Because I'm moving a design from a different Spice simulator/schematic package I have 4 schematic diagrams that must be integrated onto, and connected on a single PCB. I started this process some time ago, but now need to update some of the schematics because component have been replaced due to obsolescence. I have a project for each schematic, and a PCB layout in each too, but some were saved as modules so that they could be added to the master PCB for final layout and connection work. How can I tell which of the PCB layouts are modules?
