Auto-routing software might be the closest thing to AI.
I read that computers have the task of designing computers nowadays (probably in the sense that a human would not want to draw and re-draw so many complex microscopic circuits, including memory cells which are duplicated many times on a board).
Today we have 'expert systems' which are like a search engine with access to one or more encyclopedias about a field of knowledge. The internet is almost similar, because we can type in a topic, and a few parameters, and quickly find articles and schematics and calculators.
