Notes to
(1) You can set this value in the Quartus II software by selecting D1, D2, D3, D4, D5, and D6 in the Assignment Name column.
(2) Minimum offset does not include the intrinsic delay.
(3) For the EP4SGX530 device density, the IOE programmable delays have an additional 5% maximum offset.

Table 1–50. Worst-Case DCD on Stratix IV I/O Pins
Altera offers two ways to determine I/O timing—the Excel-based I/O Timing and the
Quartus II Timing Analyzer.
Excel-based I/O Timing provides pin timing performance for each device density and
speed grade. The data is typically used prior to designing the FPGA to get an estimate
of the timing budget as part of the link timing analysis. The Quartus II Timing
Analyzer provides a more accurate and precise I/O timing data based on the specifics
of the design after you complete place-and-route.
The Excel-based I/O Timing spreadsheet is downloadable from the
