Architectural models, such as those described in the east language, represent convenient abstractions to reason about automotive embedded software systems. To enjoy the fully-fledged advantages of reasoning, EAST-ADL models could benefit from a component-aware analysis framework that provides, ideally, both verification and model-based test-case generation capabilities. While different verification techniques have been developed for architectural models, only a few target EAST-ADL. In this paper, we present a methodology for code validation, starting from EAST-ADL artifacts. The methodology relies on: (i) automated model-based test-case generation for functional requirements criteria based on the EAST-ADL model extended with timed automata semantics, and (ii) validation of system implementation by generating Python test scripts based on the abstract test-cases. The scripts represent concrete test-cases that are executable on the system implementation. We apply our methodology to analyze the ABS function implementation of the Brake-by-Wire system prototype.
