- Developing automotive software is becoming in- creasingly challenging due to continuous increase in its size and complexity. The development challenge is amplified when the industrial requirements dictate extensions to the legacy (previously developed) automotive software while requiring to meet the existing timing requirements. To cope with these challenges, sufficient techniques and tooling to support the modeling and timing analysis of such systems at earlier development phases is needed. Within this context, we focus on the extension of software component chains in the software architectures of automotive legacy systems. Selecting the sampling frequency, i.e. period, for newly added software components is crucial to meet the timing requirements of the chains. The challenges in selecting periods are identified. It is further shown how to automatically assign periods to software components, such that the end-to-end timing requirements are met while the runtime overhead is minimized. An industrial case study is presented that demonstrates the applicability of the proposed solution to industrial problems.

- Model- and component-based software development has emerged as an attractive option for the development of vehicle software on single-core platforms. There are many challenges that are encountered when the existing component models, that are originally designed for the software development of vehicular distributed single-core embedded systems, are extended for the software development on multi-core platforms. This paper targets the challenge of extending the structural hierarchies in the existing component models to enable the software development on multi-core platforms. The proposed extensions ensure backward compatibility of the component models to support the software development of legacy single-core systems. Moreover, the proposed extensions also anticipate forward compatibility of the component models to the future many-core platforms.
