route clock to clocknet

Hi, i get a clocksignal in on a clockpin, and i want to use that signal to drive both a module in my sopc builder system and a custom module outside of it. Is the signal automatically routed to a clocknet, if not what do i need to do to make it so?

another question, is it okay to drive logic directly from an external signal, or should i use a pll to stabilize it?

i use a cyclone iv by the way
