EDA claims in the digital domain are fairly easy to evaluate. Look at the picture of the layout.

When you see a chip that has the datapath identified and laid out properly by a computer algorithm, you've got something. If not, it's vapor.

So, if your layout still looks like a random rat's nest? Nope.

If even a random person can see that your layout actually follows the obvious symmetric patterns from bit 0 to bit 63, maybe you've got something worth looking at.

Analog/RF is a little tougher to evaluate because the smaller number of building blocks means you can use Moore's Law to brute force things much more exhaustively, but if things "looks pretty" then you've got something. If it looks weird, you don't.

That doesn't mean the fabricated netlist doesn't work. I'm not supporting Google by any means, but the test should be: Does it fabricate and function as intended? If not, clearly gibberish. If so, we now have computers building computers, which is one step closer to SkyNet. The truth is probably somewhere in between. But even if some of the samples, with the terrible layouts, are actually functional, then we might learn something new. Maybe the gibberish design has reduced crosstalk, which would be fascinating.
