IP SDC: Could not find active CLKOUT ports for user facing clocks can't read "top_fab_inst_name": no such variable while executing "get_registers -nowarn ${top_fab_inst_name}hdpldadapt_tx_chnl_*~aib_fabric_pma_aib_tx_clk.reg"

Environment

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

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.2, you may see this error during compilation of the implementation revision, when partial reconfiguration is enabled and the F-Tile Avalon® Streaming Intel® FPGA IP for PCI Express* is being used:

    IP SDC: Could not find active CLKOUT ports for user facing clocks 

    can't read "top_fab_inst_name": no such variable

        while executing

    "get_registers -nowarn ${top_fab_inst_name}hdpldadapt_tx_chnl_*~aib_fabric_pma_aib_tx_clk.reg"

        invoked from within

    "set hdpldadapt_tx_pld_rst_n    [get_registers -nowarn ${top_fab_inst_name}hdpldadapt_tx_chnl_*~aib_fabric_pma_aib_tx_clk.reg]"

     (file "../../../../modules/c7_chip/main/src/tech/agilexf/map800_2vr0/ip_pcie_st_gen3x4/pcie_avst_f_600/synth/pcie_f_ip.sdc" line 440)

    ERROR: An error occurred during automatic periphery placement

     

    Resolution

    To work around this problem, remove the FAST_PRESERVE assignment, as F-Tile cannot be used with fast preservation. 

    This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
