QSF comparison

I have been working on the timing constraints for my chip. I found it easier to use the GUI that Timequest provides.

To actually release the chip however I must use a scripted build process, for repeatability reasons.

Anyway, I now find myself in the situation where my constraints file results in a fully constrained and compliant chip when I build in the Quartus GUI. When I run the scripted build process some constraints are violated.

I assume that this is because I have different QSFs for the GUI and scripted builds.

Does anyone have a tool that would allow me to find the differences between two QSF files?

I've been using BeyondCompare, but the files are in very different orders and so the comparison is difficult.

    Project -> Organize Quartus II Settings File will put them in a common order, so you can easily compare by site with any text editor(that has line numbers). If you like the current order, then just back up your .qsf as it is, and after finding the differences, you can go back to the old one.

    (If they're different revisions, then project -> Revisions -> Compare should do it.)
