Multiple PCBs from a single project/schematic

markshancock

We have a muti-board system that uses 13 boards connected using board-to-board connectors.

Presently this means 13 different projects each with their own schematic and pcb design.

While this makes PCB fabrication easier, it makes following a signal trough 13 different schematics very difficult and people are complaining.

 

One solution idea was to combine all the schematics together on a single large sheet so it is easier to follow. 

We would have to be careful with signal names (esp power and ground) to make sure the nets stay isolated; but, I believe it is doable.

The question is, if we ca do that, could we then route all 13 separate PCBs using that one schematic?

 

If so, what would the challenges and limitations of doing that?

Has anyone done this before?

    Why combine these at design level? Im sure there is a tool to combine

    several prints into one sheet. I assume you will need a printing

    house to do that job, and I'm sure they can help.

     

    But I do see some advantage maintenance, but only if the 13 designs have

    much in common.
