The first step in determining the calibration status is to check the status of init_calib_complete and calib_error signals. The init_calib_complete only asserts if calibration passes successfully, otherwise calib_error is asserted. Calibration halts on the very first error encountered.

There are three status registers, cal_passed_stages, cal_failed_stages, and cal_skipped_stages that provide information on the successfully completed calibration stages, the failed stages, and the skipped stages, respectively.
