mewtis there any reasonable way to view a schematic for your yosys output, similar to what Vivado produces?15:21
mewtguessing not, but curious15:21
mewtshow runs for...a very long time, something like 9 hours now15:21
jixshow is the only thing we have, for anything that's not tiny you need to use the selection argument to select a smaller part of the design for it to be useful though15:25
jixthe limitation here is what graphviz (which show uses) can layout in practice15:26
mewtright15:28
jixthere's also https://github.com/nturley/netlistsvg which uses the eclipse layout kernel instead of graphviz, that seems to produce a more schematic like layout than graphviz, but I have never used it and have no idea if it scales better or worse15:28
mewtthanks for the answer, I guess I can either select or just look at another way to troubleshoot my design15:29
jixsomewhat cursed alternative: export the design as structural verilog (write_verilog -noexpr) and load it into vivado (no idea if that would actually give you a usable schematic view)15:31
mewtYeah, I think there's gotta be a better way to do what I'm doing. This was just a potential debugging method15:33
jixoften I end up using running `show foo/bar %ci2; show foo/bar %ci4; show foo/bar %ci6; ...` to see the input cone of a signal bar in module foo with an increasing depth limit15:36

FL4SHKhey... thanks for the great tooling!19:11
FL4SHKIt is helping me prove my design19:11
