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

  • Hello Mayank,

    I created a mini-testcase with the hope of understanding the issue you are running into. I was able to run my mini-test with the IUS5.83s3 release and an early adopter version of IUS6.1. Here is my code. Please try it out and let me know if it runs on your installation. Also - if I have misinterpreted your question, please let me know!

    Thanks!

    package my_pkg;
    class class1;
    integer v1 = 100;
    function void class1_function ();
    $display("class1_function: v1 is %0d", v1);
    endfunction
    endclass : class1

    class class2;
    integer v2 = 200;
    function void class2_function ();
    $display("class2_function: v2 is %0d", v2);
    endfunction
    endclass : class2

    task call_task_from_other_file (input class1 c1_inst, input class2 c2_inst);
    c1_inst.class1_function();
    c2_inst.class2_function();
    endtask
    endpackage : my_pkg;

    program main;
    import my_pkg::*;
    class1 class1_inst;
    class2 class2_inst;
    initial begin
    class1_inst = new();
    class2_inst = new();
    call_task_from_other_file(class1_inst, class2_inst);
    end
    endprogram
