This walk-through demonstrates several techniques for connecting components in OrCAD Capture version 17.4-2021. After you complete this topic, you will be able to:
- Connect components to wires
- Select and move groups of wired components
- Connect a bus to components and nets
To follow along with this tutorial, continue with the design you completed for Capture Walk-through 3 or use the included design file, CAPTURE TUTORIAL 4_WIRING.DSN under ‘materials’ tab.
