Figure 5–3. Input Register Setup & Hold Timing Diagram
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 and the
timing is specified up to the output pin of 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 standards.
The following measurements are made during device characterization.
Altera measures clock-to-output delays (t
minimum voltage, and maximum temperature (PVT) for default loading
conditions shown in
clock pin to output pin timing for Stratix II devices.
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.
