Error(21843): Rule: gdrb_gdr_pcie_ip16::pf0_pci_msi_64_bit_addr_cap_rule @ gdr.z1577b.u_pcie_ss.u_ctop.ub_core16

Environment

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

    Due to a problem in the Quartus® Prime Pro Edition Software version 22.4 and earlier, the compilation error above occurs when the Multi-Channel DMA FPGA IP for PCI Express* is configured with the "Enable MSI Capability" parameter disabled and "Enable MSI 64-bit Addressing" parameter enabled. Both of these parameters need to be disabled when disabling the MSI capability.

    Resolution

    To work around this problem, disable the MSI 64-bit Addressing parameter in the IP Parameter Editor by following the steps below:

    1. Enable the MSI Capability parameter to access the 64-bit Addressing parameter (Under PCIe Settings>MCDMA Settings)
    2. Uncheck the "Enable MSI 64-bit Addressing" parameter
    3. Uncheck the "Enable MSI Capability" parameter
    4. Regenerate the IP and recompile the design.

     

    This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 23.1
