There's an example on the [[Faq]]. Beyond that I'm not sure what you are trying to do so would need an example.

Adding Example

Issue 1

interface calc_if (
input clk, input rst
);

logic add_sub;
logic [3:0] num1;
logic [3:0] num2;
logic [4:0] num3;

modport master (
output add_sub,
output num1,
output num2,
input num3
);

modport slave (
input add_sub,
input num1,
input num2,
output num3
);

endinterface

// Above code is part of an include file (calc_if.sv)

`include "calc_if.sv"
module top (/*AUTOARG*/);

calc_if.slave dut_calc_if;

dut DUT_INST (/*AUTOINST*/
               // Interfaces
               .dut_calc_if (dut_calc_if)
               // Inputs
               .dut_clk (dut_clk),
               .dut_rst (dut_rst)
              );

module dut (/*AUTOARG*/
             dut_clk,
             dut_rst
             );

Question : For both modules (top and dut) will the AUTOARG automatically populate the interface in the port list?
Am I missing something or this is incorrect?

If you have a solution can you point to me the FAQ?

Issue 2

// Interface declaration
calc_if dut1_to_dut2_calc_if();

dut1 DUT (/*AUTOINST*/
           // Interfaces
           .dut1_to_dut2_calc_if (dut1_to_dut2_calc_if),
          --- Other ports ---
           );

dut2 DUT (/*AUTOINST*/
           // Interfaces
           .calc_if (dut1_to_dut2_calc_if),
          --- Other ports ---
           );

Does the above interface declaration need to be added explicitly?
Is there any AUTO function that allows to do this?

Thanks

No because it doesn't know if the interface is for connection or for a port. Use ANSI style ports instead with input/output/interfaces in the module (...) instead of using AUTOARG.

Using ANSI as above should make this work.
