Usage:   dragon [-f aux_file | -q config_file | design-name] [-options] 
  aux_file: bookshelf format auxilary file name;
  config_file: LEF/DEF format config file name;
  options:
    -tw			TimberWolf format input;
    -yal		YAL format input (with -row or .gdp file);
    -fd			Fixed-die placement (for bookshelf or LEF/DEF format only);
    -dp			Detailed Placement (greedy improvement) ;
    -row		number of rows (for TimberWolf/YAL format only);
    -fast		fast mode (worse quality);
    -rs row_spacing	0.0-1.0 (from 0 to standard cell height);
    -dis		creates a display file(.disp), use pdisp to display it;
    -pc			center-of-cell for .pl file in bookshelf;
    -con		congestion reduction as the post-processing step;
    -cbin m n		bin grids for congestion reduction;
    -cp v h		vertical/horizontal edge capacities for 
    			congestion reduction;
