PCB to Schematic
You can re-annotate the board either manually (editing the part reference labels) or globally
from the automatic annotator command on the PCB Layout tools menu.
Launching the Automatic Annotator
When live netlisting is on, this will automatically reflect to the schematic. With live netlisting off,
the schematic will update and the layout will then lock as the netlist has changed and needs to
be manually passed through to the layout.
General Netlisting Rules
There are several important rules of thumb to understand about netlisting in Proteus.
When live netlisting is on, a change that adds connectivity will happen automatically (e.g.
adding a wire on the schematic will add a ratsnest on the layout). If you make a change that
removes connectivity the layout will show the change by dimming the deleted objects and you
will need to manual confirm the operation.
When live netlisting is off (batch netlisting) any and all changes to the netlist will require you to
unlock and apply the netlist before you can continue working on the layout.
Clicking on changes pending to remove footprints that have been deleted on the schematic will
also remove associated tracks. If you want to remove footprint only and leave the tracks simply
delete the part in the layout (rather than Proteus).
Dimmed objects in the layout are visual placeholders only - they do not exist on the board. Best
practice is always to click on changes pending on the connectivity status and to arrange the
layout to conform to the schematic.
Imported projects (from older versions) will always start with live netlisting off as there is no way
to tell whether they are in sync. By contrast, new projects will always start with live netlisting on.
In either case you can switch according to preference from the live netlisting toggle on the Tools
menu in the PCB layout module.
