However, the extensive use of vias and buffers in a deep-submicron circuit and the unpredictable order relation among threshold voltages at the fanout branches of a gate have not been fully addressed by conventional per-test X-fault diagnosis. To take these factors into consideration, this paper proposes an improved per-test X-fault diagnosis method, featuring (1) an extended X-fault model to handle vias and buffers and (2) the use of occurrence probabilities of logic behaviors for a physical defect to handle the unpredictable relation among threshold voltages. Experimental results show the effectiveness of the proposed method.}, pages = {667--674}, title = {A Novel Per-Test Fault Diagnosis Method Based On the Extended X-Fault Model for Deep-Submicron LSI Circuits}, volume = {E91.D}, year = {2008}, yomi = {ミヤセ, コウヘイ and オン, ギョウセイ and カジハラ, セイジ} }
