Programmable Output Buffer Delay
Table 1-77: Programmable Output Buffer Delay for Arria V Devices
is table lists the delay chain settings that control the rising and falling edge delays of the output buffer.
You can set the programmable output buffer delay in the Quartus Prime sofꢂare 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.
(112)
(113)
You can set this value in the Quartus Prime sofꢂare by selecting D1, D3, D4, and D5 in the Assignment Name column of Assignment Editor.
Minimum offset does not include the intrinsic delay.
