Design <strong>for</strong> Testability (DFT)• A fault is testable if there exists a well-specifiedprocedure to expose it, which can beimplemented with a reasonable cost using currenttechnologies− A circuit is testable with respect to a fault set wheneach and every fault in this set is testable• The term DFT refers to a class of designmethodologies which put constraints on thedesign process to make test generation anddiagnosis easier• Testability = controllability + observabilitym01intro7.02 Cheng-Wen Wu, NTHU 22
