摘要： Aspects of the invention relate to techniques for generating encrypted profiles for layout features. According to various implementations of the invention, a layout feature is partitioned into subdomains. The subdomains are associated with boundary nodes and internal nodes. Based on layout design and process profile data for the layout feature, a first electric parameter relationship is determined for the boundary nodes and the internal nodes. An encrypted profile for the layout feature is then generated by converting the first electric parameter relationship into a second electric parameter relationship involving the boundary nodes. The encrypted profile may be used for extracting parasitic parameters associated with the layout feature.

摘要： A system and method include receiving, by a processing device of a manufacturing execution system (MES), a target profile associated with products, wherein the target profile comprises an identifier of a block of steps in a process to make the products and a target work-in-progress (WIP) value representing a target number of parts waiting to be processed by a group of machines used in the block of steps to make the products, identifying a move list or an assignment list that, when issued, causes the group of machines to operate to maintain a number of parts waiting for processing to match the target WIP value of the target profile.
