GLOBAL_SIGNAL
GLOBAL_SIGNAL
Type
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.
