Why no hold multicycle constraint is set to [get_keepers {*|PCIeCore_core:wrapper|altpcie_hip_pipen1b:altpcie_hip_pipen1b_inst|tl_cfg_ctl_wr}]?

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You may see the following warning in the Partial Multicycle section of Check Timing report when you compile a design targeting Stratix® IV GX or HardCopy® IV GX that uses Hard IP for PCI Express® in Quartus® II software version 11.1 or before.

    ; -from [get_keepers {*|PCIeCore_core:wrapper|altpcie_hip_pipen1b:altpcie_hip_pipen1b_inst|tl_cfg_ctl_wr}]  ; Setup multicycle for this path exists but no hold multicycle was set. ;

    This warning can safely be ignored since the default hold multicycle is expected on the path.

    The warning is scheduled to be suppressed in a future version of Quartus II software.
