Good idea.

Well, I just followed the OM schematics, that is the only reason actually. What's the impact of omitting them on the symbol?

I'm to rename all components in this sheet to 8xxx. I'll ensure mapping (in an ECN) will be correct then.

Well caught, thanks.

They all will be renamed, as previously stated.

That was something I asked a while ago. We are not using these shielding points in any other sheet, are we ?

Sure we do, but this allows you to switch from one to another quickly. So if you just want state-of-the-art design plus the old daugherboard, just change the
project file.
