Need help: *E,ILLPDL Error while compiling RTL design file which has typedef definition

Hi,

   I've a  below typedef definition;

         typedef enum {SP_FS='h00, LP_ID_END='h37, LP_RESERVED='h3F} DT_DATA_TYPE;

   The above typedef has been used in our RTL design files as below;

          DT_DATA_TYPE curr_pd;

          assign curr_pd = DT_DATA_TYPE'(data_type);    // input [5:0] data_type; input to the module

   After compiling the design file; I've got the below error;

      DT_DATA_TYPE curr_pd;
                                             |
     ncvlog: *E,ILLPDL (../../../../axi_mipi_receiver_dphy_new/rtl/append_extra_bytes.sv,69|21): Mixing of ansi & non-ansi style port declaration is not legal.

I don't understand the above issue and is working fine in other EDA tools. Please help in this regard?...

I'm using Incisiv 15.20.026 version.

Thanks,

Mahesh.
