When I instantiate an EMIF in my Qsys design for Cyclone 10 and select a 4GB component preset result does not have 4GB of addressable space?

When I instantiate an EMIF in my Qsys design for Cyclone 10 and select a 4GB component preset the interface presents me with an Avalon Memory Mapped port with an Address width of 25 and a data width of 128. This results in a total addressable space of 512MB... Am I missing something?

    Hi Sir,

    Welcome to Intel Community.

    Can you provide the full name of the preset selected? Because I didn't found any 4GB(yte) preset available in Cyclone 10 . What I've seen is only 4Gb(it) as shown below. Please help to confirm .

    Thanks

    Regards,

    Aida
