Error (14566): The Fitter cannot place 4 periphery component(s) due to conflicts with existing const

Hi,

How can fix the errors?

I really can't understand

    Hi,


    Based on the fitter error report, likely there is an pin placement issue on either your CDR refclk pin or transceiver Rx channel pin


    I can help to review your design if you can share your archived design QAR file here.


    Thanks.


    Regards,

      Use tool : Quartus 18.1 prime standard

      Family: Arria 10

      Device: 10AX115S3F45E2SGE3

      below is design (rx_cdr_refclk0 = 100MHz)

      pin planner

      set_location_assignment PIN_AC8 -to rx_cdr_refclk0
      set_location_assignment PIN_AC7 -to "rx_cdr_refclk0(n)"
      set_instance_assignment -name IO_STANDARD LVDS -to edp_ref_clk_p

      set_location_assignment PIN_H5 -to rx_serial_data[0]
      set_location_assignment PIN_G7 -to rx_serial_data[1]
      set_location_assignment PIN_F5 -to rx_serial_data[2]
      set_location_assignment PIN_E7 -to rx_serial_data[3]

      set_location_assignment PIN_H6 -to "rx_serial_data[0](n)"
      set_location_assignment PIN_G8 -to "rx_serial_data[1](n)"
      set_location_assignment PIN_F6 -to "rx_serial_data[2](n)"
      set_location_assignment PIN_E8 -to "rx_serial_data[3](n)"

      set_instance_assignment -name IO_STANDARD "HIGH SPEED DIFFERENTIAL I/O" -to rx_serial_data[0]
      set_instance_assignment -name IO_STANDARD "HIGH SPEED DIFFERENTIAL I/O" -to rx_serial_data[1]
      set_instance_assignment -name IO_STANDARD "HIGH SPEED DIFFERENTIAL I/O" -to rx_serial_data[2]
      set_instance_assignment -name IO_STANDARD "HIGH SPEED DIFFERENTIAL I/O" -to rx_serial_data[3]

        Hi dlim,

        If I try to modify design as below, the error message disappear,

        but the source ref clk of the frequency of rx_clkout_16b and rx_clkout_20b are different make 16_to_20bit_fifo module error.

        Therefore, I want to use the original design.

        What's the problem of the original design?

    Hi,


    From the diagram that you drew, likely this is due to resource sharing issue.

    • You are using same CDR_refclk source to clock 2 NativePHY IP where by one transceiver bank only contains 6 channel.
    • If you are using CMU PLL, then it will eat up extra transceiver channel as well.
    • I am guessing once you remove the second NativePHY design then it free up some transceiver channel resource, that's why no more error


    I can't analyze the issue further unless you can share with me your design QAR file. I need to cross check your NativePHY IP setting vs your transceiver pin setting.


    Anyway, my suspect is due to insufficient transceiver channel resource sharing issue that caused the error


    Thanks.


    Regards,

    dlim

      Hi Dlim,

      Thanks for your explain.

      And what's the QAR file mean ? How can I get this file?

      Thanks

    HI,


    Once you completed Quartus Analysis and Synthesis compilation, then you can goto

    1. In the Quartus II software, from the Project menu, choose Archive Project.
    2. Quartus will compress your Quartus design into *.qar file that you can share to me


    You can refer to below link for more detail.


    Let me know you are using which Quartus version


    Thanks.


    Regards,

    dlim

    HI,


    Just to follow up.


    Do you still plan to share your design for me to review ?


    Thanks.

      Hi Dlim,

      Sorry for replying late.

      I have already change my design let project can keep going.

      I will modify the design back to the original version then share design to you one day.

      Thanks for your help.

    HI,


    I am setting this case to closure since I never hear back from you.
