Change no-ERC symbol and note in IC9
From what I remember, the CERN symbol for IC9 (PS2065DGN) defines pins 6-8 as outputs while they are used as power, and to avoid ERC errors, the ignore symbol is used.
It might be confusing and I received questions about this during the review. So I asked how such situations are handled in other CERN designs.
I propose the following updates
- change the no-ERC symbol to a "more friendly", e.g. a tick - this is done in other CERN designs
- update the existing note to be more clear and say: "This symbol is defined in CERN library with pins 6-8 as outputs while in this design they are used as power. To prevent Altium complaining, no-ERC marker is used."
