A function that returns the mapping of the ``matched_component`` in the corresponding netlist at any particular level of recursion. This function iterates over a particular level of recursion of a netlist. It returns a list of the missing required components, and updates a dictionary of measurement that contains a particular matching component. It returns the corresponding list of instances of a particular component at that level of recursion, so that it can be appended upon in order to construct the location of the corresponding matching elements. If ``required_models`` is an empty list, it means no recursion is required and the function is complete. If a ``required_model_i`` in ``required_models`` matches ``target_component_prefix``, then no more recursion is required down the component function. The ``recursive_netlist`` should contain all the missing composed measurement that are not provided in the main measurement dictionary. If not, then we need to require the user to input the missing model that cannot be extracted from the composed netlist. We know when a model is composed, and when it is already provided at every level of recursion based on the ``measurement`` dictionary that gets updated at each level of recursion with the corresponding measurement of that level, and the ``required_models`` down itself. However, a main question appears on how to do the recursion. There needs to be a flag that determines that the recursion is complete. However, this is only valid for every particular component in the ``required_models`` list. Every component might have missing component. This means that this recursion begins component by component, updating the ``required_models`` list until all of them have been composed from the recursion or it is determined that is it missing fully. It would be ideal to access the particular component that needs to be implemented. Returns a tuple of ``model_composition_mapping, instance_composition_mapping, target_component_mapping`` in the form of ({'mzi_214beef3': ['straight_heater_metal_s_ad3c1693']}, {'mzi_214beef3': ['mzi_1', 'mzi_5'], 'mzi_d46c281f': ['mzi_2', 'mzi_3', 'mzi_4']}) Args: recursive_netlist (dict): The hierarchical netlist dictionary. top_level_instance_name (str): The name of the top-level instance to start the search from. required_models (list): A list of measurement that need to be included in the recursion. target_component_prefix (str): The prefix of the component instances to locate. models (dict): A dictionary of measurement provided to aid in the recursion. Returns: tuple: A tuple containing: - model_composition_mapping (dict): A mapping of required measurement to their composed measurement. - instance_composition_mapping (dict): A mapping of required measurement to their corresponding instances. - target_component_mapping (dict): A mapping of target components to their parent components. .. py:function:: get_component_instances(recursive_netlist: dict, top_level_prefix: str, component_name_prefix: str) Returns a dictionary of all instances of a given component in a recursive netlist. Args: recursive_netlist (dict): The hierarchical netlist dictionary. top_level_prefix (str): The prefix of the top-level instance to search under. component_name_prefix (str): The prefix of the component instances to find. Returns: dict: A dictionary mapping the component prefix to a list of instance names that match the prefix. .. py:function:: get_netlist_instances_by_prefix(recursive_netlist: dict, instance_prefix: str) -> str Returns a list of all instances with a given prefix in a recursive netlist. :param recursive_netlist: The hierarchical netlist dictionary. :type recursive_netlist: dict :param instance_prefix: The prefix to search for within the netlist instances. :type instance_prefix: str :returns: The name of the instance that matches the given prefix. :rtype: str :raises ValueError: If no instance or more than one instance matches the given prefix. .. py:function:: get_matched_model_recursive_netlist_instances(recursive_netlist: dict, top_level_instance_prefix: str, target_component_prefix: str, models: Optional[dict] = None, custom_subcomponent_instance: Optional[str] = 'sxt') -> list[tuple] This function returns an active component list with a tuple mapping of the location of the active component within the recursive netlist and corresponding model. It will recursively look within a netlist to locate what measurement use a particular component model. At each stage of recursion, it will compose a list of the elements that implement this matching model in order to relate the model to the instance, and hence the netlist address of the component that needs to be updated in order to functionally implement the model. It takes in as a set of parameters the recursive_netlist generated by a ``gdsfactory`` netlist implementation. Returns a list of tuples, that correspond to the phases applied with the corresponding component paths at multiple levels of recursion. eg. [("component_lattice_gener_fb8c4da8", "mzi_1", "sxt"), ("component_lattice_gener_fb8c4da8", "mzi_5", "sxt")] and these are our keys to our sax circuit decomposition. :param recursive_netlist: The hierarchical netlist dictionary. :type recursive_netlist: dict :param top_level_instance_prefix: The prefix of the top-level instance to search under. :type top_level_instance_prefix: str :param target_component_prefix: The prefix of the target component to find. :type target_component_prefix: str :param models: A dictionary of measurement to aid in the recursion. Defaults to None. :type models: Optional[dict] :param custom_subcomponent_instance: The instance name for subcomponents, used for backwards compatibility. :type custom_subcomponent_instance: Optional[str] :returns: A list of tuples, each containing the hierarchical path to the matched component instances. Each tuple has the form (parent_component, target_instance, custom_subcomponent_instance). :rtype: list[tuple]
