Randomization of a variable before all other variables

In reply to 8Blades:

If a variable ‘a’ is ‘randc’, it will be solved before ‘rand’ variables.

Also, second approach:



class my_class;
  rand bit [7:0] a;
endclass

class seq_item extended from class umv_sequence_item;
   bit [7:0] a; // not random 
   my_class my_class_h;
   rand bit [7:0] b,c,d ,e ...... ,x,y,z; // 'a' is removed
   /* constraint prob{ solve a before b;
                    solve a before c;
                    solve a before d;
                    .....
                    .....
                    solve a before z;
                   }
    */

   function void pre_randomize();
      my_class_h = new(); my_class_h.randomize();
      a = my_class_h.a;
   endfunction: pre_randomize
 
    endclass
