I am contemplating my first BGA design with gEDA tools (AT91SAM9G45, Atmel ARM9). The part is a 18 x18 =324 ball device with row designators marked as A-V (missing I,O,Q,S,...). The Pin designators are labels K16, R2, G7, .. with the Alpha first, followed with the number. I tried to put in a pin label like this, but encountered problems with the online tool at (http://vivara.net/cgi-bin/djboxsym.cgi).
Has anyone been making BGA parts with multiple symbol files? If so, what do I need to look out for as I go down the development path? (Will multiple symbols process as multiple items on the BOM?, Will the netlister correctly pickup the different symbols. Can Alpha-number designators be used at all?
