I really need an explaination about the reference designator as shown in this topic: https://support.mentor.com/en/product/852852099/knowledge-base/MG80631
1) Why for some components, there is this problem and for others, there is no problem? For the moment I have this problem only for CAPACITOR...
2) I followed the topic in the goal to change the ref des.
- For the first capacitor on my design, no problem with the 2 methods.
- For a second reference, it's impossible for me to change the ref des of this capacitor... I deleted the "C?" on the symbol editor, package with "Delete local data, then rebuild all local lib data" but the ref des still "U145" instead of "C145".
Thanks for information.
