Applications of Constraint Management Used in various PCB designs, especially those with complex requirements or high-speed applications. Below are some appli- cations where constraint management is commonly applied: f High-Speed PCBs: Where signal integrity and timing are critical. f Complex Multilayer Boards: Where managing multiple constraints is essential for performance and manufacturability. f Consumer Electronics: Ensures reliable operation in compact and thermally challenging environments. f Automotive and Aerospace: Where reliability and adherence to stringent standards are crucial. Now that we understand the impact and importance of constraint management in PCBs, let's discuss the types of constraints and how the Cadence ® OrCAD ® X Platform organizes constraints in a way that is easy and flexible. Finding the Constraint Manager (CM) In OrCAD X Presto PCB Editor, select Tools - Constraint Manager to open the constraint manager (CM). You will see the window shown in the image below. The constraint manager has a lot of rows and columns that are essentially spreadsheet files placed into various folders called 'worksheets'. Don't worry about the detailed structure for now, as we will understand sheets, rows, cells and so on throughout the guide. 4 www.cadence.com OrCAD X Constraint Management Guide
