<pre>ECO command. Fix the whole design in global mode
<b>Usage:</b> fix_design(@options);
@options:
    -help: Print this information
    -opt_set optimization_set: Patch optimization set, 0: area/timing 1: cell count, default 0
    -no_patch_opt: Disable patch optimization. Also see API set_no_patch_opt
    -flatten: Enable flatten mode ECO. The default mode is hierarchical
    -list_file the_list_file: The ECO point list file converted from RTL-to-RTL LEC result
             The list file format:
                inst u_def/u_sdef/state_reg_1_
                pin  u_control/u_sreg/u_mem_128x24/A[0]
                port PORT_READY_OUT
    -iteration iteration_number: Fix design iteration by default 3 times.
          The tool repeats the fix process until there is no non-equivalent points or iteration number reached
<b>Examples:</b>

#1. Fix design on module 'VIDEO_TOP' and its sub-modules
set_top('VIDEO_TOP');
set_ignore_output("TEST_SO*");
set_pin_constant("TEST_EN", 0);
fix_design;
save_session("this_eco");
my $error = LEC;

#2. Do ECO in flatten mode
fix_design("-flatten");

#3. Do ECO on points listed in the file
fix_design("-list_file", $list_file);
