gdsfactory.routing.add_pads_top(component: ComponentSpec = functools.partial(<function straight_heater_metal_undercut>, with_undercut=False, length_straight_input=0.1, length_undercut=5, length_undercut_spacing=0), **kwargs) Component[source]#

Returns new component with ports connected top pads.

Parameters:

component – component spec to connect to.

Keyword Arguments:
  • select_ports – function to select_ports.

  • port_names – optional port names. Overrides select_ports.

  • component_name – optional for the label.

  • cross_section – cross_section function.

  • get_input_labels_function – function to get input labels. None skips labels.

  • layer_label – optional layer for grating coupler label.

  • pad_port_name – pad input port name.

  • pad_port_labels – pad list of labels.

  • pad – spec for route terminations.

  • bend – bend spec.

  • straight_separation – from edge to edge.

  • straight – straight spec.

  • taper – taper spec.

  • get_input_label_text_loopback_function – function to get input label test.

  • get_input_label_text_function – for labels.

  • fanout_length – if None, automatic calculation of fanout length.

  • max_y0_optical – in um.

  • with_loopback – True, adds loopback structures.

  • list_port_labels – None, adds TM labels to port indices in this list.

  • connected_port_list_ids – names of ports only for type 0 optical routing.

  • nb_optical_ports_lines – number of grating coupler lines.

  • force_manhattan – False

  • excluded_ports – list of port names to exclude when adding gratings.

  • grating_indices – list of grating coupler indices.

  • routing_straight – function to route.

  • routing_method – get_route.

  • optical_routing_type – None: auto, 0: no extension, 1: standard, 2: check.

  • gc_rotation – fiber coupler rotation in degrees. Defaults to -90.

  • input_port_indexes – to connect.
