Unfortunately not all pins in the pinout files have unique names - many are just named "IO" together with the package-specific pin (i.e. "T8"). I need the information where the pins are internally connected to, e.g. the name of the respective I/O cell or something like that. In the pin planner I can see additional columns:

- X coordinate (0..41)

- Y coordinate (0..29)

These values seem to designate the location on the die. Can anyone confirm?
