Abstract

Complex SOC's developed in VDSMtechnologies require adequate solutions to diagnose andanalyze yield losses. This paper focuses on the diagnosisof logic circuits embedded in SOCs. The core instrumentleveraged is ATPG used during test vectors generation andanalysis of failures. This work emphasizes the resultsobtained in systematically applying ATPG diagnosis onfailures detected in the manufacturing test floor. Details ondiagnosis flow and ATE data collection are given.Experimental results are provided.
