)
allows you to automatically assign a designator to the components,
and for multiparts components, assign a multipart suffix to minimize
the number of these packages.
The menu is:
Various possibilities are
available :
Annotate all the components (option
all components checked)
Annotate new components only (i.e.
those whose reference finishes by? like IC? ) (new components
only option checked).
Annotate the whole hierarchy (check
Project option).
Annotate the current sheet only
(Check Current Sheet).
Except in particular cases, an
automatic annotation applies to the whole project (all sheets) and
to the new components, if you don't want to modify previous
annotations.
