EDA File Format Compatibility Issues with Nvidia Jetson Orin Nano Dev Board

Issue Overview

Users are experiencing difficulties in obtaining EDA (Electronic Design Automation) files compatible with PCAD for designing custom carrier boards for the Nvidia Jetson Orin Nano Dev board. The primary symptoms include:

• Incompatibility of EDA Files: All available EDA files are in OrCAD or Allegro formats, which do not meet the requirements of users working with PCAD.

• Context of the Issue: This problem arises during the design phase of custom hardware intended for agricultural AI applications, specifically when users attempt to integrate the Jetson Nano into their projects.

• Hardware Specifications: The issue pertains to the Jetson Orin Nano Dev board and its associated components, particularly the SODIMM connector necessary for custom carrier board designs.

• Frequency of Occurrence: The problem appears to be consistent among users who require PCAD formats, as indicated by multiple inquiries on forums.

• Impact on User Experience: This limitation can significantly hinder development timelines and increase frustrations for engineers needing to create compatible designs.

Possible Causes

The following potential causes have been identified for the issue:

• File Format Limitations: The EDA files are exclusively available in OrCAD and Allegro formats, which may not be convertible to PCAD without additional tools or manual intervention.

• Lack of Support from Manufacturers: The manufacturers may not provide EDA files in PCAD format due to limited demand or resource allocation.

• User Misconfiguration: Users may not be aware of available tools or services that could assist in converting EDA files from one format to another.

Troubleshooting Steps, Solutions & Fixes

To address the compatibility issues with EDA files for the Nvidia Jetson Orin Nano Dev board, users can follow these troubleshooting steps and solutions:

1. Explore Conversion Tools:

   • Research and utilize file conversion tools that can convert OrCAD or Allegro files to PCAD format. Some users have found success using online conversion services.

2. Utilize SnapEDA:

   • Visit SnapEDA (snapeda.com) to download schematic symbols, PCB footprints, and 3D models for components like the SODIMM connector. This site offers exports to various formats, which might include options compatible with PCAD.

3. Contact Manufacturer Support:

   • Reach out directly to Nvidia or authorized distributors to inquire about the availability of PCAD-compatible EDA files or any planned releases.

4. Community Assistance:

   • Engage with online forums or communities focused on hardware design. Other engineers may have developed workarounds or could share their own converted files.

5. Manual Recreation:

   • As a last resort, consider manually recreating the necessary components in PCAD using datasheets and specifications from Nvidia’s documentation.

6. Documentation and Resources:

   • Regularly check Nvidia’s official documentation for any updates regarding EDA file availability or new resources that may become available.

7. Best Practices for Future Projects:

   • When starting new projects, confirm the availability of necessary design files in your preferred format before selecting hardware components to avoid similar issues.

By following these steps, users can effectively troubleshoot and find solutions to their EDA file compatibility issues with the Nvidia Jetson Orin Nano Dev board.
