2.3.1. Option Precedence
- Intel® Quartus® Prime Settings File (.qsf)
- The compiler database
- Command-line options
The .qsf file contains all the project-wide and entity-level assignments and settings for the current revision for the project. The compiler database contains the result of the last compilation in the /db directory, and reflects the assignments at the moment when the project was compiled. Updated assignments first appear in the compiler database and later in the .qsf file.
Command-line options override any conflicting assignments in the .qsf file or the compiler database files. To specify whether the .qsf or compiler database files take precedence for any assignments not specified in the command-line, use the option --read_settings_files.
Option Specified | Precedence for Reading Assignments |
---|---|
--read_settings_files = on (Default) |
|
--read_settings_files = off |
|
The --write_settings_files command-line option lists the locations to which assignments are written..
Option Specified | Location for Writing Assignments |
---|---|
--write_settings_files = on (Default) | .qsf file and compiler database |
--write_settings_files = off | Compiler database |
Any assignment not specified as a command-line option or found in the .qsf file or compiler database file is set to its default value.
Use the options --read_settings_files=off and --write_settings_files=off (where appropriate) to optimize the way that the Intel® Quartus® Prime software reads and updates settings files.
