I am unfortunately only SW-engineer and from my limited understanding of the HW side I got that (among others) the WASP team was in direct contact with Bitmine and clarified remaining issues. With that, IIRC a revised spec was released that the teams found sufficient enough to design with. If that is not the case, please let me know or post open topics here.
As for the reference design, I remember there is a design contest planned, but it seems Bitmine is too busy with development to announce it in time. I will check status and report back.
You wrote what we will get... Now it is a bit unclear so you could say this is this and not what you thought you will get but...
Chip specifications, design documents, reference software, and everything that is required to design mining rig development will be provided through github incrementally, with a guaranteed availability of all required support material by end of October.
We have chip specifications... Now unless design documents is not some reference board design but document of the chips there is noting there... And since we are talking about reference software I guess it is for design documents board. Right? So that is missing too. So is this document all we will get? I though Bitmine will follow Avalon and BFL way of doing things. We could probably do with just this document but not in a time frame for first chips...
EDIT: and probably took board or two to get it right...
The document is all what Bitmine has available for their own design - if you miss something, please name it. You can not compare this to Avalon or BFL - they had already a working design that only needed to be published. Here everybody starts with a chip still in pipeline and there is no single design proven to work around to be named as reference - if you want to compare it, you need to do so with BitFury chips.
Again, I do not know how much is required to enable HW designer to work on a PCB for this chip, but since the WASP team is almost done, I have to assume it is sufficient. Please let me know otherwise which exact information you miss.
It is enough if you have a lot of time and some luck... And I wasn't compeering chip but the way they did it... Giving us schematics firmware and gerber... Enough for crating a clone with minimal effort... I'm sure Bitmine has to have something since they are selling miners too... If we don't see that there is no way we can be close to sure we have more or less working board ready for chips...
