Description
ISO 26262 is an automotive standard that was released in November 2011 and has as target to make cars safer. This point is especially important when thinking about the actual trend towards more and more autonomous cars where the amount of safety critical electronics is increasing quickly and where the impact of potential safety critical failures is very high. Wrong decisions taken by the electronic systems can have an important impact on the people inside and outside of the car. The purpose of the standard is, by focusing on systematic and random hardware failures, to help reducing the risk of safety critical malfunctions to an acceptable level. The standard proposes to achieve this through a series of work products and through robust design methods of the system itself and its electronic sub-components.
The target of this presentation is to give a quick overview of the purpose and content of the standard and to explain how it relates to semiconductor mixed-signal developments. A general flow will be presented which starts from a safety concept and ends with an architecture that achieves a high diagnostic coverage. The core of the presentation will be dedicated to explaining the challenges to perform a functional safety analysis according to ISO 26262 and present the work products that are recommended by the standard. Also some time will be spent during the presentation to explain the impact of the safety analysis on the architecture of the component under development and to understand when enough has been done to make the device safe.
