OrCAD X Library Footprint Path and Information | Cadence

Key Takeaways

• Properly configuring library footprint paths in OrCAD X ensures accurate netlisting

• The footprint editor in OrCAD X allows direct modification and updating of footprints

• OrCAD X includes a footprint generator to automate the creation of industry-standard footprint packages

Configuring an OrCAD X library footprint path makes it easy to ensure that schematic symbols link properly to their corresponding PCB footprints. In OrCAD X, footprint libraries are stored in designated directories, and configuring these paths correctly helps prevent errors during netlisting and layout. Understanding how to manage, edit, and automate footprint generation within OrCAD X can streamline your PCB design workflow and improve accuracy. This guide will discuss it all. 

Configuring OrCAD X Library Footprint Paths 

One of the critical steps in managing your PCB designs is ensuring that your schematic symbols correctly link to the corresponding PCB footprints. In OrCAD X, footprint libraries are stored in specific directories – for example, many systems use paths such as:
C:\Cadence\SPB_<version>\share\pcb\pcb_lib\symbols.

When you add a schematic symbol to your design, it’s essential to set the correct footprint path so that during netlisting the tool locates the right physical representation. 

Managing and Editing Footprint Libraries in OrCAD X Workflows

OrCAD X not only allows you to configure library paths but also offers workflows for editing footprint data. 

1. Right-click the component in your layout and select “Edit Footprint”.

2.  If the footprint exists in your library, it opens automatically; if not, you’ll be prompted to export it to your working directory.

3. The Footprint Editor window opens alongside your original layout database.

4. Make your edits (e.g., move pins, add pins, modify pad stacks) as needed.

5. When finished, choose Exit from the file menu and save your changes.

6. Back in the layout editor, you’ll be prompted to apply the updates—confirm to refresh all instances of that footprint in your design.

How the Component Information System (CIS) in OrCAD X Aids in Library Footprint Organization

CIS integrates a centralized part database directly into the OrCAD X Capture environment, enabling you to instantly review symbols, footprints, parametric details, and supply chain information—all in one place.

OrCAD X library footprint paths are integrated into the Component Information System (CIS), ensuring that schematic symbols are automatically linked to their correct PCB footprints. This centralized approach simplifies footprint management across your design environment by allowing direct review and updates through the integrated part database.

OrCAD X Template Driven Footprint Creation

Creating accurate PCB footprints is important, especially if you are using uncommon components. OrCAD X significantly simplifies this process by automating the creation of hundreds of industry-standard footprint packages.  Designers can select the type of footprint they need, fill in the specific parameters tailored to their design requirements, and then specify the relevant IPC class to ensure compliance. Once these inputs are provided, the software generates a complete footprint that includes all essential elements—such as keepouts, pins, and solder masks—while also producing an integrated 3D model of the package.

This streamlined, automated process not only saves valuable design time but also enhances accuracy and manufacturability across the entire PCB design workflow.

Locating and Browsing Included PCB Footprint Libraries in OrCAD X

Many designs require manufacturer-specific or standardized footprints (e.g., SOIC, DIP). OrCAD X includes pre-built footprint libraries to jump-start your design process.

New Footprint Library Capabilities in OrCAD X 24.1 

OrCAD X introduces a powerful footprint generator accessible under File > New Template Based Footprint, offering a library of ITC-based footprint templates. The generator provides detailed parametric controls for creating precise PCB footprints across multiple component categories.
