11.6.2. Hardware and Calibration Issues

Hardware and calibration issues have the following definitions:
  • Calibration issues result in calibration failure, which usually causes the emif_fm_0_status_local_cal_fail signal to be asserted.
  • Hardware issues result in read and write failures, which usually causes the pass not fail (pnf) signal to be asserted.
Note: Ensure that functional, timing, and signal integrity issues are not the direct cause of your hardware issue, as functional, timing or signal integrity issues are usually the cause of any hardware issue.
