Not really an HDL, as currently it has no concept of actually connecting the nodes. Each edge is an arbitrary number of conductors with no constraints on routing or timing. Curious to see where this goes though
> Although logic connectivity is not layout-dependent in the current prototype, we envision a future where physical proximity directly influences or determines logical connections. In this ultimate view, the circuit behaves like a digital organism whose physical form and logical connections evolve together under local structural constraints.
Once any HDL is translated to a bunch of primitives (gates, LUTs, flip-flops, etc), that's the job of an automated place-and-route, which already exist. It's independent of the starting language.
