Why does IOPLL Reconfiguration fail to work correctly when using Intel® Stratix® 10 devices with Intel® Quartus® Prime Pro Edition software version 19.3 or later?

Environment

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

    Due to a problem with Intel® Quartus® Prime Pro Edition software version 19.3 and later, reconfiguration of IOPLL IP with the IOPLL Reconfig Intel® Stratix® 10 FPGA IP may fail to work correctly when using Intel® Stratix® 10 devices.  You may find that, after a reconfiguration request, the IOPLL does not get reconfigured.

    Resolution

    To work around this, compile your design using an IOPLL IP file from Intel Quartus Prime Pro Edition software version 19.2. 

    This problem is fixed starting from Intel Quartus Prime Pro Edition software version 20.4.
