Convert GDS to WS

Understanding GDS and WS file formats

GDS (Graphic Data System) files, also known as GDSII, are industry-standard binary files used for representing the physical layout of integrated circuits (ICs) in electronic design automation (EDA). These files store geometric shapes, layers, and other information necessary for chip fabrication.

WS files are typically associated with L-Edit or Waveform Simulation tools, often used for storing simulation data, waveform information, or workspace settings in EDA environments. The exact structure of a WS file can vary depending on the software that uses it.

Why convert GDS to WS?

Converting a GDS file to a WS file is often necessary when you want to simulate or analyze the physical layout data within a waveform or simulation environment. This conversion allows designers to verify circuit behavior based on the actual layout.

How to convert GDS to WS

Direct conversion from GDS to WS is not always straightforward, as these formats serve different purposes. Typically, the process involves importing the GDS file into an EDA tool that supports both formats and then exporting or saving the data as a WS file.

Recommended software for GDS to WS conversion

• L-Edit (by Tanner EDA): L-Edit is a popular layout editor that can import GDS files and save workspace or simulation data as WS files. To convert, use File → Import → GDSII to open your GDS file, then File → Save Workspace or File → Export → WS (depending on your version).
• Mentor Graphics Pyxis: This EDA suite can also handle GDS files and export simulation or workspace files in WS format. Use File → Open for GDS, then File → Save As and select WS as the target format.

Tips for successful conversion

• Ensure your EDA tool supports both GDS and WS formats.
• Check for any data loss or format incompatibility after conversion.
• Consult your software documentation for specific import/export instructions.

Conclusion

Converting GDS files to WS format is best accomplished using specialized EDA tools like L-Edit or Mentor Graphics Pyxis. These tools ensure accurate data transfer and compatibility for simulation or further design work.
