What does it mean??? --- WARNING:ConstraintSystem:134

I have a lot of such warnings, and it adds a lot to the compilation time: 

 

 

WARNING:ConstraintSystem:134 - Constraint <INST: UniqueName:
   /ACT_v1/EXPANDED/ACT_v1/DDR_SDRAM_MT46V16M16_5B/DDR_SDRAM_MT46V16M16_5B\/VFBC
   3_INST.vfbc\/VFBC1_PIM_NGC\/UVFBC\/GEN_BURST_CUT.GEN_MULTI_PORT.UCmdBuf\/cmd_
   mem_mux0000<103>1 TNM = D...>: No appropriate instances for the TNM
   constraint were found under block
   "DDR_SDRAM_MT46V16M16_5B/DDR_SDRAM_MT46V16M16_5B/VFBC3_INST.vfbc/VFBC1_PIM_NG
   C/UVFBC/GEN_BURST_CUT.GEN_MULTI_PORT.UCmdBuf/cmd_mem_mux0000<103>1"

   (type=LUT4).

 

 

How to get rid of it?

 

Thanks

Re: What does it mean??? --- WARNING:ConstraintSystem:134

Check Inst is not of type DCM/PLL which is not supported in UCF .
