Structs and dynamic arrays/queues

archive

Hi all, I'm trying to rewrite an e code to SV that includes a list of structs when those structs contain a list of structs themselves. The e code: As you can notice the code creates a 3-dimensions array which the size of one of its dimensions isn't predefined. The equivalent option for a list, which its size isn't predefined in SV, is a dynamic array or a queue. The problem is that none of them can be used as a data member in struct. I also tried to create a 3-D array with one of its dimension as a dynamic array but this failed also. Can anybody think of a way to implement it in SV?

    Hi again,
    I implemented the class basic_struct_list_s with a queue as a data member since I want to use some of the built in methods for queues. Is there a way to use these methods (in particular the find methods such as find_first(), find_first_index) when the queue is a queue of classes and other class data member? I tried to do it like this:

    < code > 
    ...
    class basic_struct;
          uint lo_addr;
          uint hi_addr;
          string addr_name;
    endclass

    class basic_struct_list_c;
          basic_struct basic_struct_list[$];
    endclass basic_struct temp_struct;

    basic_struct_list_c master[6]
    ...
    initial
    begin
          temp_struct = new;
          for (i=0 ; i<6 ; i++ )
                begin master[i] = new;
          end // for (i=0 ; i<6 ; i++ )
    ... 
          temp_struct = master[0].basic_struct_list.find_first((item.lo_addr<=4) && (item.hi_addr>=5)); ...
    end //initial
    < /code >

    I received the following error:


       temp_struct = master[0].basic_struct_list.find_first( (item.lo_addr<=4) && (item.hi_addr>=5) );
                                                                                      |
    ncvlog: *E,QAANBI (test_program1.v,91|55): This is not a valid built in method name for this object. [SystemVerilog].
       temp_struct = master[0].basic_struct_list.find_first( (item.lo_addr<=4) && (item.hi_addr>=5) );
                                                                                      |
    ncvlog: *E,NOTFXX (test_program1.v,91|55): expecting a function name [10.3.3(IEEE)].
