Flux.ai being the incumbent Silixon based out of the UK have been showing demos Quilter and DeepPCB for layout The recent OpenAI demo...

I went the other way and pre-designed sub circuits with a set of rules that allows simple merge assembly, unfortunately I didn't have the time or budget to continue with it, but I took the constrained approach as with hardware, things can't be 99%.

The one thing I will say, is that my experience of hardware engineers is very gatekeepy.

Any questions about the use of AI for any form of automation on forums/Reddit get shot down instantly and the OP's told 'skill issue' more or less. In my opinion, just as with software, most work is simple and should be automated, there will always be a need for the real engineering when it comes to high specification work, high volume optimisation and hardware debug (although Claude code is pretty handy at driving a Jlink)
