DFFT design for functional testability

Creating functional tests that work on an ATE has always been a significant challenge [I]. This paper identifies the fundamental mechanisms for functional test failures of an SOC on an ATE. Taking these mechanisms into account during the design process of a chip can substantially reduce the efforts needed to make functional tests work. We call this process design for functional testability (DFFT).
