摘要： Features are provided for graphically representing constraints on design objects in an Electronic Design Automation tool. A particular constraint on one or more circuit objects is displayed as a highlighted region that extends to each visible circuit object to which the constraint applies. Attributes of the highlighted region, such as density and thickness, may proportionally represent attributes of the constraint, such as a strength or distance specified by the constraint. The highlighted region is superimposed on or around circuit objects. The highlighted region may be a halo, which is a partially transparent region filled with a color. Multiple regions that represent the same type of constraint or relationship are connected by line segments, providing the ability to visualize groups of constrained objects, including groups that span levels of a hierarchical design. Intersecting highlighted regions are blended together using techniques such as alpha blending.

摘要： A method, mechanism, and system for determining an effective resistance for a network of resistors, irrespective of the number of terminals is provided. An aspect of an approach relates to the reduction of any network of resistors to a single resistance value. Another aspect of an approach relates to the application of a power loss calculation to determine the effective resistance. Yet another aspect of an approach relates to the integration of the method/mechanism with an analog simulator.
摘要翻译：提供了用于确定电阻网络的有效电阻的方法，机构和系统，而不考虑端子数量。方法的一个方面涉及将电阻器的任何网络减少到单个电阻值。方法的另一方面涉及功率损耗计算的应用以确定有效电阻。方法的另一方面涉及方法/机构与模拟仿真器的集成。
