But its still such a complex sort of beast.

Even if you had 'ai tools' guessing at component blocks on evaluation you would have to have some evaluation of the result.

And, thats assuming NVDA hasn't pulled a Masatoshi Shima type play on their designs (i.e. complex traps that could require lots of analysis to determine if they are real or fake)

Im not sure how much of a speedup even modern tooling/workflow could do reliably.

Even then,

The elephant in the room is that China is working on their own AI accelerators/etc, so while there can be benefit from -studying- the existing designs, however I think they do not want to clone regardless.

Oh, absolutely. Straight up soviet style cloning of masks makes no sense for multitude of reasons. In addition to what you've said, China isn't banned from N7 class Nvidia architectures so could just buy those on the open market.
