How do I know that High Performance (HP) DDR/DDR2 controller has done calibration successfully?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You can ensure that HP DDR/DDR2 controller has calibrated successfully by writing data to the memory and read it back and comparing if it matches to the data written. resynchronization_successful going high or ctl_usr_mod_rdy signal going high does not mean that calibration was successful.

In the future version of the IP, resynchronization_successful will indicate successful calibration.
