BGA pin mapping

[RStump51]

I am trying to design a schematic for a BGA layout. I have the pins and their descriptions, but I don’t know how to represent it in Kicad.

Thanks

Do you know in general how the connection between footprint and symbol works in kicad or is this your first time looking into it?

A good starting point might be reading these two FAQ articles:

• What is the difference between footprints and symbols?
• How can i assign a footprint to a symbol?

Pin numbers for BGA’s usually have a letter and a number for row & column, just like a checkerboard.
Here I made a screenshot of an Olinuxino board

On my pc the board is in:
/home/paul/projects/kicad/OLINUXINO/HARDWARE/A64-OLinuXino/A64-OLinuXino_Rev_C/
You can also find it on github.

There are fairly automated scripts to generate schematic symbols.
I once saw a demo where whole columns of pins were copied from a PDF datasheet into a spreadsheet, edited a bit, saved and then an EEschem symbol created from the spreadsheet by a script.

But like Rene, it is not very clear to me what your question is.

Edit:

I have the pins and their descriptions,

You probably want to have a look at KiPart.
I did a bit of search magic and re-found the tutorial on Youtube.
The intersting stuff starts at about 8 minutes into the video.
@ 12 minutes into the video he starts talking about specific large pin count devices (such as BGA) and deviding pins over multiple schematic symbols.
