Spartan-XL Pin-to-Pin Output Parameter Guidelines
Testing of switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Pin-to-pin timing parameters are derived from measuring external and internal test patterns and are
guaranteed over worst-case operating conditions (supply voltage and junction temperature). Listed below are representative
values for typical pin locations and normal clock loading.
Spartan-XL Output Flip-Flop, Clock-to-Out
Note 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.
Note 2: Output timing is measured at ~50% V
CC
threshold with 50 pF external capacitive load.
Spartan-XL Pin-to-Pin Input Parameter Guidelines
Testing of switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Pin-to-pin timing parameters are derived from measuring external and internal test patterns and are
guaranteed over worst-case operating conditions (supply voltage and junction temperature). Listed below are representative
values for typical pin locations and normal clock loading.
Spartan-XL Setup and Hold
Note 3: 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.
