What is a(n) OPJ file?

The OPJ (OrCAD Project Format) file format is a binary file type used by Cadence OrCAD, a suite of electronic design automation tools. The file contains several elements such as schematics, components, layouts, Netlists, and bills of material. It also stores information about the project’s properties, such as design rules and constraints.

OPJ files can be opened and edited with the official Cadence OrCAD suite or with various third-party applications that support the format. However, the file format is not compatible with most other design automation tools, requiring conversion into an alternative format for use in other software.
