3.8.6. Viewing Quartus Database File Information

Although you cannot directly read a .qdb file, you can view helpful attributes about the file to quickly identify its contents and suitability for use.

The Intel® Quartus® Prime software automatically stores metadata about the project of origin when you export a Quartus Database File (.qdb). You can then use the Quartus Database File Viewer to display the attributes of any of these .qdb files.

Figure 35. Quartus Database File Viewer
Follow these steps to view the attributes of a .qdb file:
  1. In the Intel® Quartus® Prime software, click File > Open, select Design Files for Files of Type, and select a .qdb file.
  2. Click Open. The Quartus Database File Viewer displays project and resource utilization attributes of the .qdb.

    Alternatively, run the following command-line equivalent:

    quartus_cdb --extract_metadata --file <archive_name.qdb> \
         --type quartus --dir <extraction_directory> \
