14. Those rules will then be transferred to your PCB environment so that the layout engineer can start on the right foot, so to speak with their PCB design. 15. Notice some differences in the Electrical Constraint Set where you can define Noise margin in the Electrical Constraint Set > Reflection/Edge Distortions worksheet. 16. When done with your constraint setups, use the menu in Capture to select PCB - Update Layout… to move constraints to OrCAD X Presto PCB Editor. 17. Verify transferred constraints in the PCB Constraint Manager. Reason for Capture Constraint Manager: Early constraint definition in the schematic phase allows for proactive design decisions, reducing iterations and improving overall design quality. Impact: Streamlines the design process, ensures consistency between schematic and PCB, and facilitates informed decisions on stackup and material selection based on electrical requirements. This approach emphasizes "real engineering design powered by early constraints," moving away from the "wing it, review it, iterate" cycle and potentially reducing the number of board respins required. Importing and Exporting Constraints In this section you learn how to export constraints, which features to select, the impact they have on a design for other engineers and how you can use them in future projects immediately. Here are some steps for exporting and importing constraint manager files in OrCAD X, along with the benefits: f Implementation in Constraint Manager: ɢ Create standardized constraint sets for common design elements as mentioned in the previous section ɢ Select/Highlight the Constraints you want to export, as shown below. f Use the "Import/Export" feature to save and load constraint sets ɢ In the Constraint manager go to File - Export - Constraints… 6 www.cadence.com OrCAD X Constraint Management Guide
