Handling the pin overhead problem of DFTs for high-quality and at-speed tests.

The pin overhead problem of nonscan design for testability (DFT) and built-in self-test design has been an unsolved problem for a long time. A new algorithm is proposed to connect extra pins of control test points with primary inputs. An economical test point structure is introduced, in which only o...
