The Clock-Domain-Crossing Conundrum

– Jerry Cox The Clock-Domain-Crossing conundrum is this:  Where is the evidence of Clock-Domain-Crossing (CDC) failures that have occurred during a product’s service life? We know there have been products that have had CDC failures during test and been re-spun,...

A Public Synchronizer

GET THE PUBLIC SYNCHRONIZER NOW You might ask yourself “Why would anyone want to have a public synchronizer available to download?” Usually designers just grab a flip-flop from his or her company’s or a standard cell vendor’s library. However, are these handy...

Measuring Metastability

Measuring metastability is just 50 years old this year. In 1965 my colleague Tom Chaney took a sampling ‘scope picture of an ECL flip-flop going metastable. S. Lubkin had made mention of the phenomenon over a decade before that, but at that time most engineers were...

When is a Million-Year MTBF Too Short?

Jerry Cox The reliability metric, Mean Time Between Failures (MTBF), is often misunderstood. Use of an MTBF metric generally assumes a random failure process, one that is very infrequent and has no memory of past failures. Such failure modes can occur in...

Synchronizer Reliability Metrics

Jerry Cox As an example of the need for real-world reliability metrics, consider a modern automobile. We can already buy a car with parking assistance, collision avoidance, autonomous braking and adaptive cruise control features. These new features depend on video...
