In reply to mlsxdx:
This has nothing to do with being an anonymous type. The implicit data type of any enum is a 2-state int. The default initial value of an enum is the default initial value of its data type, which is 0 because that default type is an int. .

I see. Is there any way to skip time 0 nxt_st changes trigger always, especially if 0 is defined a non-initial state.


   always @(nxt_st) begin
      $display("%0t: 'h%0h",$realtime, nxt_st);
      // The unname enum 0 will trigger the logic below, how can I filter out the sim time 0 here?
      if(nxt_st != 'h40) begin
        //statement
      end
   end
