Model-driven design has significantly enhanced the development process of functional designs, with AUTOSAR providing a respective integration platform. However, modern agile development setups pose a challenge for software architects, requiring continuous evaluation and adaptation of the diverse functional relationships among an increasing number of components. These relationships are only partially represented within the AUTOSAR API and are implemented in project and hardware specific solutions. The Logical Execution Time (LET) paradigm offers a structured approach to support agile design processes, while necessitating a coordinated effort between top-down design and bottom-up integration. In this paper we explore the requirements and propose solutions to address these challenges.
