The Design-for-Test (DFT) methodology is a strong driving force in the cost-effective testing of large-volume commodity items with very short life cycles, like system-on-chip (SoC) devices. It will ...

When existing advanced 2D designs already push the limits of design-for-test (DFT) tools, what hope do developers have of managing DFT for 3D devices? Can anyone afford the tool run time, on-chip area ...

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 ...

Over the last few years, design-for-test (DFT) chip-testing techniques such as internal scan (ISCAN), automatic test-pattern generation (ATPG), built-in self-test (BIST), and boundary scan (BSCAN) ...

Improved testability, coupled with more tests at more insertion points, are emerging as key strategies for creating reliable, heterogeneous 2.5D and 3D designs with sufficient yield. “With chiplets, ...
