get clock feeding pin

Hi all,

I need to retrieve the clock feeding a specific pin in quartus. It seems there is no available command that can do that.

I found this description on Intel web site that illustrates how to do by writing a whole procedure.

I've tested this procedure but it seems not working.

Has anyone encountered something like this?

Is there another way to do that?
