00:50 <_whitenotifier-a> [YoWASP/yosys] whitequark 6e99283 - Update dependencies.

03:22 <d1b2> <4o> that's a very soft bug report. i've been seeing such messages while pysim: "fakename:46: DriverConflict: Signal '(sig $signal)' is driven from multiple fragments: top.crc, top.rx_decoder; hierarchy will be flattened". restarting the sim fixes it

03:22 <whitequark[m]> what is the bug?

03:23 <whitequark[m]> i.e. what do you expect to happen and how does restarting the sim help?

03:25 <d1b2> <4o> sim fails when this is reported. i'm running hundreds of unit tests in a batch. i see this like 1 time in ~10-20 runs so error rate <1/1000. dont have more info, just this symptom now. hard to get info as it's not that easy to reproduce

03:26 <whitequark[m]> interesting

03:26 <whitequark[m]> yes, that is definitely a bug

03:26 <whitequark[m]> a small repro would be most welcome, even if it's not fully deterministic

03:26 <d1b2> <4o> i'll try to pin it down

15:30 <mithro> whitequark[m]: did I ever share http://cfu-playground.rtfd.io/ with you?

15:30 <mithro> I would be very interested in seeing that approach for optimising wasm execution on something like the Fomu...

15:31 <whitequark[m]> yeah you did
