And I certainly can't imagine how a language model would be of any use here, in a problem which doesn't involve language.
They are "okay" at generating RTL, but are likely never going to be able to generate actual bitstreams without some classical implementation flow in there.
I think in theory, given terabytes of bitstreams, you might be able to get an LLM to output valid designs. Excepting hardened IP blocks, a bitstream is literally a sequence of sram configuration bits to set the routing tables and LUTs. Given the right type of positional encoding I think you could maybe get simple designs working at a small scale.
