The numbers in this table are tested using the methodology presented in
Table 77
This clock-to-output time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock Input or a
standard other than LVCMOS25 with 12 mA drive and Fast slew rate is assigned to the data Output. If the former is true, add the appropriate
Input adjustment from
DCM output jitter is included in all measurements.
For minimums, use the values reported by the Xilinx timing analyzer.

When reading from the Output
Flip-Flop (OFF), the time from the
active transition on the Global Clock
pin to data appearing at the Output
pin. The DCM is used.
When reading from OFF, the time
from the active transition on the
Global Clock pin to data appearing at
the Output pin. The DCM is not used.
