error C_MEM_CAS_LATENCY, Not able to find a suitable memory CAS latency

Hello, I having this error, and I do not understand where it comes from, anywhere I am working at 400MHz.

 

ERROR:EDK:3900 - issued from TCL procedure
   "::hw_mpmc_v6_02_a::syslevel_update_mem_cas_latency" line 76
   C_MEM_CAS_LATENCY (IPNAME:mpmc, INSTANCE:coef_mpmc) - Not able to find a
   suitable memory CAS latency for frequency 400.0MHz (2500ps.)  If this is your
   intended clock frequency, please ensure you have set the
   C_MEM_PART_CAS_[A-D], and C_MEM_PART_CAS_[A-D]_FMAX parameters correctly.
   Please see the MPMC data sheet for more details on these parameters.
ERROR:EDK:1585 - IPNAME:mpmc INSTANCE:coef_mpmc -
   I:\Xilinx\12.3\ISE_DS\EDK\hw\XilinxProcessorIPLib\pcores\mpmc_v6_02_a\data\mp
   mc_v2_1_0.mpd line 288 - error computing override value for C_MEM_CAS_LATENCY
   using tcl

 

Looking my MHS file I have this parameters for

 

 PARAMETER C_MEM_PART_CAS_A_FMAX = 200
 PARAMETER C_MEM_PART_CAS_A = 3

 

 

Here I will attach my MHS.

 

Thanks in advance

 

Regards,
