Why is the enable_dpa_fifo parameter set to "UNUSED" in the generated file even if you enabled the DPA feature in the ALTLVDS_RX MegaWizard

Description

You will see the following parameter definition in the MegaWizard™ generated file, although you already enabled the DPA feature in ALTLVDS_RX.

"ALTLVDS_RX_component.enable_dpa_fifo = "UNUSED""

Resolution

You can safely ignore this parameter. This is a legacy parameter used in  Stratix® devices. It has no effect on later devices.
