_N_A_M_E
          set_output_delay
                         Set the output delay for a port


SYNTAX
          string set_output_delay [-group _g_r_o_u_p__n_a_m_e] _d_e_l_a_y__v_a_l_u_e
                 _p_o_r_t__l_i_s_t

         string    _s_t_r_i_n_g
         int  _d_e_l_a_y__v_a_l_u_e
         list _p_o_r_t__l_i_s_t


ARGUMENTS
          -group _g_r_o_u_p__n_a_m_e
                         Name of the relative timing group.


          _d_e_l_a_y__v_a_l_u_e    Value for the output delay in
                         nanoseconds.


          _p_o_r_t__l_i_s_t      List of ports.  See object(2) for
                         describing port lists.


DESCRIPTION
          This command sets the output delay for an output or
          inout port.  This delay is the maximum delay from the
          port to the specified relative timing group. Without
          setting the output delay, the maximum delay is defined
          by the path group formed by the output port group and
          the relative timing group. The path group delay is
          subtracted from the output delay and added to to the
          required time of the port.


EXAMPLES
          Sets the output delay relative to the timing group
          "(RC,CLOCK)" to 10 for the port CARRY_OUT.  The path
          group used to determine the arrival time offset is
          "(RC,CLOCK):(O)".
