Within ' disable iff ( ! reset ) , is the reset synchronous OR asynchronous?

In reply to ben@SystemVerilog.us:

Ben is there a way to check the aysnchronous part via reports ( $display() ) .

For example ::


 //  Within  procedural  blocks

   always @( negedge rst_n  ,  posedge clk ) 
    begin
 
       if ( ! rst_n )  begin
   
        $display($time,,,"...") ; //  Can  report  N  check  that  reset  was  asynchronous 
         
         //  Drive  initial  values  to  signals
       end
      else
        begin
          //  Non - Reset Logic  here
          .............................
        end
    end


Similarly can we have a report specifically when the reset is asserted in the concurrent assertion ?
