Automatic place and route on the board level is a neat problem to think about, but the practical usefulness is somewhat questionable. For 6U eurocard sized boards with sea of random MHz-ish SSI/MSI logic it makes some kind of sense, but who does that today. The board is either going to be so simple, that the placement and routing is obvious or so complex, that just even capturing all the constraints is more work than doing the layout mostly manually.
