I'm new to padslayout.There is a scenario in which I have to auto renumber and back annotate the file to the schematics which is in Dx-designer.
Before netlisting the schematics the REFDES of one of the component was U45 and after renumbering the PCB it is changed as U6.
The problem is that when I back-annotated the file in the Dx-designer, it shows the following error:
"Package U6 not found. "
Can anyone please explain why it happens and please give the solution to the problem??
