The numbers in this table are tested using the methodology presented in
Table 77
This setup time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock Input or the data
Input. If this is true of the Global Clock Input, subtract the appropriate adjustment from
appropriate Input adjustment from the same table.
This hold time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock Input or the data
Input. If this is true of the Global Clock Input, add the appropriate Input adjustment from
appropriate Input adjustment from the same table. When the hold time is negative, it is possible to change the data before the clock’s active
edge.
DCM output jitter is included in all measurements.
and
When writing to the Input
Flip-Flop (IFF), the time from the
setup of data at the Input pin to
the active transition at a Global
Clock pin. The DCM is used. No
Input Delay is programmed.
When writing to IFF, the time
from the setup of data at the
Input pin to an active transition
at the Global Clock pin. The
DCM is not used. The Input
Delay is programmed.
When writing to IFF, the time
from the active transition at the
Global Clock pin to the point
when data must be held at the
Input pin. The DCM is used. No
Input Delay is programmed.
When writing to IFF, the time
from the active transition at the
Global Clock pin to the point
when data must be held at the
Input pin. The DCM is not used.
The Input Delay is programmed.
