I had Opus 4.5 design an LLM inference engine in verilog, including firmware and automated verification a while ago: https://github.com/cpldcpu/smollm.c
It's of course far from optical. But lowering the implementation through the abstraction levels turned out to be extremely powerful.
Can you suggest some tutorials for Verilog and FPGAs in general?
I have a spare Tang Nano 9k but I don't feel confident about blindly asking Claude to vibecode me a solution and still would like to have at-least a basic level of understanding.
hm.. has been quite a while for me. The good thing about the Tang Nano is that it is supported by the Yosys open source toolchain. There are quite a few resources on the web when you search for the combination.
