Honored ContributorI've had the same problems originally. I found that looking for help on TimeQuest in paper form is quite hard, the manuals are all a bit fuzzy. However, I stumbled over the Altera video training on their webpage and it does give you quite a good overview how to constrain stuff, at least the stuff that needs to be constrained in every project:
This one is the basic on TimeQuest analyser, you can skip most of the basic stuff, if you've been working with it for a while (even though I found stuff in there I didn't know yet). This is the one, that explains how to set up clocks (internal/external): http://www.altera.com/education/training/courses/odsw1115 I admit, setting virtual clocks didn't work for me, somehow, so I managed without. This one explains to you, how to constrain inputs and outputs (at least source synchronous ones). This has the examples I used to successfully constrain my I/O's: http://www.altera.com/education/training/courses/omem1120 The second one is based on an older version of Quartus II I think, but it works nonetheless. Hope that helps. Above two video trainings I found to be elemental to understand why and which constraints are needed and how to implement then. Ah yes, training's free of course.
