the FPGA device. The Quartus II software calculates the I/O timing for
each I/O standard with a default baseline loading as specified by the I/O
standard.
Altera measures clock-to-output delays (t
minimum voltage, and maximum temperature (PVT) for the 3.3-V LVTTL
I/O standard with 24 mA (default case) current drive strength setting and
fast slew rate setting. I/O adder delays are measured to calculate the t
change at worst-case PVT across all I/O standards and current drive
strength settings with the default loading shown in
page
across worst-case PVT for all I/O standards and drive strength settings.
These three pieces of data are used to predict the timing at the output pin.
Simulation using IBIS models is required to determine the delays on the
PCB traces in addition to the output pin delay timing reported by the
Quartus II software and the timing model in the device handbook.

Record the time to VMEAS.
Simulate the output driver of choice into the actual PCB trace and
load, using the appropriate IBIS input buffer model or an equivalent
capacitance value to represent the load.
Record the time to VMEAS.
Compare the results of steps 2 and 4. The increase or decrease in
delay should be added to or subtracted from the I/O Standard
Output Adder delays to yield the actual worst-case propagation
delay (clock-to-input) of the PCB trace.
