ERROR: [Opt 31-67] Problem: A LUT2 cell in the design is missing a connection on input pin I0, which is used by the LUT equation. This pin has either been left unconnected in the design or the connection was removed due to the trimming of unused logic. The LUT cell name is: partition_wrapper/partition/dwidth_adapt_64bits_512bits_1/inst/gen_upsizer.gen_full_upsizer.axi_upsizer_inst/USE_READ.gen_pktfifo_r_upsizer.pktfifo_read_data_inst/dw_fifogen_ar_i_21.
Resolution: Please review the preceding OPT INFO messages that detail what has been trimmed in the design to determine if the removal of unused logic is causing this error. If opt_design is being specified directly, it will need to be rerun with opt_design -verbose to generate detailed INFO messages about trimming.

FireSim Xilinx Alveo xilinx_vcu118 FPGA Build Failed
Your FPGA build failed for quintuplet: xilinx_vcu118-firesim-FireSim-FireSimRocket4GiBDRAMConfig-BaseXilinxVCU118Config
ERROR: A bitstream build failed.
Fatal error.

However, I'm having trouble resolving this error. I tried using the 'set dont touch' attribute, but it was not successful.
Can anyone provide guidance on how to resolve this issue?
Thank you !

This seems to be a standard error, and I found a related article on the Xilinx support website: https://support.xilinx.com/s/article/70111?language=en_US
