Product Specification
R
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.
Figure 7 shows the common structure of the global signal
trees. The pin input is buffered, then drives multiple internal
global signal traces to deliver low skew and reduce loading
delays. GCK, GSR, and GTS can also be used as general
purpose I/Os if they are not needed as global signals. The
DataGATE assertion rail is also a global signal.
