whitequark: re wrapping SB_IO: I wrote that 6 months before nmigen emitted SB_IO, I expect I could probably get rid of it today
(though i am desperately looking forward to the upcoming documentation, I always get confused about how to use Pins in a platform and just have to read the source, especially for things like dir="-", invert, diff pairs, etc
The short, slightly-exaggerated version is wq got sick of dealing w/ various toolchains not inferring I/O primitives consistently, so now nmigen generates the I/O primitives directly.
oh yes, i think it's great
i wrote that whole project before nmigen.build existed at all iirc
later dropped most of my build code to use nmigen's
but there's still some stuff like manual sb_io floating around for iirc tristate ios or something
