Испытательный файл не найден с использованием NVC с Cocotb [закрыто] ⇐ Python

[Anonymous]

Я пытаюсь сделать вспомогательную функцию, чтобы запустить тест Cocotb следующим образом: < /p>
def run(hdl_toplevel: str,
test_module : str,
work_dir : str,
root_dir : str,
parameters : typing.Mapping[str, typing.Any] | None = None
) -> None:

log_enable = True

# Prepare working directory.
work_dir = pathlib.Path(work_dir + ".work")
if work_dir.exists():
shutil.rmtree(work_dir.as_posix())
work_dir.mkdir(parents=True)

# Prepare root directory.
root_dir = pathlib.Path(root_dir)

# Pull configurations from yaml.
runner_config = config.CONFIG['runner']
runner = cocotb.runner.get_runner(simulator_name=runner_config['simulator']['name'])
#print(f"Using simulator: {runner_config['simulator']['name']}")
sources = [cocotb.runner.VHDL(str(path)) for path in
itertools.chain.from_iterable(root_dir.glob(source) for source in runner_config['vhdl_sources'])]

# Build the HDL using the cocotb runner.
runner.build(
hdl_library = runner_config['hdl_library'],
sources = sources,
build_args = runner_config.get('simulator').get('args', []),
build_dir = work_dir,
hdl_toplevel = hdl_toplevel,
log_file = work_dir / "build.log" if log_enable else None,
always = True, # Always run the build step
waves = True, # Unfortunately, waves is not yet supported, using the cocotb.runner. Waves can be generated with the Makefile approach, however.
)

# Run the test with cocotb runner.
runner.test(
test_module = test_module, # Python module(s) containing the tests to run
hdl_toplevel = hdl_toplevel,
hdl_toplevel_library = runner_config['hdl_library'],
hdl_toplevel_lang = "vhdl",
test_dir = work_dir,
log_file = work_dir / "sim.log" if log_enable else None,
parameters = parameters
)
< /code>
Я получаю эту ошибку: < /p>

Я использую NVC в WSL. И я запускаю его, используя Pytest и использую метод Cocotb Runner, как это: < /p>
runner.run(
hdl_toplevel = "axiLite_reg_top",
test_module = "test_axiLite_reg",
work_dir = str(Path(proj_path / "axiLite/sim/cocotb")),
root_dir = str(Path(__file__).parents[3]),
parameters = None)
< /code>
Я попытался имитировать VHDL с NVC, чтобы убедиться, что ошибки нет, и он уточняет и работает правильно. Также при использовании cocotb.runner напрямую он работает нормально.
