The numbers in this table are tested using the methodology presented in
Table 76
This time requires adjustment whenever a signal standard other than LVCMOS25 with 12 mA drive and Fast slew rate is assigned to the data
Output. When this is true, add the appropriate Output adjustment from
R
and
Table
When reading from the
Output Flip-Flop (OFF), the
time from the active transition
at the OCLK input to data
appearing at the Output pin
The time it takes for data to
travel from the IOB’s O input
to the Output pin
The time it takes for data to
travel from the O input
through the OFF latch to the
Output pin
Time from asserting the
OFF’s SR input to
setting/resetting data at the
Output pin
Time from asserting the
Global Set Reset (GSR)
input on the
STARTUP_SPARTAN3E
primitive to setting/resetting
data at the Output pin
