alt Hacker NewsYeah, another way to say it is that the biggest inputs to any complex design aren't actually captured in the board files themselves. Everything you listed are system integration complexities that no level of autorouter will be able to accommodate for, and they make up 80%+ of the work.
While I agree they're not in the files, I don't think that's the correct root of the problem. Rather, given the LLM input assumption is that they are communicated, I think the key problem is that they can't be readily communicated because even the specifying party is unsure what they are. That is to say, it's a wicked problem. https://en.wikipedia.org/wiki/Wicked_problem
