-# This device exists only because there are some devices that I don't
-# want to have a Platform parameter because it would cause a cycle in

-# The real solution to this problem is to pass the ParamXXX structure
-# to the constructor, but with the express condition that SimObject
-# parameter values are not to be available at construction time.  If
-# some further configuration must be done, it must be done during the
-# initialization phase at which point all SimObject pointers will be
-# valid.
