Hi,
I'm trying to use autoinst for a module where the port list is partly defined in an include file that is auto-generated by a tool:

module lower_module (
    input in1,
    input in2,
    output out1,
    `include "list_of_auto_generated_ports.v"
    );
  some_logic
endmodule

Is there a way for AUTOINST to read the include file and use it at a higher level?
Here's what I'm expecting:

module  higher_module (
     /*AUTOINPUT*/
     input in1,
     input in2,
     /*AUTOOUTPUT*/
     output out1,
     output port1_from_include_file,
     output port2_from_include_file,
     etc
  );

  lower_module u_lower_module
  (
     /*AUTOINST*/
     .in1 (in1),
     .in2 (in2),
     .out1 (out1),
     .port1_from_include_file (port1_from_include_file),
     .port2_from_include_file (port2_from_include_file)
      etc
  )
 
endmodule

Currently, it seems like the ports in the include files are ignored.
I do have the following at the bottom of my file:

// Local Variables:
// eval:(verilog-read-includes)
// End:

Thanks!

Sorry, but at present the autos cannot recognize the contents of an include file, beyond what read-includes does, which is to determine what values are constants (defines or parameters).

Thanks for the quick reply Wilson.
Is this something to be considered for supporting or is this the first request you got for this feature?
To be honest, I'm not sure how often a user might come across this scenario - probably not too often.

It's maybe the 3rd time this has come up. It would be fairly hard to implement.
