Hello, I encountered a problem when reading a Systemverilog package with Yosys. Error message is as shown below:

2. Executing Verilog-2005 frontend: ./designs/src/opentitan_soc/ip/prim/rtl/prim_util_pkg.sv
./designs/src/opentitan_soc/ip/prim/rtl/prim_util_pkg.sv:28: ERROR: syntax error, unexpected TOK_FUNCTION

And the part of the code it is complaining about looks like: (line 28 is the 

function automatic...

)

function automatic integer _clog2(integer value);
    integer result;
    integer v = value;
    v = v - 1;
    for (result = 0; v > 0; result++) begin
      v = v >> 1;
    end
    return result;
  endfunction

Is it because Yosys has yet to support Systemverilog functions in packages?

Hi Everyone, is anyone able to synthesize systemVerilog using the latest of Yosys? Either way, what do you guys do and which sv2v tool work for you? @User @User @User

@Ke-Haur Taur make sure this package is not declare in a generate block of verilog.

@Zeeshan Rafique No that function is not in a generate block And it is not imported in a generate block either. The error was thrown before Yosys got to the files where it actually used the package. Yosys stopped parsing that package due to the

function

construct which is only supported by the latest build I think

Is it independent of any block?
