How to suppress the warning -- ASSERT/WARNING (time 277932200 PS) from package ieee.NUMERIC_STD

usha sudhagar
We are using “irun” to run our testcase and we are getting the below warning.  Due to this, we are getting a very huge log file (interms of GB).  Please could you suggest why we are getting this warning and how to suppress the same?

Built-in relational argument contains a ('U', 'X', 'W', 'Z', '-') in an operand.

ASSERT/WARNING (time 277932200 PS) from package ieee.NUMERIC_STD, this builtin function called  from process system.u_chip.u_core.u_cpsTop:u_ethComplex:i_ethTopModule:i_ethManipulationModuleToSerDes:EnetBypassLogicGen(3):i_emmBypassToSerDes:i_loopbackfifo:u_genericTwoPortRam1R1W:projectRamGen:u_projectRamFile:regFileGen:notDualPortRegFileGen:u_genericRegisterFile:regFileB_proc (architecture eth_lib.genericRegisterFile:synth)

Built-in conversion function argument contains ('U', 'X', 'W', 'Z', '-') in an operand (treated as '0').

    At the ncsim prompt,

    ncsim> set severity_pack_assert_off {warning}
    ncsim> set pack_assert_off { std_logic_arith numeric_std }

    The following commands will turn off assert warning messages (the listed severity) from packages std_logic_arith and numeric_std (the two listed packages).

    Note that the first command is optional if the severity_pack_assert_off variable is already set to warning.

    Or if you want to give these TCL commands as input file and automate the flow. You can put these commands in a file like,

    input.in
    --------
    set severity_pack_assert_off {warning}
    set pack_assert_off { std_logic_arith numeric_std }
    ------------------------------

    %ncverilog -input input.in <other_commands>

    %irun -input input.in <other_commands>
