A large class of embedded systems has safety, availability, reliability, timing and performance requirements. Timing analysis is needed in many steps of the development process; it is a key to rapid designing and prototyping of embedded systems, to reduce system overall cost through efficient resource management (especially: tradeoffs when co-developing hardware and software), to find bottlenecks in the software, and to validate that the system meets its timing requirements. There is a growing awareness of the importance of correct timing for these systems, however, there is still a lack of efficient methods and tools for timing assessment and validation that can be used in European industry. The existing timing analysis technology by far does not exploit the potential inherent in European research results and timing tools. The ALL-TIMES project aims at combining and developing research results and timing tools currently available and thus to strengthen the European lead in the timing analysis area. The ALL-TIMES project will enable interoperability of tools from SMEs and universities, and develop integrated tool chains using open tool frameworks and interfaces. By combining research results and commercial tools, ALL-TIMES will ensure the flow of ideas from basic research to practice. ALL-TIMES will strengthen the competitiveness of several key industries in Europe, not only the automotive and aerospace areas (where partial awareness already exists) but also automation, manufacturing, robotics, medical, communication, and multimedia, and other market areas where timing is of importance.

The proposed RECOMP (Reduced certification cost for trusted multi-core platforms) research project will establish methods, tools and platforms for enabling cost-efficient certification and re-certification of safety-critical systems and mixed-criticality systems, i.e. systems containing safety-critical and non-safety-critical components. RECOMP recognizes the fact that the increasing processing power of embedded systems is mainly provided by increasing the number of processing cores. The increased numbers of cores is commonly regarded as a design challenge in the safety-critical area, as there are no established approaches to achieve certification. At the same time there is an increased need for flexibility in the products in the safety-critical market. This need for flexibility puts new requirements on the customization and the upgradability of both the non-safety and safety-critical critical part. The difficulty with this is the large cost in both effort and money of the re-certification of the modified software, which means that companies cannot fully leverage the advantages of modular software system. RECOMP will provide reference designs and platform architectures together with the required design methods and tools for achieving cost-effective certification and re-certification of mixed-criticality, component based, multi-core systems. The aim of RECOMP is to define a European standard reference technology for mixed-criticality multi-core systems supported by the European tool vendors participating in RECOMP. The RECOMP project will bring clear benefits in terms of cross-domain implementations of mixed-criticality systems in all domains addressed by project participants: automotive systems, aerospace systems, industrial control systems, lifts and transportation systems. RECOMP will thus provide solutions that will allow European industry to increase its market share in the growing market of mixed-criticality systems.

SAFURE targets the design of cyber-physical systems by implementing a methodology that ensures safety and security by construction. This methodology is enabled by a framework developed to extend system capabilities so as to control the concurrent effects of security threats on the system behaviour. The current approach for security on safety-critical embedded systems is generally to keep subsystems separated, but this approach is now being challenged by technological evolution towards openness, increased communications and use of multi-core architectures. The objectives of SAFURE are to (1) implement a holistic approach to safety and security of embedded dependable systems, preventing and detecting potential attacks; (2) to empower designers and developers with analysis methods, development tools and execution capabilities that jointly consider security and safety; (3) to set the ground for the development of SAFURE-compliant mixed-critical embedded products. The results of SAFURE will be (1) a framework with the capability to detect, prevent and protect from security threats on safety, able to monitor from application level down to the hardware level potential attacks to system integrity from time, energy, temperature and data threats; (2) a methodology that supports the joint design of safety and security of embedded systems, assisting the designer and developers with tools and modelling languages extensions; (3) proof-of concept through 3 industrial use cases in automotive and telecommunications; (4) recommendations for extensions of standards to integrate security on safety-critical systems; (5) specifications to design and develop SAFURE-compliant products. The impact of SAFURE will help European suppliers of safety-critical embedded products to develop more cost and energy-aware solutions. To ensure this impact, a community will be created around the project. SAFURE comprises 7 industrial manufacturers, 4 leading universities and research centres and 1 SME.

New technologies such as multi-core and Ethernet provide vastly improved computing and communications capabilities. This sets the foundation for the implementation of new digital megatrends in almost all areas: driver assistance, vehicle dynamics, electrification, safety, connectivity, autonomous driving. The new challenge: We must share these computing and communication capacities among all vehicle functions and their software. For this step, we need a good resource planning to minimize the probability of late resource bottlenecks (e.g. overload, lack of real-time capability, quality loss). In this article, we summarize the status quo in the field of resource management and provide an outlook on the challenges ahead. Copyright © 2016 SAE International.

More electronic vehicle functions lead to an exponentially growing degree of software integration in automotive ECUs. We are seeing an increasing number of ECUs with mixed criticality software. ISO26262 describes different safety requirements, including freedom from interference and absence from error propagation for the software. These requirements mandate particular attention for mixed-criticality ECUs. In this paper we investigate the ability to guarantee that these safety requirements will be fulfilled by using established (deadline monitoring) and new error detection mechanisms (execution time monitoring). We also show how these methods can be used to build up safe and efficient schedules for today's and future automotive embedded real time systems with mixed criticality software.

Ethernet is considered as a future communication standard for distributed embedded systems in the automotive and industrial domains. A key challenge is the deterministic low-latency transport of Ethernet frames, as many safety-critical real-time applications in these domains have tight timing requirements. Time-sensitive networking (TSN) is an upcoming set of Ethernet standards, which (among other things) address these requirements by specifying new quality of service mechanisms in the form of different traffic shapers. In this paper, we consider TSN's time-aware and peristaltic shapers and evaluate whether these shapers are able to fulfill these strict timing requirements. We present a formal timing analysis, which is a key requirement for the adoption of Ethernet in safety-critical real-time systems, to derive worst-case latency bounds for each shaper. We use a realistic automotive Ethernet setup to compare these shapers to each other and against Ethernet following IEEE 802.1Q. © 2015 IEEE.

Increasing demand for performance and further integration promotes the use of multi- and many-core systems - also in safety-critical embedded systems. In this domain, hardware platforms obviously have to support real-time, predictability constrained applications such as an anti-lock braking system. However, the on-going trend to integrate multiple functions with different criticalities (mixed critical) on a single platform calls for a paradigm shift. Mixed-critical systems require special attention with respect to functional (access protection) and non-functional (performance) isolation. An additional layer of protection and guaranteed service on the underlying infrastructure enables the efficient adoption of such architectures in safety-critical domains. In this paper, we present the IDAMC, a many-core platform which provides mechanisms to integrate applications of different criticalities on a single platform. © 2013 IEEE.

The sound decomposition of system level timing requirements, including end-to-end deadlines, into local timing requirements and latency budgets is a key automotive design challenge. In this paper, we analyze the technical and organizational influences on the end-to-end deadline decomposition. We will identify and assess typical design options. From this, we provide two key contributions: First, we provide guidelines for the decomposition and the application of design rules. Secondly, we analyze the specific requirements and specialties of different use cases. The findings of this paper enable optimizations and traceability of timing requirements through the entire Electrics/Electronics (E/E) design cycle. This is a prerequisite for reliable, cost-efficient automotive system design. Copyright © 2012 SAE International.
