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. In Arria 10 and Cyclone 10 GX devices, setting this option for a pin or a single-output logic function signal is equivalent to feeding the signal through a GLOBAL buffer of the specified type. In all other families, the buffer type is not specified. Rather, a setting of \"On\" specifies that the signal must use global routing to route to all destinations (or specified subset). Alternatively, a setting of \"On - Auto Promote Fanout\" on the source specifies that global routing must be used for all destinations, except those that the fitter would normally not consider automatically. In all families, 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.
