Convert BRD to DSN

Understanding BRD and DSN file formats

BRD files are PCB (Printed Circuit Board) design files commonly created by EAGLE, a popular PCB design software. These files contain schematic layouts, component placements, and routing information for electronic circuit boards.

DSN files are Design files used by various PCB design tools, most notably by Specctra and Altium Designer. DSN files are typically used for design netlists and are essential for PCB autorouting and manufacturing processes.

Why convert BRD to DSN?

Converting a BRD file to a DSN file is often necessary when you need to use advanced autorouting tools like Specctra or when collaborating with manufacturers or engineers who require the DSN format for further processing or simulation.

How to convert BRD to DSN

The most reliable way to convert a BRD file to a DSN file is by using EAGLE in combination with the ULP (User Language Program) script called export-dsn.ulp. This script is specifically designed to export EAGLE BRD files to the DSN format.

Step-by-step conversion process

1. Open your BRD file in Autodesk EAGLE.
2. Download the export-dsn.ulp script from the official EAGLE ULP repository or trusted sources.
3. In EAGLE, go to File → Run ULP and select export-dsn.ulp.
4. Follow the on-screen prompts to generate the DSN file. The output DSN file will be saved in your project directory.

Best software for BRD to DSN conversion

• Autodesk EAGLE (with export-dsn.ulp script) – The most accurate and widely used method.
• Altium Designer – Can import EAGLE BRD files and export DSN files, but may require additional steps for compatibility.

Tips for successful conversion

• Always verify the integrity of the exported DSN file by opening it in your target autorouter or PCB tool.
• Check for any missing or misinterpreted components after conversion, especially for complex designs.
• Keep your EAGLE and ULP scripts updated to ensure compatibility with the latest file formats.
