1.10.8. Assignments Made in HDL Source Code in Exported Partitions

Assignments made with I/O primitives or the altera_attribute HDL synthesis attribute in lower‑level partitions are passed to the top-level design, but do not appear in the top-level .qsf file or Assignment Editor. These assignments are considered part of the source netlist files. You can override assignments made in these source files by changing the value with an assignment in the top-level design.
