+
+Module Rename Assistant
+-----------------------
+
+Module Rename Assistant is a tool to help users to craft module name files (see details in :ref:`file_formats_module_naming_files`).
+This tool is useful to adapt module naming from a fabric to another, considering the two fabrics share the same building blocks, i.e., tile, routing blocks *etc.*
+For example, when engineers craft a module naming file for a fabric ``A``, and would like to migrate the module naming rules for anthor fabric ``B``, module naming rules have to be adapted due to the changes on default names of building blocks.
+
+The tool can be found at ``/build/libs/libnamemanager/module_rename_assistant``
+
+The tool includes the following options:
+
+.. option:: --reference_fabricA_names <string>
+
+  Specifiy a reference module name file for fabric A. This is typically generated by OpenFPGA through the commmand :ref:`openfpga_setup_commands_write_module_naming_rules`. The reference fabric key file is treated as the baseline, on which the renamed module file will be compared to.
+
+.. option:: --renamed_fabricA_names <string>
+
+  Specify the hand-crafted module name file for fabric A, which is typically hand-crafted by users.
+
+.. option:: --reference_fabricB_names <string>
+
+  Specifiy a reference module name file for fabric B. This is typically generated by OpenFPGA through the commmand :ref:`openfpga_setup_commands_write_module_naming_rules`. The reference fabric key file is treated as the baseline, on which the renamed module file will be compared to.
+
+.. option:: --output <string>
+
+  Specify the renamed module name file for fabric B to be outputted. For example, the fabric A contains reference names:
+
+.. code-block:: xml
+
+  <module_name default="tile_1__1_" given="tile_4_"/>
+
+while the renamed module for fabric A includes:
+
+.. code-block:: xml
+
+  <module_name default="tile_1__1_" given="tile_big"/>
+
+the fabric B shares the same given name ``tile_4_`` but in a different default name.
+
+.. code-block:: xml
+
+  <module_name default="tile_2__2_" given="tile_4_"/>
+
+the resulting output renamed module file includes:
+
+.. code-block:: xml
+
+  <module_name default="tile_2__2_" given="tile_big"/>
