Also, below you can see where the DDR regions we create will apply to the design. Note: Physical region definition is for physical attributes only. We would need to create a region for spacing rules as well. TIP: Recall that even though we have net classes and groups, we still need specific rules in certain parts of the PCB across different layers (or all) for that area sometimes so we can deviate from the default, class, and group net routing and spacing rules. Please refer to our complete section on Constraint Regions in a previous part of this guide. 9 www.cadence.com OrCAD X Constraint Management Guide
