@jimbob there are but HDL is the closest to being "open". EDA tools will come with a language too, but I dont know if there's a standard. Generally it's used for simulation or "debugging". From what I've seen, LLMs only really know JavaScript. They'll write other languages, but really they're trying to write as JavaScriptey code as possible. They don't abstract or modularise. Someone I know called them a "word calculator" and that's pretty close. A word calculator which makes mistakes.
