Do you have already build MK64 XFBGA schematic for Altium ?
Or should i build it from zero ?
Freescale offers CAD symbols through an tool which I use for Eagle CAD, but I see it supports Altium too.
Have a look here for more information:
Freescale Kinetis CAD Footprints and Symbols for Eagle/Altium/etc | MCU on Eclipse
I hope this helps,
