zynq7000 MIG simulation error.Memory overflow.You must increase the MEM_BITS parameter or define MAX_MEM.

Jump to solution

I want to write the whole ddr3(64M16bit) in simulation but there is something wrong.

ERROR: Memory overflow. Write to Address 001000 with Data xxxxxxxxxxxxxxxx0000000000010000 will be lost.You must increase the MEM_BITS parameter or define MAX_MEM.

I try to define MAX_MEM in ddr3_model.sv,and modelsim displayed failed to open file.The MEM_BITS parameter in ddr3_model_parameters.vh is 15.AR# 47880 can not solve my problem.

Hi @poorcool 

open *.vh which is a file that defines all parameters that DDR2/DDDR3 simulation model uses.Modify MEM_BITS to a proper value. if didn't work then just simulate with other simulator and check the behavior.
