                         Set pad slew rate.


SYNTAX
          string set_pad_slew_rate _S_l_e_w _r_a_t_e _c_o_n_t_r_o_l _v_a_l_u_e
                 _p_o_r_t _l_i_s_t

         string  _S_l_e_w _r_a_t_e _c_o_n_t_r_o_l _v_a_l_u_e
         list    _p_o_r_t _l_i_s_t


ARGUMENTS
          _S_l_e_w _r_a_t_e      Output pad slew rate control
                         "slew_rate_control_value" is to be
                         assigned as the pad slew rate to each of
                         the ports to each of the ports in the
                         "port_list".
                         Slew rate selected could either be fast
                         or slow for an output or
                         bidirectionalport. The options are
                         specific to the implementation's target
                         type.


          _p_o_r_t _l_i_s_t      List of ports "port_list" gives the list
                         of ports, wherin the
                         slew_rate_control_value is to be
                         assigned to each of the ports in the
                         port_list.



DESCRIPTION
          "set_pad_slew_rate" sets the pad slew rate for the
          current chip. The first argument
          "slew_rate_control_value" specifies the pad slew rate
          type. The second argument "port_list" is a list of
          ports to apply the property to. The output is an
          integer, a 0 on success and 1 on failure.
          Each port has with it a valid list of slew rates that
          could be assigned to it.  If the value to be assigned
          is not one among the valid ones, then an error is
          reported, in addition a list of the valid values
          permitted is also displayed.


EXAMPLES
          fe_shell > create_project -dir . fesproj
          fe_shell > add_file prep1.vhd
          fe_shell > analyze_file
