is linked to => "RAM version"

There are two main ARM virtual Fixed Virtual Platform (FVP) models,
`Versatile Express (VE) FVP and BASE FVP

platform using the license-free Foundation_v8 simulator. Fortunately,
the Foundation_v8 simulator also supports the BASE_FVP model which
companies can purchase licenses for and contain much more functionality.
