Uneven Circuit Aging Becoming A Bigger Problem
It is becoming easier to fix the problem as more variables are introduced.
As engineers look for ways to increase reliability and maintain functionality of chips over their lifetime, circuit aging has become a major design challenge.
In data centers and cars, a failure of a chip could cause downtime or even injury. The need for reliability is also becoming more important for mobile and consumer electronics. These devices are used in applications like in-home navigation or health monitoring, and the costs of these devices have been rising steadily. It is also important to consider the different variations of foundries’ models, the different uses that can stress different components, as well as the different thermal and power profiles. This makes it difficult to predict the behavior of a chip over time.
