jophish1Hi all17:09
jophish1I have some generated systemverilog code and yosys doesn't seem to like it very much17:09
jophish1It seems to choke here: https://gist.github.com/expipiplus1/a412cffa9a752a52eb7859f0390f6008#file-hdmi_types-sv-L4417:10
jophish1on `function`17:10
jophish1Specifically: `.build/clash/HDMITop.topEntity/hdmi_types.sv:44: ERROR: syntax error, unexpected TOK_FUNCTION`17:10
jophish1I don't know enough about SV to really be able to tell where the issue is17:11
FL4SHKjophish1:  you're using SV with yosys?  Really?17:14
jophish1oh, is this not a cool thing to do?17:14
FL4SHKtry sv2v if you want to use SV with yosys17:14
FL4SHKyosys's SV support is very poor17:14
jophish1I was using it because I have SV assertions set up17:14
FL4SHKah17:15
FL4SHKthat's valid17:15
FL4SHKif you're just using assertions, yosys is actually still limited, but it does support enough of that to get the job done17:15
jophish1although they're generated too, so I could probably set up a Verilog backend for them too17:15
FL4SHKI'm building something intended for use with yosys for formal17:15
FL4SHKit's a DSL to generate a VHDL AST17:16
FL4SHKcombined with the GHDL synthesis plugin, this should handle my needs in a language17:16
jophish1hehe, I had no end of trouble using GHDL for this!17:17

jophish1Worked first time! Thanks yosys :)17:56
