Recorded Webinars: Predicting “Useful Life” with an FMEDA
Failure rate data for many different devices has shown that a device failure rate changes during the operating time interval. The failure rate would follow what has become known as the “Bathtub Curve.” Failure rates can be approximated as a constant value during the flat bottom of the Bathtub Curve for a time period known as Useful Life. At some point in time, the failure rate increases, often rapidly. This marks the end of the Useful Life time period. In Functional Safety (FuSa), one critical performance metric, called PFDavg (the average probability that a safety protection function will not work when needed) is calculated. Failure rates are an input to this calculation and are only valid during the Useful Life. Therefore, Useful Life is required for FuSa. An FMEDA can be used to predict this important metric. This webinar explains the Reliability Engineering background and the method used in FMEDA.
Recorded Webinars: Using a Spreadsheet to do FMEDA
An FMEDA is a failure metric analysis method used primarily to predict failure rates of embedded controllers, sensors, and final elements. When the FMEDA method was invented in the late 1980s, a spreadsheet was the obvious choice for implementation. Even with the proliferation of bespoke FMEDA tools, a spreadsheet can still be used today, especially for simple mechanical and electrical devices. This webinar shows examples of spreadsheets in use, explains how to set up the calculations used in the spreadsheet and gives a detailed example of an FMEDA done using a spreadsheet.

Recorded Webinars: What is an FMEDA?
FMEDA is an acronym for Failure Mode, Effects and Diagnostic Analysis. It is a method developed to predict quantitative failures for each failure mode of a device considering the impact of automatic diagnostics which have become the most common way to achieve high availability and functional safety in smart systems. This webinar provides an introduction to this popular method including FMEDA inputs, process, and results achieved.
Blog Entry: What is a FMEDA?
In the 1980’s, there was a raging debate in the functional safety committee about redundancy versus diagnostics. Some said functional safety could only be achieved with redundant systems. This was strongly supported by Triple Modular Redundant (2oo3) safety PLC vendors. Others argued that diagnostics would be an equal or better…

Recorded Webinars: exida’s Pathway to Safe Machine Learning (ML)
Machine Learning (ML) and Artificial Intelligence (AI) are being used more and more in products. There is interest in using ML in safety critical systems, but most existing safety standards were not written with ML in mind.
As the functional safety community waits for guidance from standards on using ML in safety critical tasks, exida is developing a ML assessment scheme.
This webinar will provide an overview of exida’s ML assessment scheme and exida’s planned ML service offerings.
- Assessment against rigorous design process requirements, and
- ML statistical performance analysis, based on Dr. O’Brien’s PhD thesis.

Recorded Webinars: Optimizing the Development Process with OEMx
New product development procedures are created to optimize tradeoffs including time to market, design quality, and schedule. These tradeoffs are tough, even in designs for critical systems where design quality is required for functional safety and cybersecurity compliance. New methods and new tools can make these tradeoffs easier. This webinar describes an example development process and show how the OEMx tool set is used to improve design quality and reduce engineering time.
