This file contains user-defined verilog modules that are found in the openfpga_cell_library with ports declaration (compatible with other netlists that are auto-generated by OpenFPGA) but without functionality. The file is used as a reference for engineers to check what is the port sequence required by top-level verilog netlists. This file can be included in simulation only if there are modifications to the file.
To implement our own ADDF module, we need to remove all other module definitions (they are already defined elsewhere and will cause an error if left in). Replace the ``user_defined_templates.v`` file with the following:
``//-------------------------------------------

We can now link this ``user_defined_templates.v`` into ``k6_frac_N10_adder_chain_40nm_openfpga.xml``.
