    摘要: Disclosed is a method and system for processing the tasks performed by an IC layout processing tool in parallel. In some approaches, the IC layout is divided into a plurality of layout portions and one or more of the layout portions are processed in parallel, where geometric select operations are performed in which data for different layout portions may be shared between different processing entities. One approach includes the following actions: select phase one operation for performing initial select actions within layout portions; distributed regioning action for local regioning; distributed regioning action for global regioning and binary select; count select aggregation for count-based select operations; and select phase two operations for combining results of selecting of internal shapes and interface shapes.

    摘要: In random defect yield simulation, a specific defect size interacts with a specific physical design and has a calculated probability of failure associated with it. The failure model is in terms of probability of failure. It provides a solution to the random defect yield simulation problem of chips with a built-in redundancy scheme. The solution first defines the independent failure modes of the chip with a built-in redundancy scheme and efficiently models each mode. Then, it may accumulate the respective probability of failures according to the chip's architecture.

    摘要: The present invention presents a hybrid approach for manufacturability analysis that integrates both a rules-based approach and a models-based approach. For example, a rules-based analysis can be used to optimize the performance of a model-based analysis. The rules analysis can be used to identify specific areas of a layout that can then be analyzed in detail using models. This approach provides numerous advantages. It allows the models-based analysis tool to concentrate upon portions of the layout that requires greater attention and allocate fewer resources towards the areas less critical to the yield.
