Vivado fails to close timing for U55C

[prateek-0328]

I am trying to build the open-nic-shell using Vivado 2022.1 with the following build parameters:

build_options

    -board_repo  ""
    -board       au55c
    -tag         ""
    -overwrite   0
    -rebuild     0
    -jobs        48
    -synth_ip    1
    -impl        1
    -post_impl   1
    -user_plugin ""
    -bitstream_userid  "0xDEADC0DE"
    -bitstream_usr_access "0x66669999"
    -sim  0`

design_params

    -min_pkt_len      64
    -max_pkt_len      1518
    -use_phys_func    1
    -num_phys_func    1
    -num_qdma         1
    -num_queue        512
    -num_cmac_port    2`

I am facing a negative slack in the generated bitstream:

Any solutions to resolve this issue?

I had the same issue for U55C with 2 CMAC ports.

As for issue #14, my solution was to use the "Performance Explore" implementation strategy.
