“…APP4MC is an open-source Eclipse platform that concentrates on performance simulation regarding mostly scheduling and timing analysis in multi-core platforms using a modelbased development approach (see Figure 6) [76,77]. The hardware and software elements can be modeled, including different properties such as the processor type, connection type among various specified modules, OS schedulers, and task properties such as execution time and deadline.…”

In recent years, the electrical and/or electronic architecture of vehicles has been significantly evolving. The new generation of cars demands a considerable amount of computational power due to a large number of safety-critical applications and driver-assisted functionalities. Consequently, a high-performance computing unit is required to provide the demanded power and process these applications while, in this case, vehicle architecture moves toward a centralized architecture. Simultaneously, appropriate software architecture has to be defined to fulfill the needs of the main computing unit and functional safety requirements. However, the process of configuring and integrating critical applications into a vehicle central computer while meeting safety requirements and optimization objectives is a time-consuming, complicated, and error-prone process. In this paper, we firstly present the evolution of the vehicle architecture, past, present, and future, and its current bottlenecks and future key technologies. Then, challenges of software configuration and mapping for automotive systems are discussed. Accordingly, mapping techniques and optimization objectives for mapping tasks to multi-core processors using design space exploration method are studied. Moreover, the current technologies and frameworks regarding the vehicle architecture synthesis, model analysis with regard to software integration and configuration, and solving the mapping problem for automotive embedded systems are expressed. Finally, we propose four research questions as future works for this field of study.

“…The starting point to developing an update of an automotive function is an Update Cockpit, which is based on the App4MC software (Höttger et al 2017). The update cockpit allows the definition of the application as an updatable unit plus contract-based metadata for the system integration.…”

Automotive software is undergoing a rapid change toward artificial intelligence and towards more and more connectedness with other systems. For both, an incremental design paradigm is desired, where the car's software is frequently updated after production but still can guarantee the highest automotive safety standards. We present a design flow and tool framework enabling a DevOps paradigm for automotive software development. DevOps means that software is developed in a continuous loop of development, deployment, usage in the field, collection of runtime data and feedback to the developers for the next design iteration. The software developers get support in defining, developing, and verifying new software functions based on the data gathered in the field by the previous software generation. The software developers can define contracts describing the time and resource assumptions on the integration environment and guarantees for other dependent software components in the system. These contracts allow a composition of software components and proof obligations to be discharged at design time through virtual integration testing and runtime through continuous monitoring of assumptions and guarantees on the software component's interfaces. An update package, consisting of the software component and its contracts, is then automatically created, transferred over the air, and deployed in the car. Monitors derived from the contracts allow for supervising the system's behavior, detecting failures at runtime, and annotating the situation to be included in a data collection, fueling the next design iteration.

“…An approach has been introduced [11] to solve and op timize mapping issues (i.e., deployment of a safety-critical application on avionics hardware) for distributed systems in the aviation domain. To facilitate the software integration process for multi-core and many-core embedded systems, an open-source tool, called AAP4MC, was proposed [12]. It con tributes to the mapping and partitioning of embedded multi core systems while optimizing the final solution regarding preset optimization goals such as load balancing and energy consumption.…”
