Enable compression on routing architecture modules. Strongly recommend this as it will minimize the number of routing modules to be outputted. It can reduce the netlist size significantly.
.. option:: --group_tile <string>
Group fine-grained programmable blocks, connection blocks and switch blocks into tiles. Once enabled, tiles will be added to the top-level module. Otherwise, the top-level module consists of programmable blocks, connection blocks and switch blocks. The tile style can be customized through a file. See details in :ref:`file_formats_tile_config_file`.
.. warning:: This option does not support ``--duplicate_grid_pin``!
.. warning:: This option requires ``--compress_routing`` to be enabled!
.. option:: --duplicate_grid_pin
Enable pin duplication on grid modules. This is optional unless ultra-dense layout generation is needed
