passing 2-dimension array in DPI-SC

ravi999

Hi

I am able to pass one bit vector as an argument for DPI-SC.

test.v:
module test;
import "DPI-SC" function int c_func(input bit [7:0] data);

bit [7:0] data;
int j;

initial begin
 data=8'h1;
 j=c_func(data);

end

endmodule

code.cpp
#include <iostream>
using namespace std;

#define NCSC_INCLUDE_TASK_CALLS
#include "systemc.h"
#include "svdpi.h"

int c_func(svBitVecVal h) {
 cout<<h;
 return 0;
}

NCSC_REGISTER_DPI(c_func)

Above code is working. 

But I am unable to pass 2-dimension array as an arguement.

Is there any way to pass 2-D bit array as an argumenet for DPI-SC?

 

  •  may be you will get some help from this example

     program main;

               import "DPI-C" function void get_nums(output logic [15:0] nums[10]);

               logic [15:0] nums[10];

               initial begin
                   get_nums(nums);
                   foreach (nums[i]) $display(i,nums[i]);
               end
          endprogram

     

    #include "svdpi.h"

          void fib(svLogicVecVal nums[10]) {
              int i;
              for (i=0; i<10; i++) {
                  nums[i] = i ;
              }
          }

     

    Regards,
