How the synchronizer associates the schematic and PCB components
When a schematic and its PCB have been synchronized, matching schematic and PCB components are assigned a matching identifier. This approach means that you are free to separately re-annotate the schematic or the PCB. They can be bought back into harmony at any time by running an Update from the design menu.
If a component without a matching identifier is found in either the schematic or the PCB, the synchronizer attempts to find a matching component for it. These matches are shown in the Confirm Component Associations dialog, which automatically appears whenever unmatched components are detected by the synchronizer.
The synchronizer does this initial match by designator, always check that the matches are correct. When you click on the Apply button the matched components will be given a matching ID.
If the Update is from schematic to PCB, the unmatched reference components are added to the PCB and the unmatched target components are either removed or reported, depending on the Components option in the Update dialog.
If the Update is from PCB to schematic, the unmatched reference components are listed in the Preview Changes Report, and the unmatched target components are either removed, or reported, depending on the Components option in the Update dialog.
