We present a persistent diagnostic technique for unstable defects, such as open defects or delay defects. A new "segment model" diagnosis for the completely open defects will be discussed. Here, we not only focus on the behavior of the principal offender, but also the behavior of the accomplices which cause the unstable behavior of the defect. In this paper, a technique using the layout information for an open faul diagnosis, and a testing method for the delay fault will be discussed. Some experimental results of actual chips will be shown.
