17 years agoThe altclkctrl block can be instantiiated IF you want to use some of it's special features(like muxing or enable). But a global output always goes through the ctrlblock and onto a global(unless it's a dedicated output). You won't see GLOBAL or anything in the TimeQuest report, but you should see the CLKCTRL block if you do a report_timing -detail full_path.
In the Fitter Report, there is also a section called Global Signals, which should have it listed there. As for forcing onto/off of global, I tend to let Quartus make it's decisions, and only if I think it did something wrong will I modify it. With your system having one clock and one reset, they'll probably both go on globals and that's what you want. Here's a doc about Recovery/Removal timing, which is basically understanding reset and recovery. Probably more than you asked, but thought I'd link it: http://www.alteraforum.com/forum/showthread.php?t=2158&highlight=recovery
