Yield-preferred via insertion based on novel geotopological technology

摘要: Yield-preferred via insertion is an effective method to reduce the yield loss caused by failures. The existing methods apply redundant-cut vias in metal layers are not efficient nor adequate. In this paper, we present and yield-preferred based on a novel geotopological layout platform, GEOTOP. Our chooses most yield-favored candidate insert it into without causing any design rule violations. Experiments with real industry designs show that our can achieve very high rate of increasing die size within acceptable running time.
