These are being made by Dialog and looking at the tools appear to be a relative of the GreenPAK devices. They were essentially very very small mixed signal programmable logic devices but the data sheets detailed every bit in the bitstream. With any luck these new parts will be the same. They are already using Yosys for synthesis.
Oh that's some nice info, with their low price point (around 0.25$ for the low-end ones) the GreenPAK devices appeared to me like a gamechanger in the making. I hope they gain more traction in the future.
Exactly, but I've given up on hardware companies ever making a good software product. I think that hardware companies are full of hardware engineers who made a little Javascript app once, and who assume that making software is easy. And they promote from within, so suddenly your software team is run and operated by people who made a Javascript app once.
