Command Reference2.  FPGA Express Shell Commands  set_chip_effort



_N_A_M_E
          set_chip_effort
                         Specify the chip optimization effort.


SYNTAX
          string set_chip_effort [_h_i_g_h | _l_o_w]

          string _h_i_g_h, _l_o_w


ARGUMENTS
          _h_i_g_h, _l_o_w      Optimization effort levels.


DESCRIPTION
          This command defines the default optimization effort
          level for all modules of the current chip.  The effort
          level must be either _h_i_g_h or _l_o_w.  An effort level of
          _h_i_g_h will instruct the optimizer to use additional
          optimization steps which may improve the quality of
          results at the expense of additional run-time. An
          effort level of _l_o_w will disable some optimizations
          steps which may result shorter run-times at the expense
          of quality of results.

          To control the optimization effort for specific modules
          of the chip use the command set_module_effort.

          The current chip must be defined by using the command
          current_chip before executing this command, otherwise
          an error will be reported.


EXAMPLES
          Set the chip optimization effort to high on the chip
          "mychip1".

          fe_shell > current_chip mychip1
          fe_shell > set_chip_effort high


          Set the chip optimization effort to low on the chip
          "mychip2".

          fe_shell > current_chip mychip2
          fe_shell > set_chip_effort low
