TimeQuest timing relationship for unrelated clocks

Thank you for the response, Cris72. I think I did not clarify my question well enough, as you have answered a question I did not intend.

I am not interested so much in techniques to properly constrain the signals. Where a signal crosses a clock domain, I will add a register-to-register false path and cut the timing analysis for that signal altogether. And I will use anti-metastability registers.

What I am looking for is a way to be certain that TimeQuest will give me a timing violation if I have not put the false path constraint on a domain crossing signal.
