Programmable IOE Delay
Table 1–52 lists the Stratix IV IOE programmable delay settings.
Programmable Output Buffer Delay
Table 1–53 lists the delay chain settings that control the rising and falling edge delays
of the output buffer. The default delay is 0 ps.

Notes to Table 1–52:
(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.

Note to Table 1–53:
(1) You can set the programmable output buffer delay in the Quartus II software by setting the Output Buffer Delay
Control assignment to either positive, negative, or both edges, with the specific values stated here (in ps) for the
Output Buffer Delay assignment.
