As shown in previous parts of the guide, you can create a net class by highlighting the nets you want in that class, then right clicking any of the highlighted nets, then choosing Create – Net Class, naming that class then clicking OK. 7. That has been repeated to create the net classes shown below. As shown in the first part of this document, Net Classes are often not enough to organize all our nets. Net Classes organize nets by physical and electrical properties, but oftentimes we also need to organize nets by function, regardless of their properties. Let's look at the Net Groups defined in this project. Define Net Groups We also need to define our net groups for the following (e.g. for HDMI, USB, DDR2, DDR3, or any important functional groups etc.) Within the Constraint Manager in OrCAD X Capture: 8. Go back to the Electrical > Routing > Wiring worksheet. 9. You will see all the nets in your design, along with their organizational labels (NCls, DPr, etc.) 6 www.cadence.com OrCAD X Constraint Management Guide
