For the earliest details, see the press release from our DARPA project: https://juliacomputing.com/media/2021/03/darpa-ditto/ . This is being done in a way where a fully usable software is the result, so that those accelerations are not just a one-off prototype but a product that everyone else can use by the end. For more details, wait until next week's JuliaCon.
There's not really much public about it yet. There'll be a technical talk about it at JuliaCon and we're talking to initial potential customers about it, but it's not quite ready for the wider community yet. If you want some of the technical details, I talked about it a bit in this earlier thread https://news.ycombinator.com/item?id=26425659 about the DARPA funding for our neural surrogates work in circuits (which will be part of the product offering, though the larger product is a modern simulator + analog design environment, which is supposed to address some of the pain of existing systems with the ML bits being a really nice bonus).
Oh, I suppose I should add if you're looking to use something like this in a commercial setting, please feel free to reach out. Either directly to me, or just email info@ and you'll get routed to the right place.
