Why does the Quartus II software not issue a warning message concerning jitter when a PLL is not driven by its dedicated clock input pin for an Arria V device?

Environment

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

    Due to a bug, current versions of the Quartus® II software will not issue a warning message concerning jitter when a PLL is not driven by its dedicated clock input pin.

    Resolution

    The warning that you should receive in the Quartus II software is:

    Warning (15055): PLL "<PLL Name>" input clock inclk[0] is not fully compensated and may have reduced jitter performance because it is fed by a non-dedicated input

    This issue is scheduled to be fixed in a future release of Quartus II software.
