What software should be used to open PCB gerber and Assembly files for ADICUP360

Hi, 

I just downloaded PCB gerber files and Assembly files for ADICUP360.

(https://wiki.analog.com/resources/eval/user-guides/eval-adicup360/hardware/base_board)

These consist of *.art, *.drl, *.txt, *.ps, *.plt, *.cad files.

I used PADS, KiCAD for these files, but I failed.

What software should be used to open PCB gerber and Assembly files for ADICUP360 ?

Best regards
