How to change the default name of *.sof file in Quartus

[Altera_Forum]

Dear Altera Users, 

  Where can I change the default *.sof name in the settings of quartus ? I want to create different files (file1.sof, file2.sof, ....) different compilations for the project, so I can avoid to recompile again and again, I want also to avoid to create different projects for this reason.  thanks for your help   best regards Chahid

You can change the directory where the output files go by going to Assignments->Settings and selecting Compilation Process Settings on the left. Under Save project output files in specified directory, change Directory name: as needed (default is output_files). You need a separate directory for all the output files because your changed settings will probably make changes to several intermediate files before the final sof file is generated.

What I do is have a post-flow script run at the end of each compile and put the .sof and .rbf into a folder with a revision number in the name of the folder. I have quartus configured to put the build outputs into a build_outputs folder in the project directory and then have a simple tcl script copy and rename the files. In the qsf I use the post flow script assignment to execute my script: 

set_global_assignment -name POST_FLOW_SCRIPT_FILE "<path_to_my_script>.tcl"

 I find the option Assignement -> settings -> compilation process setting (activate save project output files in specified directory + putting directory names), is working find and automatically, Thank you very much.   regards chahid
