One of the key challenges for manufacturers of automotive systems, hardware components and software products is not only the process of defining explicit and implicit requirements but also the ability to satisfy safety requirements such as those specified in ISO 26262. From an element point of view, the Safety Element out of Context (SEooC) defined in ISO26262 is becoming a reference for developing systems, elements and components in the automotive sector. Integration teams have limited prior knowledge of how these third party devices have been defined, the assumed requirements used during the validation and verification phases. Goal Structuring Notation (GSN) can be used to define and document the assumed SEooC requirements in a graphical manner. However, development teams are facing several challenges for example how different requirements are implemented in SEooC, or how far GSN is able to represent SEooC definitions. This paper provides a GSN based approach to represent SEooC requirements in a practical example of an automotive hall sensor.
