[CDC] How can I do Cross Domain Checks in Quartus?

what's flow it's better - letting the Design Assistant run automatically during compilation or run it when all the flow was finished?

Does it have a big impact on the compilation time?

In the project, which I'm working on, all the options are checked/selected on (including the automatically run)... Is it possible to know how time was spent on that (besides 'try&see')?

Does Quartus report how long time it spend on each stage?
