I didn't mean to infer that the final location of a part would be determined by the schematic, just the initial placement of parts in pcbnew when the netlist is first read. Similar to the spread out all components tool. A starting point. I can also imagine a tool that would try to minimise the

So it is already implemented in the legacy canvas: -Global spread and place -> Spread out All Footprints -Autoroute -> Automatically Route All Footprints Well, two clicks instead one just one. I'm with Wayne: no effort should be added to autorouting as there are plenty of features to sort

In many commercial tools you can use some or another feature to mark up the design at the schematic level with what components "go together". Then that information is used during PCB placement, the first-pass arrange of components when you start designing a board can place those components

In terms of automatically arranging components a force directed graph algorithm may work quite nicely, especially if the algorithm is seeded with the layout of components on the schematic. A simplistic version would be to just arrange components on board sheet as to their position on the

One thing that may be of more interest to board designers is an automatic footprint placement algorithm that minimizes the number of air wire crossings. Not so much to place the footprints but to orient them. A few years ago someone proposed using a chemical reaction stability algorithm where

Yes, I have also heard that from my hard-core board design colleagues. No one uses auto-routers anymore, they instead use interactive routers that have gotten very good lately. We should continue to push the KiCad interactive (PNS) router to add capabilities (multi-net routing, via array styles,

Actually the second point in that post is a gem (rerouting of tracks when you move a component) It is a feature of some super-high end packages (Xpedition, Allegro I think) but missing from lots of paid tools (Altium, Zuken, etc). It's on my list of things I want to add to KiCad at some point
