Fatal Error: Read data comes back but dynamic OCT ctrl is not in read mode

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You may see the following error when you simulate the UniPHY based DDR3 controller in full calibration mode.

# ** Fatal: Read data comes back but dynamic OCT ctrl is not in read mode

Resolution
  1. Open the following file in your simulation file-set: altdq_dqs2_ddio_3reg_<user_device>.sv
  2. Find the following line: (1, "Read data comes back but dynamic OCT ctrl is not in read mode");
  3. Replace the line above with the following line: ("Read data comes back but dynamic OCT ctrl is not in read mode at time %f", );

The simulation should run without any errors once the above change is implemented.
