No, Google's AI is floorplanning[0] (basically routing and layout) human-designed logic in 6 hours. That headline is misleading.
It's kind of like having a compiler will billions of optimization flags and using AI to select a pretty near-optimal set of flags for a particular human-generated source file. We wouldn't call the output an AI-designed program, even though such AI would be really helpful.
Google is using AI as a heuristic for decently fast approximate solutions to the floorplanning problem, where (IIRC) optimal solutions are NP-hard.
It's an important step forward, and presumably a big time saver, but they're nowhere near giving the AI an instruction set spec or examples of inputs and outputs ad having the AI generate the logic.
