Multilayer .cpm file for Cadence 16.6

Hi,

I'm trying to learn Cadence PCB Editor Allegro GXL and Design Entry HDL 16.6. I searced for sample multilayer schematic and board files which are in same .cpm project, but i couldn't find. If you have any project file (.cpm-both schematic and layout files of same project in Cadence) or any idea and share, i will be happy.

Thank you
