Safety Integrity Level (SIL)

Safety Integrity Level (SIL)

At its core, Safety Integrity Level (SIL) is about managing residual risk. But what exactly does SIL mean, and how is a system designed to meet the appropriate SIL level? Let’s break it down with a simple example.👇🏼 Jargon Jive

Diagnostic Coverage Estimation

Diagnostic Coverage Estimation

Diagnostic Coverage (DC) measures the fraction of dangerous detected failures in a system. But in practice, predicting all possible manners a function can fail, and developing a diagnostic function that covers them all is challenging. So, how do we go about it? 🤔Join...

Common Cause Failure (CCF)

Common Cause Failure (CCF)

Common Cause Failures (CCFs) are a critical functional safety concept that can render even redundancy measures ineffective. But what are they, how do they occur, and how can they be avoided? 🤔 Dive in to learn more with a simple example.👇🏼 Jargon Jive
