I am attempting to use Altium 18.1.9's new "Multi-Board" feature to connect a 200-pin SODIMM board ---> to a SODIMM socket connector ---> on my mainboard PCB. This Altium article is just about the only documentation I can find on how to go about doing this, and I don't think it explains what I need.
For the SODIMM board, I have created the schematic library symbol with all 200 unique pin names and functions. I have not created a PCB library footprint for this board, because I did not design the board, and I'm not sure I even need a footprint.
For the 200-pin SODIMM socket connector, I have created the schematic library symbol and PCB library footprint layout, which will connect (1) to (3). I added the "System: Connector" part parameter as shown in the Altium doc link above.
I have created my mainboard schematic (which includes the SODIMM connector), created the PCB, and placed the SODIMM connector footprint on it. Because of adding the "System: Connector" parameter in (2), I can see the connector in Altium's Multi-Board schematic project:
I am not sure what to do next. Should I create a new PcbProj just for the SODIMM board, add it to the PrjMbd, and define the SODIMM board as a "System: Connector"? Do I add another SODIMM socket to that project also?
I have no idea what to do next.
