Why is the clock not running in my design when I use the Clock Control Intel® FPGA IP?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.2, you might see the clock which input to the Clock Control Intel® FPGA IP is not running. This problem occurs when you enable the Clock Enable feature in the Clock Control Intel® FPGA IP and drive the ena port low.

    This problem only affects designs targetting Intel® Stratix® 10 or Intel Agilex® 7 devices.

     

    Resolution

    To work around this problem, set the "Clock Enable Type" in Clock Control Intel® FPGA IP to Root Level.

    This problem is fixed beginning in the Intel® Quartus® Prime Pro Edition Software version 22.3.
