Abstract
Complex SOC's developed in VDSM technologies require adequate solutions to diagnose and analyze yield losses. This paper focuses on the diagnosis of logic circuits embedded in SOCs. The core instrument leveraged is ATPG used during test vectors generation and analysis of failures. This work emphasizes the results obtained in systematically applying ATPG diagnosis on failures detected in the manufacturing test floor. Details on diagnosis flow and ATE data collection are given. Experimental results are provided.
