On Managing Performance and Timing in Early- Stage E/E Design - Reducing the Gap Between Requirements and Implementation

摘要

For a long time, tools and methods for automotive E/E design were mostly in the domain of academic researches only. Recently, OEMs have started adopting selected contributions, because (very soon) it will become quite costly NOT to apply them. The first step is establishing centralized data storage for all design data. At present, selecting appropriate abstraction levels and design methods that get fed by and feed the data is the task at hand. In this paper, we summarize recent progress in this selection process with a focus on performance; which is a key aspect for architecture generation. Our contribution provides incremental progress from both ends of the mentioned gap (requirements vs. architecture vs. implementation) towards one another. The presentation is created around the IMES project [21] considering centralized data storage. However, the overall approach is based on established standards and common design patterns as much as possible. We present a flexible methodology template that fits into the E/E design practice, so it can be adopted by any OEMs.
