Why does 25G Ethernet IP's dynamic generated example design fail timing in Intel® Stratix®10 FPGA ES1 and ES2 devices?

Environment

  • Intel® Quartus® Prime Pro Edition
  • 25G Ethernet Intel® FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    Due to a problem in Intel® Quartus® Prime Pro Edition Software version 18.0, the 25G Ethernet IP's dynamic generated example design may fail timing closure.

    The affected variants are as below:

    • 25G with IEEE 1588 Example Design
    • 10G/25G with IEEE 1588 Example Design
    • 25G with IEEE 1588 Example Design and RSFEC
    • 10G/25G with IEEE 1588 Example Design and RSFEC

     

     

    Resolution

    Launch Design Space Explorer II and perform seed sweep to get the best quality of fitter placement as the Intel® Stratix® 10 FPGA timing model is still at the preliminary stage pending engineering characterization.
