Architectural and Timing Analysis Frameworks for Deterministic Automotive Embedded Systems: A Comprehensive Study of End-to-End Delay, Model-Based Engineering, and Multicore Resource Management

Abstract

The evolution of automotive systems into highly complex, distributed, and software-intensive platforms has significantly increased the demand for deterministic timing behavior and predictable system performance. Modern vehicles integrate numerous electronic control units (ECUs), sensors, and actuators, interconnected through heterogeneous communication networks and operating under stringent real-time constraints. This paper presents a comprehensive analytical study of architectural and timing analysis frameworks for automotive embedded systems, focusing on end-to-end delay analysis, model-based system engineering, and multicore resource management. Drawing upon existing literature, the study investigates compositional frameworks for delay calculation, cause-effect chain analysis, and model-driven methodologies such as EAST-ADL and MoVES. Additionally, it explores the challenges posed by multicore architectures, including memory bandwidth contention and scheduling complexities in mixed-criticality systems. The integration of fault-tolerant architectures, such as dual-core lockstep systems, is also examined to understand their impact on timing predictability and system reliability. The findings reveal that while existing frameworks provide valuable tools for early-stage analysis and system design, significant challenges remain in achieving accurate and scalable timing analysis in increasingly complex automotive systems. The paper highlights the need for unified methodologies that integrate architectural modeling, timing analysis, and resource management, and proposes future research directions aimed at enhancing predictability, scalability, and safety in next-generation automotive systems.
