Convert MPH to PLD

Understanding the mph and pld file formats

MPH files are project files created by COMSOL Multiphysics, a powerful simulation software used for modeling and simulating physics-based problems. These files store geometry, physics settings, mesh, study steps, and results.

PLD files, on the other hand, are typically associated with PLD (Polygon Layer Data) formats, often used in photolithography, PCB design, or other CAD/CAM applications to describe polygonal shapes and layers for manufacturing processes.

Why convert mph to pld?

Converting an MPH file to a PLD file is necessary when you need to transfer simulation geometry or mask layouts from COMSOL to a CAD/CAM or photolithography tool that accepts the PLD format. This is common in microfabrication, MEMS, or PCB design workflows.

How to convert mph to pld

There is no direct, one-click converter for MPH to PLD due to the specialized nature of both formats. However, you can follow these steps:

1. Open your MPH file in COMSOL Multiphysics.
2. Export the geometry or mask layout to a common CAD format such as DXF or GDSII:
   • Go to File → Export → Export and select DXF or GDS as the output format.
3. Use a CAD tool or a dedicated converter (such as KLayout or LayoutEditor) to open the exported file.
4. Export or save the file as PLD format if supported, or use a script/plugin to convert the geometry to PLD.

Recommended software for conversion

• COMSOL Multiphysics: For exporting geometry to DXF or GDSII.
• KLayout: Free, open-source tool for viewing and converting GDSII/DXF to other formats, with scripting support for custom conversions.
• LayoutEditor: Supports a wide range of mask layout formats and can be used for further conversion to PLD if supported.

Tips for successful conversion

• Always verify the exported geometry in the intermediate format before converting to PLD.
• Check layer mapping and scaling to ensure compatibility with your target PLD application.
• If a direct PLD export is not available, consider contacting your CAD tool vendor for plugin or script support.
