Abstract
Within the scope of CBMD, the 伟德国际_伟德国际1946$娱乐app游戏 of Augsburg has investigated, among other things, how contracts between different components can be validated during their composition. Furthermore, it was investigated how contracts as interface state machines fit together with the specification of the behavior (state machine) of the component. In the course of the project, it became apparent that contracts also make a significant contribution in the context of security. For example, a check of the contracts at runtime can rule out the possibility of a component being operated "incorrectly". Due to dependencies, however, it can also happen that a function of one component calls a function of another component without the call being made via the interface secured with a contract. Therefore, in this project, a static analysis of the dependencies in the code with integration into the Contracts is to ensure that, firstly, security-relevant functions and data of a component and, secondly, side effects between components can be identified and subsequently checked and analyzed in more detail by tests on the real system.

Abstract
In recent years, Cyber Physical Systems (CPS) technologies have become a game changer in strategic sectors such as Automotive, Energy and Industry Automation, where Europe is a world leader. In fact, CPS is a key driver for the innovation capacity of European industries, large and small, generating economic growth and supporting meaningful jobs for citizens.
?
CPS4EU proposes to address technical issues and organizational issues in an integrated way. Hence, CPS4EU promotes a high level of sharing, so that an operational ecosystem, with adequate skills and expertise all along the value chain can enable, at the end of the project, the European industry to lead strategic markets based on CPS technologies.
?
The ultimate objective of CPS4EU is to strengthen the CPS value chain by creating world class European SMEs and by providing CPS technologies that in turn will sustain the leadership of the large European groups in key economy sectors and, in this way will stimulate innovative products to support the massive digitization increasingly integrated into our everyday environment.
?
To achieve these goals CPS4EU will:
- Develop 4 key enabling technologies (computing, connectivity, sensing, cooperative systems)
- Incorporate these CPS modules through pre-integrated architectures and design tools
- Instantiate these architectures in dedicated use cases from strategic application: automotive, smart grid and industry automation
- Improve CPS awareness and usage for all industrial sectors

Abstract
The aim of this research project is to automate the evaluation of existing tests ("Test the Test", T3) by means of Fault Injection as well as mutations of the test object (system under test) on the software side and on the hardware side to improve the quality of the tests. To this end, existing approaches to software and hardware tests will be supplemented by a quality analysis of test cases in order to meet the ever-increasing security requirements of embedded systems and to adapt the tests semi-automatically to the test results.
?
In addition to the classical approaches for determining test quality, T3 aims at a better way of evaluating tests. On the one hand, this is to be done by means of so-called "front-loading" of test activities, i. e. tests in early phases of development (design time) and their evaluation. On the other hand, a (semi-)automatic improvement of the test quality is to be achieved by appropriate adaptation and combination of classical code metrics. This evaluation is to be made possible in a similar way across different integration levels. To this end, the results of these developments will be integrated into specific existing software and hardware testing tools of the project partners. The results are evaluated through case studies.

Abstract
Nowadays software functions are not operated in isolation from each other, but usually there are a multitude of dependencies between them. For the manufacturers of individual functions, as well as for the function integrator, it is therefore very difficult to impossible to completely oversee all interactions between the inherent states. This results in complexity effects such as emergence, common mode effects, unwanted activation of operating states, hidden links and dis-functionalities. The aim of the project is therefore to define and implement a hierarchically organized, computer-based development platform for SW-intensive systems that implements the contract-based design paradigm consistently and formally. Accordingly, the platform should be structured hierarchically as well as modularly in order to be able to follow both a top-down (new development) and a bottom-up development process (existing components/subsystems) and to contain all necessary design and test modules that are necessary to carry out the development steps across all process levels in the sense of the CBD paradigm. Evaluation takes place via a case study.

Abstract
AUTOSAR ("Automotive Open Systems Architecture") is the de facto standard for automotive ECU software and provides a consistent software architecture as well as uniform description and configurations formats. However, there is a shortage of tools which work directly on AUTOSAR models and do not use proprietary (and often simplified) intermediate models.
Together with the Continental Automotive GmbH, our professorship developed a tool named "AutoAnalyze", which conducts a data-flow analysis on the most fine-granular AUTOSAR level, visualizes the dependencies between the functional blocks, detects potential data consistency conflicts and provides support for resolving them, e.g., by imposing, modifying or removing timing constraints. Hereby, the model is being validated for an execution on single- and multi-core platforms.
Most often, an intended execution on multi-core platforms does not lead to software being re-created from scratch but rather to migrating existing legacy software. Therefore, our tool also supports the required working steps of partitioning (splitting the software into a disjoint set) and mapping (assigning the software parts to cores/execution units) with the help of a previously performed region analysis as well as derived initial solutions from it.

Abstract
It is common knowledge in Software Engineering that the earlier in development an error of a system is found, then the lower are the costs for its correction. This is especially the case if the system under development is an embedded or safety critical one, where not only a system’s software, but also its corresponding documentation or hardware is affected by changes.
In this context, Model-Driven Development (MDD) aims to shift most aspects of a system’s software implementation into earlier phases of the development e.g., software design or system design. Therefore, we concentrate in this work on shifting the timing and inter-component communication aspects of a system’s software from the implementation phase to the system design phase of a project.
Our approach uses the Architecture Analysis and Design Language (AADL), which is specifically designed for the specification, analysis, automated integration and code generation of real-time, performance-critical distributed computer systems. AADL offers – among other things – standardized semantics for timing and inter-component communication aspects of software components. In our approach, we utilize these semantics to define a mapping between the AADL and the Real-Time Specification for Java (RTSJ). RTSJ is an extension of standard Java for hard and soft real-time applications. With an implementation of this mapping, we then generate AADL semantic-compliant RTSJ code, which preserves the timing behaviour and intercomponent communication defined in an AADL model. Thus, a system designer is capable of designing and performing analyses regarding communication and timing almost completely during design phase, while resting assured that the implementation will reflect his design choices. Simultaneously, programmers are relieved of the monotonic and repetitive task of writing communication- and timing-related code.
The application of our approach is shown via the implementation of an autopilot for quadrocopters. For this purpose the software of the quadrocopter is modelled in AADL and is then generated by our implementation. The case study shows three advantages of our approach over an implementation without code-generation:
- The speed-up of development by letting the programmer focus on application logic instead of writing recurring code concerned with timing and communication.
- A less error-prone transition from the design of a system to its implementation.
- The possibility of an earlier detection of timing- or communication-related errors in the system.
Our further research is aimed at integrating safety-related aspects e.g., error-propagation, into our existing approach by exploiting Java’s exception mechanisms and RTSJ’s asynchronoustransfer- of-control (ATC) mechanisms.
