Hello... This *might* be an answer. But I think there is a bug in Quartus Prime Lite (version 19.1) running on Ubuntu 16.04.

I have found that the timing analyzer can't find lower case .sdc filename extensions. For example it can't find "MyProject.sdc" but it does find "MyProject.SDC".

Note that the "main" quartus program is also sensitive to the case, but as long as you tell it the right name, it finds it. So the bug is specific to the timing analyzer. A work-around is to start new projects with the Synopsis Design Constraint file(s) always having the extension .SDC - uppercase.

Perhaps this is a bug from porting code from MS-DOS and early versions of Windows which treated all file names as uppercase?

PS: I'm new to this biz. How does one officially tell Intel about a suspected bug?

    Hi Peter,

    I guess I don't have the sdc file at all in the project specified. So I cannot decide the validity of your query. But I will try to look into it and see if I face the similar issue. You can message this person https://forums.intel.com/s/profile/0050P000008xvavQAA who is from Intel. Thanks!
