stackup - the stackup is generally a print or written description of the board material, thickness, interposer and order. IPC-D-356 - esentially an electrical database of connections needed for testing the completed board.

It is a very old format with a couple of variations and contains net names, test points and pins.

The great majority of PCB design software (layout) can output a valid and correct ODB file.
