I would say that the design is to include the design of the pieces that are supposed to be produced by the manufacturer rather than to be bought. A better example is coils rather than chips: people may buy them or make them themselves; when the designer intends to make the coil, its design should be included (at least, the instructions on how to make it); when it's to be bought, it's sufficient to specify its features needed to get the right coil. > > The layouts for a device is typically harder to make than its > > schematics; the gerber files (technically, gerber + drill files) > > are made automatically from the layout in its source code form. > > This suggests that a complete design for a board should include the > layout.

I believe so, it just could be convenient like including PDF and DVI versions of the documentation written in Texinfo. > (Is there free software to generate them?) These files are typically generated by the same program that is used to draw the layout (like "Export" in GIMP).
