The parent comment absolutely has the LLM stench.

Appears? How so?

"The result: a design that passes simulation is far more likely to synthesize identically, averting costly back-end surprises"

This is the sort of phrasing that either a committee of marketing people wrote up, or an LLM.

> If you've ever been burned by Verilog's "works in sim, breaks in synthesis" gotchas

This is LLM phrasing. It's trying to be witty and relatable about an experience basically no person has ever had - or at least, those people being hardware engineers, they usually don't try to be witty and relatable in forum comments.

I don't know though, the comment as a whole doesn't feel AI-generated, but maybe AI-assisted.

Apart from the telltale direct paraphrasing of the Amaranth home page, the discourse about "works in sim, breaks in synthesis" can be regurgitated from any mildly disappointed essay about Verilog and feels plausibly AI-generated to me.
