2.2.3. Generating Intel® Quartus® Prime Settings Files
Intel® Quartus® Prime software allows you to generate .qsf files from your revision. You can embed these constraints in a scripted compilation flow, and even create sets of .qsf files for design optimization.
To generate a .qsf file from the Intel® Quartus® Prime software, click Assignments > Export Assignments.
To organize the .qsf in a human readable form, Project > Organize Intel® Quartus® Prime Settings File.
Organized .qsf File
This example shows how .qsf files characterize a design revision. The set_global_assignment command makes all global constraints and software settings and set_location_assignment constrains each I/O node in the design to a physical pin on the device.
