Design-For-Test The Smart Way: dFT With A "Big T" And A "Little d"

Design-for-test, or DFT, should facilitate high-quality test, not change the design. Test techniques and strategies need to supply a high-quality test that screens out defective devices, avoiding ...

Simulation Mismatches Can Foul Up Test-Pattern Verification

Design for testability (DFT) works to make a circuit more testable to ensure that it was manufactured correctly. Alfred Crouch explains the purpose of DFT in his book, Design-For-Test for Digital ICs ...
