Function libreda_pnr::util::pin_detection::assign_pin_shapes_from_text_labels

pub fn assign_pin_shapes_from_text_labels<L: L2NEdit<Coord = Coord>>(
    layout: &mut L,
    cell: &L::CellId,
    pin_shape_layer: &L::LayerId,
    label_layer: &L::LayerId
)

Associate pins and shapes based on a layer containing all polygon shapes and a layer containing text labels. The text labels mark the shapes that belong to a pin. For each text label all this shapes are grouped together.

The naive algorithm used is very inefficient but good enough for standard-cells. Especially if it is used in a pre-computation step which is not time-critical.

Parameters

• layout: The layout and netlist data structure.
• cell: The cell of which pins should be found.
• pin_shape_layer_id: The layer which contains the pin shapes.
• label_layer_id: The layer which contains the text labels of the pins.
