A Design Space Exploration Framework For Automotive Embedded Systems And Their Power Management

The E/E (electric/electronic) architecture of a modern vehicle is a complex distributed system, where up to 80 electronic control units (ECUs), interconnected by several communication buses, need to collaborate with each other in order to implement the various comfort and safety features. The presented E/E design space exploration framework supports engineers during the development process of new E/E architectures by providing a graphical modeling and simulation environment with an interactive visualization of simulation-based results. Furthermore, it contains an advanced business logic which administrates the modeling, storing, retrieving and cloning of evaluation sessions consisting of complex experiments. Due to a high-level modeling approach, future architectures can be evaluated in respect to power consumption and performance values already in an early stage of the design process and design alternatives can be easily compared with each other.
