dormitoI've notice that when I do "read_verilog -sv ${verilog-source-file}" it prints "Executing Verilog-2005 frontend", and then seems to choke on any usage of interfaces (says the signals implicitly defined, eventhough it already parsed it in the module ports). Am I invoking systemverilog incorrectly?07:59
Sarayanthe current sv parser has limits08:10
dormitothe README.md says it supports interfaces and mod ports... is that qualified or incorrecT?08:12
SarayanI'm not entirely sure of the limits, I know one is missing non-packed structures08:16
Sarayanbut I'm certain it's not yet fully handling sv-for-synthesis08:16
dormitoHmmm maybe the readme should be updated then (since it seems to pretty clearly say some certain systemverilog features are supported). I've distilled the reproduction down to a 23-line hdl file anyone wants to see how to invoke it.08:21
Sarayanwould probably be interesting to implement what's missing in that area08:24
Sarayanas far as I can tell it's a case of "nobody has implemented it yet", not something deliberate :-)08:24
dormitowell, if anyone's interesting. The trivial reproducer I created is here: http://dpaste.com/6XUPYP9UA/08:41
