Creating ptf file and coe generator

I resolved it by swap e_avalon_master->adds and e_port->adds.

  $module->add_contents   (   
  
      e_port->adds(@x_ports),
      e_avalon_master->add
         ({
            name     => "x_master",
            type_map =>
            {
               clock        => "clk",
               reset_n        => "reset_n",            
               x_address => "address",
               x_write => "write",
               x_writedata => "writedata",
               x_read => "read",
               x_readdata => "readdata",
               x_waitrequest => "waitrequest",
             },
         }),
   );
