    The meaning of Export is that it does not get connected to the Avalon Bus side of the design, but gets "Exported" out of the SoPC (sub)system for connection either in the larger design or to the outside world.

    Clk is typically found by scrolling upward in the GUI, and can only be assigned to signals that are "cast" into a certain type of interface.
