Mixing of ansi & non-ansi style port declaration is not legal

Hi,
I am getting error in NCSIM.

Errors;

*ncvlog: E,ILLPDL (./…//altera_emif_mem_model_core_ddr4_161/sim/altera_emif_ddrx_model_per_device.sv,144|13): Mixing of ansi & non-ansi style port declaration is not legal. asssign rcdif.CK_L= mem_ck_n;
|
In this CK_L is Logic type and mem_ck_n is also logic type.

why simulator is giving this type of error??/

Is any one pls help me ???/

Thanks

In reply to Muthuvenkatesh:

Show us your port declaration. Also is this

asssign rcdif.CK_L= mem_ck_n;

actually in your code? You have a syntax error; too many s’s in assign.
