Bridging the Testing Speed Gap: Design for Delay Testability

Abstract

The economic testing of high-speed digital ICs is becoming increasingly problematic. Even advanced, expensive testers are not always capable of testing these ICs because of their high-speed limitations. This paper focuses on a design for delay testability technique such that high-speed ICs can be tested using inexpensive, low-speed ATE. Also extensions for possible full BIST of delay faults are addresse
