The word "design" in "top-down design" means something different from
how you are using it.  For some people "design" means an unspecified
something that isn't code.  A "design" in the "top-down design" sense
is already implementation.  It isn't a complete implementation, as
some things are left out, most prominently subfunctions that are
called but not yet written, but it is still implementation.  The idea
that a top-down design can be implemented bottom-up doesn't make
sense, because the top levels have already been implemented.  So I
infer from this that you mean something different when you say
"design".
