[nmigen] adamgreig opened issue #34: Unexpected Memory behaviour in simulation - https://git.io/fhyHX
<sb0>
mmh the ddmtd on rtm worked fine for a while yesterday, but now I'm just getting random values out of it :(

and now it works again, for no reason
<sb0>
when it does work, it seems to work well though. less jitter than ultrascale.
<sb0>
all other alignment procedures and tests also pass
<sb0>
running a reboot loop for a few hours ...

whitequark: any news about nMigen builder system ? have you made your choice ?
<cr1901_modern>
key2_: It's likely going to be edalize
<cr1901_modern>
afaik
<key2_>
yeah i heard about it
<key2_>
Then we still need the platform
<key2_>
as this is one of the good thing of migen

sb0: you mentioned Sayma config from kernels a few days ago
<hartytp>
isn't the current 12s boot time heavily bloated by diagnostics that we won't keep forever
<hartytp>
so it will be much less of an issue once we trust the hw a bit (or, at least the diagnostics can be disabled by default)
<hartytp>
but I take the basic point that for a large distributed system it's nice to do as much of the bring up locally
<hartytp>
however, it would be nice to have access to the DAC SPI bus from kernels
<hartytp>
for debugging etc
<hartytp>
e.g. I can imagine wanting to play around with the DAC registers from my experiment to test things out or change config dynamically (enable mixer mode or something like that)
<hartytp>
another case being reading the DAC temperature using its internal sensor. which is something I'd really like for measuring phase stability
<hartytp>
is there an easy way of having the DAC connected to a non-realtime bus that can be accessed from either kernels or satman?
