Hi. May I know if the comments are preserved when using Verilog::Netlist. I tried comment command for Module/Cell/Net/Pin but it returns uninitialized in all cases.
I notice that keep_comments, include_open_nonfatal and synthesis options are commented out in Netlist.pm new class definition.
Please advise. Thanks
