ISO 26262 calibrateable Systems are discussed in part 6 Annex C. This blog summarizes important requirements of the standard and shows practice-oriented challenges of software-configurable embedded systems.
The use of calibration data in configurable systems offers a lot of advantages. The functional behavior of the entire system can be adjusted by simple and rapid changes in the calibration data without having to change the source code itself. This enables the multiple re-use of source code. If it is well done, even the unit tests should be reusable, included the measurement of the structural Source Coverage. These are quite important advantages.

EN 50128 configurable Systems: Chapter 8 of EN 50128 specifies the requirements for systems that are configured by application data or application algorithms (EN 50128 configurable Systems). This blog summarizes the essential requirements of the standard and the practice-oriented challenges of software-configurable embedded systems.
At the first glance the configurability offers only advantages. The functional behavior of the entire system can be adjusted by simple and rapid changes in the application data to the desired behavior. The source code of the generic software is not to changed. A multiple reuse is possible thereby. If it is well done, even the unit tests should be reuseable, without any change. The EN 50128 also states that proven, generic software can be reused repeatedly in this way. These are important advantages. Read more
