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.
