The standard includes guidelines for testing any software components that are part of a medical device. VectorCAST provides intended use validation in the form of qualification documents. Coverage and test case reports are exportable to regular HTML or text for easy integration into product documentation. It is a derivative of the International Electronic Commission document, IEC adapted for the challenges met in railway systems.

EN takes into account the five software integrity levels SIL that range from the very critical SIL-4 , such as safety signaling to the non-critical, such as management information systems SIL EN recommends that software tools such as testing tools be qualified in order to provide evidence of software tool suitability for use when developing a safety-related item or element such that confidence can be achieved in the correct execution of activities and tasks required by EN VectorCAST accelerates testing efforts related to EN compliance by empowering users with the following benefits:.

The new reports use a cascading style sheet. The user is invited to create their own style sheet to set custom colors and fonts. VectorCAST version contains a new test-only symbolic constants feature that allows the user to supply constants stored in a portable file. This feature helps make test cases more portable by replacing hard-coded scalar values with symbols that can be controlled independently of the tests.

VectorCAST now supports the capability to display and graphically visualize control flow and code coverage. This dynamic test solution is widely used in the avionics, medical device, automotive, industrial controls, railway, and financial industries. One of the greatest challenges faced by software groups is reducing time to market for new functionality. Most groups have a backlog of new features that are waiting for release. The bottleneck is often the time that it takes to run a full suite of system tests on a candidate release; often days or weeks. Long test times mean that tests are run late in the release cycle after weeks of changes have been integrated, and often identify blocking defects which cause release delays and unhappy customers.

Software Quality and Testing Completeness are linked. You cannot have quality without complete testing. Development and test tools from Vector have been setting standards in the automotive field for decades now, but they are hardly known in application areas such as medical technology. Since embedded software is playing a continually growing role in that field as well, there is increasing demand for suitable support in developing networked system solutions for medical technology.

That is why Vector is presenting its platform of tools and services for accelerated development and simplified testing of medical electronics at MedtecLIVE in Nuremberg. The automated test platform VectorCAST has been selected by German founded Ottobock as their platform of choice for safety critical embedded software testing. No additional configuration is required.

The kit contains tool qualification plans, tool operational requirements, and additional materials required for qualifying software verification tools. With the kit, development organizations can streamline certification of their embedded systems developed using VectorCAST. The kit includes test procedures, plans, coverage and test case reports necessary for Intended Use Validation, and to demonstrate due diligence with FDA and IEC software quality requirements. Polarion solutions improve the efficiency of product development and help organizations identify and mitigate risks, improve quality, and achieve compliance and quality standards.

Defense committee: Prof. Joseph Sifakis reviewer , Dr. Roland Groz reviewer , Dr. Susanne Graf, Dr. They can represent concurrency in a more intuitive way: two concurrent events are not causally related. Several partial order models are frequently used: Petri nets, Pom-sets, event structures, … It is possible to get back to a transition system representation of a finite partial order representation by considering marking graphs for Petri nets, linearisations of Pom-sets, or configurations of event structures.

Within the project, partial orders are seen as the most natural way for providing a semantics to scenarios MSC, UML sequence diagrams,…. The telecommunication world is evolving rapidly. New worldwide infrastructures connecting multiple components are settling. Mobile communications is also a growing sector and new services are constantly developed. On the software point of view, building a new application from scratch is no longer possible. There is a real need for flexible solutions allowing to deal at the same time with a wide range of needs product lines modeling and methodologies for managing them , while reducing the time to market such as derivation and validation tools.

The Triskell project has gained experience in model engineering, and finds here a propitious domain. The increasing software complexity and the reliability and reusability requirements fully justify the methods developed by our project. The main themes studied are reliable software components composition, UML-based developments validation, and test generation from UML models.

The research activity in Triskell focuses at the same time on development efficiency and reliability. The main applications of this research is clearly related to the telecommunication domain, and mainly concern reliable construction of communication software, and object oriented systems testing.

Reliability is an essential requirement in a context where a huge number of softwares and sometimes several versions of the same program may coexist in a big telecommunication network. On one hand, software should be able to evolve very fast, as new features or services are frequently added to existing ones, but on the other hand, the occurrence of a fault in a system can be very costly, and time consuming.

A lot of attention should then be paid to interoperability, i. We think that formal methods may help solving this kind of problems. Note that formal methods should be more and more integrated in an approach allowing system designer to build software globally, in order to take into account constraints and objectives coming from user requirements.

These methodologies are in their early years. A good example of such techniques is the object oriented approach, which is becoming more popular in the telecommunication world. Software testing is another aspect of reliable development. Testing activities mainly consist in ensuring that a system implementation conforms to its specifications.

Whatever the efforts spent for development, this phase is of real importance to ensure that a system behaves properly in a complex environment. Triskell presentation Research fields In its broad acceptation, Software Engineering consists in proposing practical solutions, founded on scientific knowledge, in order to produce and maintain software with constraints on costs, quality and deadlines. Project-team presentation overview The research domain of the Triskell project is the model driven development of software product lines.

Scientific foundations The Triskell project studies new techniques for the reliable construction of software product lines, especially for distributed and reactive software. Labelled Transition Systems A lts is a directed graph which edges are labelled by letters representing events. Non interleaved models One of the main drawbacks of interleaved models is that concurrency is represented by means of interleavings. References [1] Brad Appleton.
