Objectives

The objective of the training is to provide participants with the applicable methods and techniques for Part 5 of the ISO 26262 standard, specific to product development at the hardware level. The training focuses on each stage of the lifecycle and the dependability requirements to be met for hardware design, the metrics (SPFM, LFM...) to target via hardware FMEA methods (hwFMEA, FMEDA or eFMEA) and Fault Tree Analysis, safe design techniques up to hardware validation.
