   - ``add_const_input="true|false"`` Specify if an extra input should be added to the multiplexer circuits. For example, an 4-input multiplexer will be turned to a 5-input multiplexer. The extra input will be wired to a constant value, which can be specified through the XML syntax ``const_input_val``.
