No, the simulators in sim/ get linked directly into GDB.  Other, more
modern simulators run standalone and talk over a socket.  Qemu for
instance.

I don't think you will find anyone else out here that knows about
the ARMulator, though.  It hasn't seen active development in a really
long while.

I think that ARM uses those to control their own simulators.
