ContributorDDIO Input Speed Cyclone V vs. Cyclone 10GX
When I create a simple DDIO input for both the Cyclone V and Cyclone 10GX parts, the Cyclone V has an Fmax about twice the Cyclone 10GX.
Cyclone V, Fmax ~ 400Mhz
Cyclone 10GX, Fmax < 200...

The EMIF interface required a lot of resources. This may not applicable to instantiate 8 interfaces in a design.
An Altera GPIO IP can support a maximum interface frequency of 300 MHz. This will limit the clock rate of the design.
This is the limitation of the IP itself.
