<lkcl> whitequark: ping, i didn't realise, we have an entire EUR 8750 remaining, allocated for nmigen functionality and support for LibreSOC!
<lkcl> i'd totally forgotten about it.
<lkcl> you probably guessed, i'm doing a comprehensive review of bugreports today. how are things with cxxrtl?
jjeanthom has quit [Ping timeout: 264 seconds]
<lkcl> whitequark: star. i'll make a note of those. is there any "major showstopper bugs" which would prevent saying to NLnet "cxxrtl the basics is 100% done"?
<lkcl> lol will add those too
<lkcl> thx
<Sarayan> any recommendations on how a simulation of a Instance should be done to integrate with nmigen and cxxrtl?
<Sarayan> done as in implemented
<lsneff> not yet, it seems
<Sarayan> it's a very hard question, in fact
<lkcl> daveshah i *think* you mentioned very early on that you had managed, at the yosys level, to do a mixed ilang, verilog and vhdl cxx simulation?
<daveshah> No, that was only verilog and vhdl - I haven't tried with nMigen
<lkcl> ahh ok. well, it would be ilang. did you convert from verilog and vhdl into ilang to do that mixed test?
<lkcl> regardless, it's a good sign
emeb has joined #nmigen
<daveshah> no, I just used ghdl and read_verilog in the yosys script
<agg> i feel like this has been discussed before but couldn't find it, is there any way to force a fifo to use a bram? afaict you can't get at the storage in the fifo as it only exists inside elaborate, so you can't add attributes to it

<ktemkin> agg: IIRC typically you have to poke an attribute of its internal mem
<agg> How can you access it when it's only instantiated in elaborate?
<ktemkin> `<inner memory>.attrs["ram_block"] = 1` <-- Verilog/1364.1 attribute for that
<ktemkin> I'm not sure there's a clean way to do that
<whitequark> yep, not currently any way to do it
<whitequark> you can do it in the yosys script, perhaps
chipmuenk has quit [Quit: chipmuenk]
<ktemkin> probably wouldn't be too hard to tweak the API to add a clean way of adding attributes to said memory
<_whitenotifier-f> [nmigen] whitequark commented on issue #553: Failing Multidomain in CXXRTL - https://git.io/JILgf
<whitequark> it is actually not trivial to do
<_whitenotifier-f> [nmigen] whitequark commented on issue #553: Failing Multidomain in CXXRTL - https://git.io/JILgx
<agg> I just cranked the depth up enough to encourage it in the end, couldn't think of any non hateful way around it and not a huge deal
