Why doesn't the global or per pin assignment for the unused transceiver channel work for the Stratix®10 L- or H-Tile design when all the channels in a transceiver tile are unused?

Description

In the Stratix®10 L- or H-Tile design, for the preserve unused channel QSF to take effect, at least one channel in a transceiver tile needs to be instantiated in the design. You can create a dummy channel in a Tile, and apply the global or per pin assignment.

Resolution

There is currently no plan to fix this problem.
