What is a CVG file?
The .CVG file extension typically represents a PCB assembly data exchange file. Engineers use these files to transfer printed circuit board (PCB) layouts and manufacturing data between design software and fabrication systems. These files comply with the IPC-2581 Standard and are based on the XML format.
Additionally, .CVG can stand for a Calamus Vector Graphic File. The company invers created this format for use with the legacy Calamus desktop publishing software. In scientific contexts, a .CVG file might also store chemical kinetics solution data for Ansys CHEMKIN.
How to open CVG files?
You can open engineering .CVG files using professional electronic design automation (EDA) software like Altium Designer. If the file contains historical vector graphics, you will need Calamus. For chemical data, use Ansys CHEMKIN.
Best practices and troubleshooting
If you cannot open a .CVG file with standard CAD software, you can inspect its contents using a plain text editor. Because the primary IPC-2581 standard utilizes an XML structure, editors like Notepad++ or Visual Studio Code can reveal the raw design tags and confirm the file type.
Software and tools
Summary
viewer.online/cvg analyzes .CVG files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Since .CVG has multiple possible meanings, we recommend using viewer.online/cvg to identify the actual format of the user's file. Because .CVG files use the known XML format, viewer.online/cvg can safely open and display them online, eliminating compatibility problems.
