This activity can contribute towards your Continuing Professional Development (CPD) as part of the IET's CPD monitoring scheme

The AURIX™ microcontroller generation implements almost all computation safety mechanisms to detect single-point faults in hardware, but some software support is required to access them. We cover the basic process needed to apply it in real systems.

The AURIX™ microcontroller hardware and SafeTlib software are intended to be used together as an element of an Electrical/Electronic (E/E) system as defined by the functional safety standard ISO 26262 “Road vehicles – Functional safety”. It is developed as a Safety Element out of Context (SEooC) in accordance with the ISO 26262-10.

This application note introduces AURIXTM SafeTlib and FMEDA and covers the basic process required to apply them in real systems to meet safety goals.
