Abstract

The AUTOSAR standard guides the development of component-based automotive software. As automotive software typically implements safety-critical functions, it needs to fulfill high dependability requirements, and the effort put into the quality assurance of these systems is correspondingly high. Testing, fault injection (FI), and other techniques are employed for the experimental dependability assessment of these increasingly software-intensive systems. Having flexible and automated support for instrumentation is key in making these assessment techniques efficient. However, providing a usable, customizable and performant instrumentation for AUTOSAR is non-trivial due to the varied abstractions and high complexity of these systems. This paper develops a dependability assessment guidance framework tailored towards AUTOSAR that helps identify the applicability and effectiveness of instrumentation techniques at (a) varied levels of software abstraction and granularity, (b) at varied software access levels - black-box, grey-box, white-box, and (c) the application of interface wrappers for conducting FI.

仪器AUTOSAR可靠性评估:指导框架

AUTOSAR标准指导基于组件的汽车软件的开发。由于汽车软件通常实现安全关键功能，它需要满足高可靠性要求，并且在这些系统的质量保证方面投入的努力也相应很高。测试、故障注入(FI)和其他技术被用于这些日益增长的软件密集型系统的实验可靠性评估。为仪器提供灵活和自动化的支持是使这些评估技术高效的关键。然而，由于这些系统的各种抽象和高度复杂性，为AUTOSAR提供一个可用的、可定制的、高性能的检测工具并非易事。本文开发了针对AUTOSAR量身定制的可靠性评估指导框架，该框架有助于确定仪器技术在以下方面的适用性和有效性:(a)不同级别的软件抽象和粒度，(b)不同级别的软件访问级别——黑盒、灰盒、白盒，以及(c)用于执行FI的接口包装器的应用。
