A logic option that specifies whether the signal should be available throughout the device on the global routing paths. Global signals can be both pin- and logic-driven. Clock, output enable, register control, and memory control signals can be global signals. Turning on this option for a pin or a single-output logic function signal is equivalent to feeding the signal through a GLOBAL buffer. Turning off this option for a particular signal prevents any of the Auto Global options from using the signal as an automatic global signal.
This option is available for all Altera devices.
For these supported device(ArriaIIGX, and Stratixseries) families, a setting of on is equivalent to "global clock".
