Conventional stuck-at fault model is no longer sufficient to deal with the problems of nanometer geometries in modern Large Scale Integrated Circuits (LSIs). Test and diagnosis for transistor defects are required. In this paper we propose a fault dia

Shorts and opens are two major kind of defects that are most likely to occur in Very Large Scale Integrated Circuits. In modern Integrated Circuit devices these defects must be considered not only at gate-level but also at transistor level. In this p

Physical defects that are not covered by stuck-at fault or bridging fault model are increasing in LSI circuits designed and manufactured in modern Deep Sub-Micron (DSM) technologies. Therefore, it is necessary to target non-stuck-at and non-bridging

This paper presents methods for detecting transistor short faults using logic level fault simulation and test generation. The paper considers two types of transistor level faults, namely strong shorts and weak shorts, which were introduced in our pre

With the increasing complexity of LSI, Built-In Self Test (BIST) is a promising technique for production testing. We herein propose a method for diagnosing multiple stuck-at faults based on the compressed responses from BIST. We refer to fault diagno

In general, we do not know which fault model can explain the cause of the faulty values at the primary outputs in a circuit under test before starting diagnosis. Moreover, under Built-In Self Test (BIST) environment, it is difficult to know which pri

In order to reduce the test cost, built-in self test (BIST) is widely used. One of the serious problems of BIST is that the compacted signature in BIST has very little information for fault diagnosis. Especially, it is difficult to determine which te

Recently there are various requirements for LSI testing, such as test compaction, test compression, low power dissipation or increase of defect coverage. If test sequences contain lots of don't cares (Xs), then their flexibility can be used to meet t

We describe a method of identifying a set of target crosstalk faults which may need to be tested in synchronous sequential circuits. Our method classifies the pairs of aggressor and victim lines, using topological and timing information, to deduce a
