Spartan IOB Output Switching Characteristic Guidelines
Testing of 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. For more specific, more precise,
and worst-case guaranteed data, use the values reported
by the static timing analyzer (TRCE in the Xilinx Develop-
ment 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 (sup-
ply
voltage
and
junction
temperature).
Values
are
expressed in nanoseconds unless otherwise noted.

Notes:
1.
Delay adder for CMOS Outputs option (with fast slew rate option): for -3 speed grade, add 1.0 ns; for -4 speed grade, add 0.8 ns.
2.
Delay adder for CMOS Outputs option (with slow slew rate option): for -3 speed grade, add 2.0 ns; for -4 speed grade, add 1.5 ns.
3.
Output timing is measured at ~50% VCC threshold, with 50 pF external capacitive loads including test fixture. Slew-rate limited output
rise/fall times are approximately two times longer than fast output rise/fall times.
4.
Voltage levels of unused pads, bonded or unbonded, must be valid logic levels. Each can be configured with the internal pull-up
(default) or pull-down resistor, or configured as a driven output, or can be driven from an external source.
