Spartan-XL Family Pin-to-Pin Output 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.

Notes:
1.
Output delays are representative values where one global clock input drives one vertical clock line in each accessible column,and
where all accessible IOB and CLB flip-flops are clocked by the global clock net.
2.
Output timing is measured at ~50% VCC threshold with 50 pF external capacitive load.
3.
OFF = Output Flip Flop
