All righty,

my distributors Altera FAE came thru and gave me a nice excel sheet he prepped for me. It basically shows you the I/O differences between all EP4CExxx in 484 pin packages. I added the common denominator column to it, so you know what you need to choose in order to be able to support all models of the package in question. Also I added a sheet for differential I/Os, there are a lot less possibilities. I had to rename most of them as pairs that are shared among different models rarely employ the same pin name combination.

Hopefully that'll help some poor FPGA designers and especially PCB layouters.

Please don't ask me for sheets for other families or packages, this one has taken me a few hours just for the diff-I/O sheet. But I guess you can use it as a template got others.
