get unconstrained pathes with quartus_sta shell script / qsta_experiment.tcl

Hello!

I would like to report unconstrained pathes within an automated tcl script.

quartus_sta commands like "report_ucp" and "check_timing" do their reporting only to the Panel, stdout, or to a file.

With "get_report_panel_data" i have managed to get the data from the Panel, but of course this only works if the GUI is open.

I would like to just use "foreach_in_collection" loops rather than parsing report files.

The "qsta_experiment.tcl" script which can be found in the quartus/common/tcl/internal folder seems to be exact what i am looking for.

This script reports these extra metrics if enabled via quartus.ini, which are for example unconstrained ports/pathes.

Unfortunately the ports which are listed seems also to include ports with "set_false_path" assignments, which results to an incorrect report.

Is there a (simple/prefered) way to get a list of "really" unconstrained ports like the "report_ucp" command, or a way to get the results within tcl in a shell only setup?

Any hint is welcome, thanks!

Dirk
