I found your previous post - https://news.ycombinator.com/item?id=38170336
I find your ideas interesting, especially your strong interest in routing around any faults, but still ending up with a relatively usable compute fabric.
My approach is much, much simpler.... just a grid of cells, with the programming lines unspecified. Each cell has a 4 bits in from their neighbors, a 4x4 LUT, a latch on each of the 4 bits of output. Clocking on the latch is in 2 phases, like the colors on a chess board.... this makes everything deterministic, but fully Turing complete.
The fact that the logic does the routing means that you can route around anything at runtime. The homogeneity and simplicity of the fabric means the run-time libraries on the host computer could do that routing, provided it had a map of the defects.

I think the best approach is for both of us to try to get our ideas in the next Google open source chip shuttle.
