03:44 <zignig> whitequark: I am a victim of my own automation , old code still works fine.

03:44 <zignig> whitequark: so my question becomes , how would you go about attaching a CSR mplex to the Boneless external interface.

03:45 <zignig> the once cycle delay in fetching the shadow register value seems to make the boneless get the value _next_ read.

03:46 <zignig> currently I have bus->[comb]->CSR and then [sync]-> to the Elaboratable.

03:48 <whitequark> I'm going to look at it closely after I clear the current backlog of issues

03:48 <whitequark> it'll take a bit of time though

03:51 <zignig> whitequark: no problem, I thought I was going crazy debugging this issue , GKTwave and a big screen to the rescue. ;)

03:52 <zignig> when you have some boneless time , it would be cool if we can merge tpwrules new instruction set too. :)

03:53 <whitequark> yeah

03:54 <tpw_rules> :3

20:55 <MikeP> Hi folks, I've been really enjoying learning nmigen, and came here in hopes of answering a question I couldn't figure out from the source.

20:55 <ZirconiumX> "don't ask to ask, just ask" is a motto of mine

20:55 <MikeP> I'm trying to get something to happen on the negative edge of the default clock domain

20:56 <MikeP> First dumb thing I tried was: m.domains.neg = ClockDomain("sync", clk_edge="neg", local=True)

20:56 <MikeP> but (in simulation at least) the "neg" signal stays at 0

20:57 <MikeP> Is there a way to do this?

20:59 <ZirconiumX> MikeP: Judging by the docs, your code is overwriting the `sync` domain

20:59 <ZirconiumX> Because the "sync" there is not the source clock but the clock name

21:00 <MikeP> fwiw I also tried ClockDomain("clk", clk_edge="neg", local=True)

21:01 <ZirconiumX> Hmm

21:01 <ZirconiumX> ClockDomain(m.d.sync, clk_edge="neg", local=True) maybe?

21:02 <ZirconiumX> It's asking for a Signal, not a string

21:02 <ZirconiumX> ...I'm getting it mixed up with the clk attribute

21:03 <ZirconiumX> Actually, what if we just leave it at the default and let nMigen figure it out

21:05 <ZirconiumX> MikeP: So, I think you're overwriting the sync domain with an undriven clock domain, which is why nothing happens

21:05 <MikeP> btw which docs are you looking at?

21:05 <ZirconiumX> https://github.com/m-labs/nmigen/blob/master/nmigen/hdl/cd.py#L17

21:05 <ZirconiumX> The source itself

21:05 <MikeP> (and thanks for looking at this)

21:06 <MikeP> ah gotcha

21:06 <ZirconiumX> I think you'd need to supply a clock to `clk`, but I don't know how to do that at present.

21:11 <MikeP> I originally got the idea for how this might work from Robert Baruch's tutorial here: https://github.com/RobertBaruch/nmigen-tutorial/blob/master/3_modules.md

21:11 <MikeP> The section "Tip: clock domains with the same clock but different edges"

21:13 <ZirconiumX> Possibly something for whitequark when she's around
