Hierarchical reference not allowed from within a package.

archive

Hi All,
We are trying this kind of example. We are having two files of these. It's giving  "Hierarchical reference  not allowed from within a package." at    class1_instance.class1_function(.....)     class2_instance.class2_function(......)

I tried passing both classes as members of a structure. but it giving same error when accessing member class functions from structure.

What's the solution to access functions of these classes in Program main Blocks.

file1.sv
_______________________

program main;

class1 class1_instance;
class 2 class2_instance;
initial begin
    class1_instance=new;
    class2_instance=new;
    call_task_from_other_file(class1_instance, class2_instance);
end
endprogram


file2.sv
________________________
task call_task_from_other_file(class1 class1_instance, class2 class2_instance);
    class1_instance.class1_function(.....)
    class2_instance.class2_function(......)
endtask

  • Thanks Ajeetha, for your reply. code contains  no package declaration or keyword. Just group of files with `include statements and all in include_path.
    Even it's giving same     Hierarchical reference  not allowed from within a package." for this type of code also, or when calling  sub_module tasks from class functions.

    interface intf1(input logic clk);
    endinterface

    program main (intf1 intf1_instance);
        forked_task;
    endprogram

    task forked_task
        dut_instance.dut_task;
    endtask

    module dut (intf1 intf1_instance);

        task dut_task;
        endtask

    endmodule


    module top;
        reg clk;
        intf1 intf1_instance (clk);
        dut dut_instance (intf1_instance);
        main main_instance (intf1_instance);
    endmodule
