NotImplementedError: Unexpected object of type Error,

[SingaDK]

Hi,
I am trying to parse Ibex RiscV core, files, When I try to parse some files and export to JSON, I get this error

NotImplementedError: Unexpected object of type <class 'hdlConvertorAst.hdlAst._expr.HdlExprNotImplemented'>

The error line is

module ibex_alu #(
  parameter ibex_pkg::rv32b_e RV32B = ibex_pkg::RV32BNone
) (
    input  ibex_pkg::alu_op_e operator_i,
    input  logic [31:0]       operand_a_i,
    input  logic [31:0]       operand_b_i, ........)

"Ibex_pkg::rv32b" -> double colon.
I am using,

d = c.parse(filenames, Language.SYSTEM_VERILOG_2017, include_dirs, hierarchyOnly=False, debug=True)
from hdlConvertorAst.to.json import ToJson
import json
tj = ToJson()
j = tj.visit_HdlContext(d)
# pretty print json
print(json.dumps(j, sort_keys=True,
                 indent=4, separators=(',', ': ')))

There is no error in parsing the file. The error happens only on visit_HdlContext
I can get JSON out of most files in the core, but not files with the above-mentioned parameter definition.
Any pointers on this will be highly helpful.
Many thanks in advance.

Hello @SingaDK,
can you try installation of latest version from git?

pip3 install git+git://github.com/Nic30/hdlConvertorAst.git@master#egg=hdlConvertorAst --upgrade --no-cache
pip3 install git+git://github.com/Nic30/hdlConvertor.git@master#egg=hdlConvertor --upgrade --no-cache

It should be fixed, but I can not immediately do a new release because there is some problem with documentation:
sphinx-pyreverse/sphinx-pyreverse#20 (comment)
pylint-dev/astroid#930

And also circleci does not work today so the build seems to be failing, but it failed before the machine was even started from some circleci related problem.

Hi @Nic30,
Many thanks for the quick response and fix.
I tried the new installation. I am not getting that error anymore instead, I got more. The parsing itself throws so many errors like
It mostly with always ff, always comb, assertions, unique case

VerExprPrimaryParser.visitPrimaryAssig Conversion to Python object not implemented

VerStatementParser.visitAlways_construct.always_keyword` - non pure always Conversion to Python object not implemented

VerStatementParser.visitCase_statement.unique_priority`` Conversion to Python object not implemented

VerGenerateParser.visitModule_or_generate_item.assertion_item Conversion to Python object not implemented

VerModuleParser.visitModule_header_common - package_import_declaration Conversion to Python object not implemented

The file I am trying to parse is ibex_alu.sv.

Below I attached the full log of the error flow. Sorry for the long post, But many thanks in advance for looking into this.
