Design Check in OrCAD
Today, we'll walk through the design check process in OrCAD. This step is crucial after completing the initial wiring of your PCB layout. The main goal is to ensure that all networks are properly connected and that there are no errors or leftovers that could affect the functionality of the board.
First, you should check for any un-routed networks. To do this, go to **Tools > Reports**. From there, double-click on the **Unplaced Components Report** to review which components might not have been placed correctly. Then, click on **Display Report** to view the details.
After that, generate a report by clicking **Report**. This will show you all the unrouted networks, allowing you to complete the routing as needed. You can also use this report to identify any missing connections or issues in the design.
Next, you should look for excess or unnecessary elements such as dangling lines, vias, or antennas. Again, go to **Tools > Reports**, and select the **Dangling Lines, Via, and Antenna Report**. This will list all the extra elements in your design.
Once the report is generated, you can see a detailed view of these issues. Use the coordinates provided in the report to locate the specific areas on your PCB where these problems exist. This makes it easier to fix them directly on the board.
Additionally, you can use **Tools > Quick Reports** to quickly access and generate various reports. Click on the desired report to view its content, then make necessary improvements based on the findings. Don't forget to save the report once you're done for future reference.
This entire process ensures that your design is clean, accurate, and ready for manufacturing. By following these steps, you can significantly reduce the risk of errors and improve the overall quality of your PCB layout.
