Part 2 - Standard Constraints Welcome to the second part of this Constraint Management Guide. This section covers the common constraints you will need to set for most printed circuit boards (PCBs). Below is a general list of the format we will be following: 1. Purpose: Briefly states the purpose of the constraint. Example: Ensures minimum spacing to prevent electrical interference. 2. Visual Aid: Relevant images or screenshots to illustrate the process. Example: Diagram of Constraint Manager with highlighted options. 3. Steps: Outlines the steps to implement the constraint in OrCAD X Presto PCB Editor. Example: Open Constraint Manager > Select Category > Set Parameters > Apply. 4. Reason: Explains why this constraint is important. Example: Critical for maintaining signal integrity in high-speed designs. 5. Impact: Describe the impact of implementing this constraint. Example: Reduces risk of signal crosstalk, improving overall design reliability. For more details on constraints, please refer to online documentation and training. Physical and Spacing Constraints Trace Width: Minimum and Maximum Width for Signal And Power Traces. Top view of PCB traces with different widths Purpose: Defines minimum and maximum trace widths for signal and power traces. Steps: 1. Open Constraint Manager. Select Physical > Physical Constraint Set > All Layers > Create a Constraint Set if necessary. 3 www.cadence.com OrCAD X Constraint Management Guide
