Pin Function Grouping Request

Thought for 21 sec

flux

Yes — a pin should not be duplicated across groups.

For this workflow, each pin gets:

exactly one Section such as Power, Ground, GPIO, Communication, Analog, Clock, Control, Debug, or No Connect
exactly one sub-symbol grouping when the IC is split into multiple symbol blocks; the rule is that every pin must belong to exactly one sub-symbol

So if I group the pins for you, I would do it like this:

Grouping rule

Table

Case	How I would handle it
`VDD_1`, `VDD_2`, `VDDIO`, `3V3_*`	Put each pin once under Power
`GND_1`, `GND_2`, `VSS`, `AGND`, `DGND`	Put each pin once under Ground
`USB_DP`, `USB_DM`	Put each pin once under Communication with pin group `USB`
`SPI1_MOSI`, `SPI1_MISO`, `SPI1_SCK`	Put each pin once under Communication with pin group `SPI1`
`PA0`, `PA1`, `PB0`	Put each pin once under GPIO with pin groups like `PA`, `PB`
`RESET`, `BOOT0`	Put each pin once under Control
`NC`	Put each pin once under No Connect

Important nuance

A pin can have:

one Section for its main function
one Pin Group for its family/prefix

For example:

SPI1_MOSI
- Section = Communication
- Pin Group = SPI1
PA3
- Section = GPIO
- Pin Group = PA
GND_2
- Section = Ground
- Pin Group = GND or Ground depending on naming convention

That grouping method is explicitly recommended: sections classify the broad function, while pin groups collect related pins by shared prefix like PA, SPI1, USART2, USB, etc.

So your expectation is correct:

I should not list the same pin in both Power and Communication
I should choose the pin’s primary/common function
then place it in one functional group only

If you want, I can now produce the actual grouped list for the Apollo510B in this exact format:

Apollo510B pin groups

Table

Section	Pins
Power	...
Ground	...
GPIO	...
Communication	...
Analog	...
Clock	...
Control	...
Debug	...
No Connect	...

And I’ll make sure each pin appears once only.
