Abstract :
Nowadays, with the increasing complexity of new VLSI circuits, laser stimulation or emission techniques and scan-based ATPG diagnostic reach their limits in functional logic failure. To overcome these limitations, a new methodology has been established. This methodology, presented in this paper, combines the advantages of both approaches in order to improve accuracy of fault isolation and defect localization.
