Why do I get sdc warning messages regarding altpcie_ltssm_fifo.sdc and altpcie_link_inspector.sdc, when compiling designs which instantiate the Intel® Stratix® 10 Hard IP for PCI Express* IP?

Environment

  • Intel® Stratix® 10 FPGAs and SoC FPGAs
  • Intel® Quartus® Prime Pro Edition
  • Avalon-ST Intel® Stratix® 10 Hard IP for PCI Express
  • Avalon-MM Intel® Stratix® 10 Hard IP for PCI Express
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition software version 18.0 and 18.0.1, you may see some sdc warning messages when compiling a design which instantiates the Intel® Stratix® 10 Hard IP for PCI Express* with the Link Inspector enabled. These warnings are related to the Intel® Stratix® 10 Hard IP for PCI Express* IP core sdc files: altpcie_ltssm_fifo.sdc and altpcie_link_inspector.sdc.

     

    Here are some of the compilation warning messages:

    Resolution

    To work around this problem, upgrade your design to Intel® Quartus® Prime Pro Edition software version 18.1. If you cannot upgrade your design, then replace the following files with the files provided in the link below.

    <your pcie instantiation path>/altera_pcie_s10_hip_avmm_bridge_180/synth/altera_pcie_s10_link_inspector/altpcie_ltssm_fifo.sdc

    <your pcie instantiation path>/altera_pcie_s10_hip_avmm_bridge_180/synth/altera_pcie_s10_link_inspector/altpcie_link_inspector.sdc
