Linking FMEA, FMEDA, and FTA for Safety Analysis and Hardware Metrics for Functional Safety

SPONSORED BY:


FMEAs traditionally have only incorporated single-point faults. This 30-minute Webinar examines a groundbreaking methodology used to conduct safety analysis and hardware metrics for functional safety using linked FMEA, FMEDA, and FTAs. It shows how functional safety FMEA can include both single- and multi-point faults and incorporate safety mechanisms as preventive controls.

As the FMEA is filled out, the FMEDA will be populated, providing consistency between the FMEDA and FMEA techniques. The FMEA of the hardware is at the hardware system level, while the FMEDA is at the component level, and the failure modes of the FMEDA are component failure modes. If the FMEA is completed using the AIAG-VDA FMEA, where the higher level, focus level, and lower levels are related, and there is a cause-and-effect relationship between the failure modes, then the FTA can also be developed from the FMEA. In this way, the FMEA, FMEDA, and FTA are linked documents, and the FMEDA and FTA provide the single-point fault, multi-point fault, and the "Probabilistic Metric for random Hardware Failures" (PMHF) metrics in a consistent manner.

An audience Q&A follows the technical presentation.
