FMEDAx Auto

Meeting ISO 26262 Standards

Optimizing Diagnostic Design Tradeoffs

exSILentia Cyber

Do you want failure rate and failure mode data predictions for ISO 26262 compliance?

Does your FMEDA failure database have all components needed?  With all known failure modes?

FMEDAx Auto provides an integrated the engineering tool needed for effective, integrated design analysis.

Failure Rate Prediction

Failure Modes Effects and Diagnostics Analysis (FMEDA) is a failure rate prediction technique invented by engineers at exida that uses component failure rates chosen per a given design strength profile in combination with an operational profile which specifies an application and environment. 

The FMEDA technique is performed on a specific device (e.g., LIDAR sensors, motor controllers etc.) specified down to the manufacturer and series/model.   Variables that must be considered in the analysis include:

  • the parts used to execute the design, 
  • the design margins, 
  • any automatic diagnostics, 
  • the specific application usage and 
  • the environment in which the device will be deployed. 

The FMEDAx Auto tool user enters information for the specific design based on product schematics along with expert knowledge on the potential impact of expected failure modes and how they would be handled in the specific system under evaluation. This analysis is a part of the typical high-quality product design certification process for a product certified to ISO 26262 for a particular ASIL. 

The FMEDAx Auto tool was created by the inventors of the FMEDA technique and incorporates the knowledge developed over decades of use.  The FMEDAx tool comes with an electronic database specified for automotive operational profiles. 

Electrical / Mechanical Component Database (EMCD) Auto

  • Provides all the information needed for accurate failure rate/mode predictions. Unlike other database sources, the EMCD™ database contains failure rates, failure modes and failure mode distributions for both the engine compartment and the passenger compartment. Engineers performing FMEDA work will no longer have to spend hours searching the internet for failure modes / distributions, etc.
  • Has a stronger variety and quantity of components than any other component database. Combine this with the EMCD™ database service, where licensed customers may request new part creation based on exida data. This will save many engineering hours. 
  • Provides failure rate / failure mode data sets for multiple application conditions and operating profiles. 
  • Is updated one or more times per year with new components and/or new failure modes/Failure mode distributions.  This feature allows Engineers to stay up to date with the latest technology.
