Variables Complicate Safety-Critical Device Verification 

July 1st, 2020 – By Ann Steffora Mutschler

SE: Where does the industry stand with the task of verifying safety-critical devices today?

Kurt Shuler responds, “At the chip level we still have a situation where the verification people and methodologies are separate from the functional safety people and methodologies. This results in some overlap and rework. As tools and data interchange standards (like IEEE P2851 being led by both IEEE and Accellera) mature, we’ll be able to have more automation where functional safety validation through fault injection can be executed as part of regular verification processes. This will help everyone in the industry have more confidence that products don’t regress in diagnostic coverage as new versions are developed and will provide integrators/users of safety-critical systems to more easily perform fault injection validation of safety mechanisms if they desire.”
