SYNTAX
          string update_chip [-recur] [-force] [-progress]
                             [_L_i_s_t _o_f _c_h_i_p_s]

          string    _L_i_s_t _o_f _c_h_i_p_s


ARGUMENTS
          -recur         Recursive update. Recursively updates
                         the dependencies of the chip before
                         updating the chip itself.

          -force         Force update.  Updates the chip even if
                         the chip is up to date.

          -progress      Show progress.  Displays the progress
                         messages while updating the chip.

          _L_i_s_t _o_f _c_h_i_p_s  Chips to be updated (e.g. tutor).



DESCRIPTION
          Updates chip. A pre-optimized chip will be re-
          elaborated if any of the designs used in the chip are
          out of date with respect to their source. An optimized
          chip will be re-optimized and/or re-elaborated if
          changes have been made to the source files,
          constraints, or optimization options. If "-force"
          option is set, the chip will be updated even if it is
          still up to date. If "-recur" option is set, it will
          first update the chip's underlying design files before
          updating the chip itself.


INCREMENTAL UPDATE
          By default, updating an optimized chip re-optimizes all
          modules in the chip when the chip's corresponding pre-
          optimized chip is newer than the optimized chip. When
          two or more blocks are defined on a chip, the
          incremental mode is enabled.  Blocks are defined using
          the command set_module_block(2).  In this incremental
          mode, instead of re-optimizing all the modules when the
          pre-optimized chip is newer than the optimized chip,
          only the modules contained in a block which are out-
          of-date with respect to their block in the pre-
          optimized chip are re-optimized.

update_chip     2.  FPGA Express Shell Commands Command Reference



          When the incremental mode is enabled, update will
          produce messages which indicate which optimized designs
          are out-of-date. For example:

               The optimized version of module 'test' is older
               than its implemented/elaborated version -
               discarding the optimized module.



EXAMPLES
          fe_shell > optimize_chip tutor
          fe_shell > update_chip -force -recur tutor
