Press "Back Annotate" button in Expedition.
There are (2) ways to do this from within Expedition:
1) Setup>Project Integration
A GUI will pop up and there are 4 options ( 4 buttons that will either be green or amber), 1 of which pertains to the PCB changes to be back annotated - Select the last option. It will tell you "Back Annotation Required" if there are changes that have been made i.e. pin swaps or ref des updates and the color will be amber letting you know an action is required.
If nothing has been changed, no action is required and it will say "No pending PCB changes to be back annotated. (The color will be green)
2) ECO>Forward Annotation
Select this option and it will back annotate, but it does show any of the options above it will just state that back annotation completed successfully.
Either way you go it will update any changes made in Expedition to DxD
Also, you can use the BackAnnotation.txt log file to see what changes were made if any. It will also track the LogicDB versions as the design evolves and changes are back annotated to DxD. (This file is located in in the PCB folder under LogFiles
Below is an example of the log file --> I changed 1 ref des and swapped 6 pins and you can see that it states this in the log file.
