Signature based diagnosis for logic BIST
2007
This paper presents a new approach for performing logic BIST diagnosis exclusively using MISR signatures. Unlike conventional logic BIST diagnosis approaches which require either huge test time or complicated logic BIST design and ATE flow, signature based diagnosis does not require dynamically changing MISR operations for each failing device. Our experimental data shows that signature based diagnosis can achieve similar diagnosis resolution with manageable diagnosis run time while eliminating most of the complexity associated with the traditional approach to logic BIST diagnostics.
