Spartan-XL Family Pin-to-Pin Input Parameter Guidelines
All devices are 100% functionally tested. Pin-to-pin timing
parameters are derived from measuring external and inter-
nal test patterns and are guaranteed over worst-case oper-
ating conditions (supply voltage and junction temperature).
Listed below are representative values for typical pin loca-
tions and normal clock loading.
Spartan-XL Family Setup and Hold
Capacitive Load Factor
Figure 35 shows the relationship between I/O output delay
and load capacitance. It allows a user to adjust the specified
output delay if the load capacitance is different than 50 pF.
For example, if the actual load capacitance is 120 pF, add
2.5 ns to the specified delay. If the load capacitance is 20
pF, subtract 0.8 ns from the specified output delay.
Figure 35 is usable over the specified operating conditions
of voltage and temperature and is independent of the output
slew rate control.

Notes:
1.
IFF = Input Flip-Flop or Latch
2.
Setup time is measured with the fastest route and the lightest load. Hold time is measured using the furthest distance and a
reference load of one clock pin per IOB/CLB.
