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 ...
Why isolated flows negatively impact design schedule and PPA. Benefits of unified DFT, synthesis, and physical design flows. Physical implementation optimization methods for test compression and scan ...
Some new design-for-test (DFT) technologies are difficult, expensive, or risky to implement but offer significant benefits. Other technologies are easy to implement but offer minor improvements. The ...
The fundamental challenges of IC test have been the same for a long time. At the heart of all test strategies is controllability and observability. First, control the state of the chip with known test ...
