Logging level should be logging.NOTSET

332 | # instead of `logger.debug` outside of this function becomes an

333 | # error.

335 | if verbose:
336 | logging.basicConfig(format="%(levelname)s %(message)s", level=logging.DEBUG)

Calling basicConfig is unfriendly to other Python code that wants to use the logging as it cannot be called twice. If it must be called I think it should be called with logging.NOTSET

I bring this up because I have a custom log level set to 5 and I cannot see it.

The problem is utils.get_sim_time() is called to inject the current time into the log message, which calls simulator.get_sim_time(), which raises the RuntimeError.

@eric-wieser Calling default_config calls into the simulator. https://github.com/cocotb/cocotb/blob/26304cfc5fc9adbf567f2929910d5b6b9f414331/cocotb/log.py#L109-L110
