Adaptive testing: Conquering process variations

Abstract

Increasing process variations result in increasing statistical diversity in manufactured devices. Test plans that are developed without this diversity in mind are bound to result in poor test quality/yield and/or long test times. Adaptive testing is a general term that is used to tailor the test strategy to accommodate a wide range of variation in the statistical characteristics of manufactured devices. In this paper, we provide a review of the key works in both digital and analog domains.
