You seem to be thinking at too low a level. There isn't any "mocked H/W", only
mocked behavior. The H/W simulation bodies give the information or have the
effect expected of the devices given the state of the reality modeled in the
environment pkg, but they need have no similarity to the real bodies, and
usually don't. The device may be memory mapped, but there's no reason for the
simulation to be. If access the device takes appreciable time, that's usually
simulated using a delay. There's usually no reason to limit these parts of the
S/W to the constraints of the target run time.
