IP Product: RLDRAM II Controller with UniPHY

What are the local_cal_success and local_cal_fail signals of UniPHY-based memory controllers?


The local_cal_success signal is asserted when the memory initialization, training, and calibration completes successfully. The UniPHY-based controller asserts this signal coincident with local_init_done to indicate that the memory interface is ready for use.

The local_cal_fail is asserted by the UniPHY-based controller when the memory initialization, training, and/or calibration fails. The local_init_done signal will not assert when local_cal_fail asserts.
