I/O Timing Measurement Methodology
Different I/O standards require different baseline loading techniques for
reporting timing delays. Altera characterizes timing delays with the
required termination and loading for each I/O standard. The timing
information is specified from the input clock pin up to the output pin of

The Quartus II software models 270 ps of delay on the PLL dedicated clock
output (PLL6_OUT[3..0]p/n and PLL5_OUT[3..0]p/n) pins both when
used as clocks and when used as I/O pins.
