Design for manufacturability (DFM) is inevitable because of the formidable challenges encountered in nano-scale integrated circuit (IC) manufacturing. Unfortunately, it is difficult for designers to understand the cost-benefit tradeoff when tuning their design through DFM to achieve better manufacturability. This work attempts to assist the designer in this(More)
h A VARIETY OF yield-learning techniques are essential since no single approach can effectively find every manufacturing perturbation that can lead to yield loss. Test structures, for example, can range from being simple in nature (combs and serpentine structures for measuring defect-density and size distributions) to more complex, active structures that(More)
Traditional software-based diagnosis of failing chips typically identifies several lines where the failure is believed to reside. However, these lines can span across multiple layers and can be very long in length. This makes physical failure analysis difficult. In contrast, there are emerging diagnosis techniques that identify both the faulty lines as well(More)
Logic-level simulation has been the de facto method for simulating defect/faulty behavior for various testing tasks since it offers a good tradeoff between accuracy and speed. Unfortunately, by abstracting defect behavior to the logic level (i.e., a fault model), it also discards important information that inevitably results in inaccuracies. This paper(More)
