Why does the Timing Analyzer display data signals as base clocks in the Clock Network Viewer?

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 23.2 and earlier, you might see that the Clock Network Viewer in the Timing Analyzer incorrectly displays certain data signals as base clocks.

    This problem arises when the Timing Analyzer detects an SDC constraint defining a clock fans out to both data and clock ports. It is important to note that this behavior does not impact the timing analysis of the related paths.

    This problem only affects Intel® Stratix® 10 devices.

     

    Resolution

    It is safe to ignore clocks originating from data pins, as reported in the Clock Network Viewer.
