Anyone has similiar statement for a Cyclone V SoC devboard? Using 5CSEMA4u23c6? I read almost everything datasheet-wise and they don't make any definite statement other then "Quartus will limit it to whatever the device is capable of".

I think the datasheets got worse over time (I'm with Altera since Cyclone I times).
