Global Signal logic option
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 Arria® 10, Cyclone® 10 GX, and Stratix® 10 devices. Stratix® 10 devices only support the global clock and off options.
