Uppaal [UPP,BLL98] is an integrated tool environment for modelling, simulating and verification of real-time and hybrid systems, developed jointly by BRICS at Aalborg University in Denmark and by DoCS at Uppsala University in Sweden. In this talk we will review the status of the currently distributed version of Uppaal and describe in more detail the ongoing developments which are to be incorpor...

A prerequisite for successful software development is the availability of a complete and consistent software requirements specification. One way to asses the correctness of requirements specifications is the application of formal verification. Recently, the verification tool Uppaal [12, 16] has become available. Uppaal performs automatic verification of properties of real-time systems through m...

Within the upcoming European Joint Technology Initiative ARTEMIS as well as several national initiatives such as CISS (www.ciss.dk) and DaNES (http://www.danes.aau.dk/), model-driven development is a key to dealing with the increasing complexity of embedded systems, while reducing the time and cost to market. The use of models should permit early assessment of the functional correctness of a gi...

Control synthesis techniques, based on timed games, derive strategies to ensure a given control objective, e.g., time-bounded reachability. Model checking verifies correctness properties of systems. Statistical model checking can be used to analyse performance aspects of systems, e.g., energy consumption. In this work, we propose to combine these three techniques. In particular, given a strateg...

A major problem in model-checking timed systems is the huge memory requirement. In this paper, we study the memory-block traversal problems of using standard operating systems in exploring the state-space of timed automata. We report a case study which demonstrates that deallocating memory blocks (i.e. memory-block traversal) using standard memory management routines is extremely time-consuming...

This document summarizes experiments we performed using XTA input (via GAL transformation) and its-tools to analyze timed automata using discrete time assumptions. We provide comparisons to reference tool Uppaal.

The software development for Cyber-Physical Systems (CPS), e.g., autonomous vehicles, requires both functional and non-functional quality assurance to guarantee that the CPS operates safely and effectively. EAST-ADL is a domain specific architectural language dedicated to safety-critical automotive embedded system design. We have previously modified EAST-ADL to include energy constraints and tr...

Model checking has been attracting attention to analyze signaling pathways. There are two or more, i.e. multiple, signals flowing in a signaling pathway. Most of previous work, however, have treated only one, i.e. single, signal. To analyze a signaling pathway more precisely, it is necessary to treat multiple signals. There is few previous work treating multiple signals. It is known that a prim...

Background Although immunotherapy (IMT) provides significant survival benefits in selected patients, approximately 10% of patients experience (serious) immune-related adverse events (irAEs). The early detection will prevent irAEs from progressing to severe stages, and routine testing for has become common practice. Because a positive test outcome might indicate clinically manifesting irAE that ...
