For output timing, different I/O standards require different baseline loading
techniques for reporting timing delays. Altera characterizes timing delays with the
required termination for each I/O standard and with 0 pF (except for PCI and PCI-X,
which use 10 pF) loading. The timing is specified up to the output pin of the FPGA
device. The Quartus II software calculates I/O timing for each I/O standard with a
default baseline loading as specified by the I/O standards.
The following measurements are made during device characterization. Altera
measures clock-to-output delays (t

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 Stratix III Device Handbook. Perform the following steps:
1. Simulate the output driver of choice into the generalized test setup using values
2. Record the time to V
3. Simulate the output driver of choice into the actual PCB trace and load using the
4. Record the time to V

appropriate IBIS model or capacitance value to represent the load.
