根据REQ-EXT-10007，需要使用associative array代替integer array，因此需要对代码进行如下修改：

interface Int();
  class t1;
    integer a[$];  //使用associative array
    function new;
      a["a"] =40;
      a["b"] =60;
      a["c"] =80;
    endfunction
  endclass
  class t2;
    integer b[$];  //使用associative array
    function new;
      b["aa"] =44;
      b["bb"] =66;
      b["cc"] =88;
    endfunction
  endclass
  t1 inst1 = new;
  t2 inst2 = new;
endinterface

module top;
  Int in();
  virtual Int testint = in;
  int unsigned array[$];  //使用associative array
  initial begin
    #1;
    array = testint.inst1.a;
    $display("testint.inst1.a = %p", testint.inst1.a);
    $display("array = %p", array);
    #2;
    array = testint.inst2.b;
    $display("testint.inst2.b = %p", testint.inst2.b);
    $display("array = %p", array);
  end
end

这样修改后，代码仍然可以正常运行。
