My reading of this is that they asked the system to redesign the PCB that was used in the i.MX 8M reference system-on-module. It looks like they take a parts list, a PCB shape, and a rough floorplan and pass that to their tool, which spits out a PCB design.

I could actually see myself using this tool, as someone who trained as an EE and still likes to tinker with electronics. It would be fun to just assemble a parts list and a rough layout and then receive a working electronic device a few weeks later with minimal work.
