Stratix 10 SerialLite III Streaming Design Example unable to compile due to fPLL error.

Environment

  • Intel® Quartus® Prime Pro Edition
  • Serial Lite III Streaming Intel® FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    When using the Stratix® 10 SerialLite III IP core Streaming design example, the following fPLL error may be seen for depending on the transceiver reference clock frequency is being used.

    Error: altera_sl3_fpll.altera_sl3_fpll: Violating K limits for auto mode. The most common occurence of this error is when refclk and output frequency combination can be synthesized in integer mode and user has selected fractional mode.

    Resolution

    To work around this issue, manually modify and regenerate the altera_sl3_fpll.ip file.

    Using Qsys open and edit the example design FPLL file located in:

    \ed_synth\altera_sl3_fpll.ip

    de-select "Enable fractional mode" option, re-generate the IP and re-compile.

    This problem will be fixed in a future release of the Quartus® Prime software.
