Justifying DFT with a Hierarchical Top-Down Cost-Benefit Model
Scott Davidson · 2008
How can we justify system level DFT? We must show that it has a positive return on investment (ROI). Existing test ROI models are manufacturing centric, do not account for the disaggregation of the product realization process, and are often focused on a specific DFT method. We propose a new, top-down, hierarchical ROI model, which starts with potential benefits and can handle entire systems more effectively than current models.
