\paragraph{Functional Groups.}
At low levels of design, components
are brought together to interact and perform
given functions. We can call these collections
of components `functional groups'.
%
For instance we may have a handful of components
brought together to perform a simple function
like amplifying a signal or a power supply.
%
The components in a {\fg} can be considered
to be `functionally~adjacent' to each other, in that
they interact with each other to perform
as a higher level component.

other FMMD datatypes are described in Section \ref{fg}.
