gdsfactory.technology.LayerStack

class gdsfactory.technology.LayerStack(*, layers=<factory>)

For simulation and 3D rendering. Captures design intent of the chip layers after fabrication.

Parameters:

layers (dict[str, LayerLevel]) – dict of layer_levels.

__init__(**data)

Add LayerLevels automatically for subclassed LayerStacks.

Parameters:

data (Any)

Return type:

None
