPAAL supports model checking of timed automata, UPPAAL CORA uses an extension of timed automata called LPTA. LPTA allows you to annotate the model with the notion of cost.
This can be the cost of delay in certain situations or the cost of particular actions. UPPAAL CORA then finds optimal paths matching goal conditions.
UPPAAL CORA has been used in a number of case studies. Some of these are described on the case study page of this site. If you come up with interesting uses, please contact us. We are interested in hearing what you do!
Due to different internal data structures, UPPAAL CORA currently consists of two different versions:
A version for the simplified case of time optimal reachability analysis.
A version for the full language of LPTA.
Like UPPAAL, UPPAAL CORA is free for non-profit use, e.g. for evaluation, research, and teaching purposes.
Here are some key features of "UPPAAL":
UPPAAL CORA with full LPTA support has a number of limitations. These limitations are not fundamental, but are a result of using new internal data structures with a currently limited feature set. Over time, these limitations will be resolved.
- No extrapolation, hence termination is not guaranteed unless you guarantee that either:
- Simple reachability only:
- Limited use of guiding:
