# Quartus® II Tcl Automatically Archiving Projects

By

When you do many compilations and vary different settings during each compilation, it can be hard to remember what your settings and results were from compile to compile. By archiving a project, you can preserve a complete copy of it, including the files generated during a compile. You can archive a project with a single command at a system command- prompt, but creating a Tcl script and adding a setting to execute it automatically makes the process easier.

To make the script run automatically at the end of every compilation, use the following script, and add a new assignment to your project. The assignment name is POST_FLOW_SCRIPT_FILE. For more information on this assignment, refer to the Automatic Script Execution examples. Assuming the script is named autoqar.tcl, add the following assignment to your Quartus II Settings File (.qsf):

set_global_assignment -name POST_FLOW_SCRIPT_FILE quartus_sh:autoqar.tcl

The script creates a file name based on the current date and time. For information about changing the date and time representation, refer to the Date & Time Formatting page.

# Use these options to control what files get archived.
# -include_outputs: Includes Quartus II output files, including the

# -include_libraries: Includes system libraries referenced in your
#     project

# and the current time.
