Altera Quartus II Settings File - Manual (Page 573)

GLOBAL_SIGNAL
Specifies whether the signal should be routed using global routing paths. Global signals can be both pin-
and logic-driven, and can be any signal in the design. Turning this option on for a pin or a single-output
logic function signal is equivalent to feeding the signal through a GLOBAL buffer. Turning this option off
for a particular signal will prevent any of the Auto Global options from using the signal as an automatic
global signal.
