摘要： The invention provides a method of modifying a hierarchical integrated circuit layout wherein the locations of hierarchical layout elements are represented with variables and formulae using these variables, which produces a formula-based hierarchical layout. These variables are constrained to be integers. The invention provides for a method for guiding the modification of the layout through an objective function defined on the same variables as the formula-based hierarchical layout. The invention simplifies the formula-based hierarchical layout by substituting constants for some of the variables, such that each of the formulae are reduced to expressions involving no more than two remaining variables. This produces a simplified layout equation and a simplified objective function. This also produces a partial solution to the hierarchical layout modification made up of the values selected for the constants.
摘要翻译：本发明提供了一种修改分层集成电路布局的方法，其中使用这些变量的变量和公式表示分层布局元素的位置，这产生基于公式的分层布局。这些变量被约束为整数。本发明提供了一种用于通过与基于公式的分层布局相同的变量定义的目标函数来引导布局的修改的方法。本发明通过将常数替换为一些变量来简化基于公式的分层布局，使得每个公式被减少到涉及不超过两个剩余变量的表达式。这产生了简化的布局方程和简化的目标函数。这也产生了对由常量选择的值组成的分层布局修改的部分解决方案。

摘要： Systems and methods for determining a course of action in a real-time case based on analysis of trend data in historical cases. The system includes an historical initial data interface; an historical outcome interface; an historical response interface; an historical database; a trend analyzer; and a trend analysis interface. The method includes obtaining historical initial data for more than one historical case; associating an historical response and an historical outcome with each of the historical cases; storing the historical initial data and the associated historical responses and outcomes for each of the historical cases; identifying trends between the historical initial data and the associated historical responses and outcomes in the historical cases; obtaining initial data for the real-time case; and determining a course of action in the real-time case based on the identified trends from historical cases having similar historical initial data to the initial data in the real-time case.
