    • User designs are assigned to a category for each design goal associated with the user design. Each category represents the difficulty of satisfying a design goal. Optimization phases are tailored to different combinations of categories and are selected according to the categories assigned to the user design. A ranking of the relative difficulty of the design goals is determined from the categories associated with the user design. Parameters of an optimization phase can be modified in accordance with this ranking to focus optimization efforts on specific design goals. The parameters may be weights of a cost function used by the optimization phase to evaluate alternative configurations of the user design. The user design can be re-classified into an additional category if the results of the optimization phase do not satisfy design goals, and additional optimization phases are selected based on this re-classification to further optimize the user design.
    • 用户设计被分配到与用户设计相关联的每个设计目标的类别。 每个类别代表满足设计目标的难度。 优化阶段根据类别的不同组合进行调整,并根据分配给用户设计的类别进行选择。 根据与用户设计相关的类别确定设计目标相对难度的排名。 优化阶段的参数可以根据这个排名进行修改,将优化工作集中在具体的设计目标上。 参数可以是优化阶段用于评估用户设计的替代配置的成本函数的权重。 如果优化阶段的结果不满足设计目标,则可以将用户设计重新分类为另外的类别,并且基于该重新分类来选择额外的优化阶段以进一步优化用户设计。
