XQ4028EX Switching Characteristic Guidelines
Testing of the switching parameters is modeled after testing
methods specified by MIL-M-38510/605. All devices are
100% functionally tested. Internal timing parameters are
derived from measuring internal test patterns. Listed below
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.
When fewer vertical clock lines are connected, the clock dis-
tribution is faster; when multiple clock lines per column are
driven from the same global clock, the delay is longer. For
more specific, more precise, and worst-case guaranteed
data, reflecting the actual routing structure, use the values
provided by the static timing analyzer (TRCE in the Xilinx
Development System) and back-annotated to the simulation
netlist. These path delays, provided as a guideline, have
been extracted from the static timing analyzer report. All
timing parameters assume worst-case operating conditions
(supply voltage and junction temperature)

Notes:
1.
These values include a minimum load of one output, spaced as far as possible from the activated pull-up(s). Use the static timing
analyzer to determine the delay for each destination.
