My own feeling is that you can't really automate design, because it's intuitive and non-linear. Programmers supply the tools that make it quicker to communicate and verify the features of the design but the design comes from inside. The tools aren't creative and they don't organize the effort; their main purpose is documentation and the associated communication.
