Usage: gof [options] netlists

netlists:         Netlist files to be loaded. There can be multiple netlist files listed, 
                  if the design has more than one netlist files.
options:
  -h:               print out this info.
  -lib technology_library: Or '-synlib technoloty_library', Load in technology library (synthesis library) 
                    which has parameters for leaf gates. 
                    There can be multiple -lib options,
                    if the design has more than one technology library files.
  -v simulation_library:  Specify simulation library file name which has verilog definition 
                    for leaf gates, like AND2X4.
                    There can be multiple -v options, if the design has more than one simulation library.
                    Both -v and -lib options are for leaf gates definition.
                    But -lib can support more features, like logic cone extraction.
                    In some cases, some leaf cells don't have technology library, 
                    simulation lbrary is used instead to resolve the cells. 
                    -v option can coexist with -lib option.
  -vmacro macro_library_file: For ECO purpose. Each module in the file appears as leaf cell, and it can be added like other leaf cell in ECO.
                    When write out ECO netlist, the file content appear in the beginning of ECO netlist. And the ECO cell is added as a hierarchical 
                    sub-block.
  -y library_directory: Specify library directory, one file corresponds to one leaf gate.
                    +libext+.v should be used with -y option.
  +libext+.v:       Specify library file extension in library directory.
                    it can be +libext+.v+.vg+.vlib, 
                    if .vg and .vlib are also lib extensions.
  -run script_file.pl:  Invoke GofCall to run netlist processing script, GOF will stay in shell mode when the script finishs.
  -vn library_name: Specify none leaf gates library file. For example, a file has 
                    collection of macro cell which is defined by leaf gates. 
  -yn library_directory: The files in the directory are not defining leaf gates. 
  -shell:           Run in text mode with shell prompt, GofCall APIs can be run in interactive mode in shell
  -o log_file:      Save log file, default gatesof.log
  -Top_1 netlist_files: Load another netlist files to build Top_1 tree. The hierarchy will shown up in left side of GofViewer window.
                       You can use -Top_2 -Top_3 ... to load more netlist files.
                       Note, when this option takes all netlist files followed, so the main netlist files should appear before this option
                       For example, 'gof -lib tsmc.lib imp_netlist1 imp_netlist2 -Top_1 ref_netlist1 ref_netlist2' will create 
                       two trees in the left side of GofViewer window.
                       While, 'gof -lib tsmc.lib -Top_1 imp_netlist1 imp_netlist2 ref_netlist1 ref_netlist2' will build only 
                       one tree, since Top_1 option eats up all of the netlist files, the main tree is gone.
  +define+PARAMETER0+PARAMETER1:    Define PARAMETER0 PARAMETER1.
  -id mydesign:  Specify design id will appear on tile. Optional.
  -def def_file:    Load DEF, design exchange format, file.
  -defverbose:      Report all def error, otherwise only first 10 are reported. 
  -lef lef_file:    Load Library Exchange Format file.
                    There can be multiple -def options, 
                    if the design has more than one def files.
  -pdef pdef_file:  This option will be phased out. Use -def instead
                    Load in pdef file.  
                    There can be multiple -pdef options, 
                    if the design has more than one pdef files.
  -gtech gtech_file: Load in gtech file for wire matching.
  -sparelist spare_cells_list_file: Load in spare cells list file.
  -f file_list_file: Load all the files and options in the file_list_file
  -vcd vcd_file:    Load in VCD file for schematic annotation
  -textbutton:      Text mode button instead of image mode button in ECO operations
  -version:         Print out current version
  -licquery:        Query license usage

  gof -v /home/lib/tsmc_cells.v -v /home/lib/macro_cells.v +libext+.v -y /home/lib /home/netlist/top.v /home/netlist/soc.v
      ---  Multiple simulation library files, and some leaf cells are defined in '/home/lib' directory, 
           which uses '-y' option to resolve them

  gof -v /home/lib/tsmc_cells.v /home/netlist/soc0.v /home/netlist/soc1.v -id the_soc_design
      ---  You would like to display 'the_soc_design' as the title

      ---  Load in gtech file for RTL wire to netlist mapping
