    • A method of polygonal area design rule correction for use in an electronic design automation tool for governing integrated circuit (IC) design layouts using one-dimensional (1-D) optimization, with steps of analyzing IC design layout data to identify violating polygons, partitioning violating polygons into rectangles in a direction of optimization, formulating an area constraint for each violating polygon to formulate a global linear programming (LP) problem that includes each constraint for each violating polygon and solving the global LP problem to obtain a real-valued solution. A next LP problem is created for each area constraint, and solved. The creating a next and solving the next LP problem and solving are repeated until the last “next LP problem” is solved using constraints and objectives representing sums or differences of no more than two optimization variables.
    • 一种多边形区域设计规则校正方法,用于电子设计自动化工具,用于使用一维(1-D)优化来管理集成电路(IC)设计布局,并分析IC设计布局数据以识别违反多边形,划分 在优化方向上将多边形侵入矩形,为每个违规多边形制定面积约束以制定全局线性规划(LP)问题,其包括每个违反多边形的每个约束,并解决全局LP问题以获得实值解。 为每个区域约束创建下一个LP问题,并解决。 重复创建下一个LP并解决下一个LP问题和解决问题,直到最后的“下一个LP问题”使用表示不超过两个优化变量的和或差的约束和目标来解决。
