nally generated DataGATE control logic can be assigned to
this I/O pin with the BUFG=DATA_GATE attribute.
Global Signals
Global signals, clocks (GCK), sets/resets (GSR), and output
enables (GTS), are designed to strongly resemble each
other. This approach enables design software to make the
best utilization of their capabilities. Each global capability is
supplemented by a corresponding product term version.

global signal traces to deliver low skew and reduce loading
delays. GCK, GSR, and GTS can also be used as general
