1.9. Exporting Compilation Results

The Quartus® Prime Compiler writes the results to a set of database files. You can run a command to export the compilation results database as a single Quartus Database File (.qdb).

After running design compilation, the exported .qdb file contains the data to reproduce similar compilation results in another project, or in a later software version. You can export your project's compilation results database for import to another project or migration to a later Quartus® Prime software version.

You can export the .qdb for your entire project or for a design partition that you define in your project. When migrating the database for an entire project, you can export the compilation database in a version-compatible format to ensure compatibility for import to a later software version. Although you cannot directly read the contents of the .qdb file after export, you can view attributes of the database file in the Quartus Database File Viewer.

Table 18.  Exporting Compilation Results
To Export Compilation Results For Method Description
Complete Design Click Project > Export Design Saves compilation results for the current project revision in a version-compatible Quartus database file (.qdb) that you can import to another project or migrate to a later version of the Quartus® Prime software. You can export the results for the synthesized or final compilation snapshot.
Note: Not supported for Agilex™ family devices.
Design Partition Click Project > Export Design Partition Saves compilation results for a design partition as a Partition Database File (.qdb) that you can import to another project using the same version of the Quartus® Prime software. You can export the results for the synthesized or final compilation snapshot.
