Cadence heard you wanted some AI in your AI so it used AI to design an AI chip (www.theregister.com)

The idea of machines that can build even better machines sounds like sci-fi, but the concept is becoming a reality as companies like Cadence tap into generative AI to design and validate next-gen processors that also use AI.

In the early days of integrated circuits, chips were designed by hand. In the more than half a century since then, semiconductors have grown so complex and their physical features so small that it's only possible to design chips using other chips. Cadence is one of several electronic design automation (EDA) vendors building software for this purpose.

Even with this software, the process of designing chips remains time-consuming and error-prone. But with the rise of generative AI, Cadence and others have begun exploring new ways to automate these processes.

I remember an experiment in the late 90s where they had "AI" from then (fuzzy logic and some other tech) design EPROM chips that had to generate a very specific frequency, or something like that.

They ended up with 20 chips, and 20 different designs. They all worked, but...

Each one was programmed in a way that worked on that chip, and that chip alone. Copy the programming from one chip to another, and it would not work

Some chips had redundant circuits that connected to nothing, just sitting there. When those circuits were removed, the chip would fail too, even though those circuits in principe didn't seem to do anything as, again, they weren't connected to anything

Not a single one had an actual sense making correct solution

Basically the system just kept tweaking each chip until it guy something that worked

Current LLM's are more powerful but still operate in many similar ways. You can't ever trust them output so you'll have to check everything it does manually to get any remote kind of trust in the system, but how do you even go to test whatever random crap comes out on an AI chip?
