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 Error (175001): The Fitter cannot place 1 HSSI_PMA_CDR_PLL, which is within Transceiver Native PHY Intel Arria 10 FPGA IP edp_rx_phy_16b_a...

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.

    Hi Dlim,

    Thanks for your explain.

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

    Thanks
