HI,


Simple debug approach that you can try out as below.

  • Update your IP core version to match with expected Quartus version. The error message seems to be complaining about you are not using updated IP core version
  • Remove/disable all transceiver refclk and data channel pin location assignment and let Quartus auto fit it by compiling your design again
  • Reduce some transceiver channel to see if the fitter error is caused by insufficient resource issue


Ultimately, you can also share your design QAR file here then I can help to review your design.


Thanks.
