Why is the "Additional CK/CK# phase" option grayed out inside the MegaWizard GUI for the Stratix V device?

Environment

  • Quartus® II Subscription Edition
    • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description The "Additional CK/CK# phase" option is grayed out in the MegaWizard™ GUI because custom phase shifts for the memory clock is not supported for that device and protocol. The Stratix® V and Arria® V GZ devices only support this option for UniPHY-based DDR2 memory controllers with a frequency of 150MHz or above.
