Classes

AutoTransition

class AutoTransition(registry: Optional[Mapping[Union[Tuple[IWaveguideType, IWaveguideType],
                        Tuple[Type[IWaveguideType], Type[IWaveguideType]]], Union[Callable[[],
                        Tuple[ICurvedCellRef, Tuple[str, str]]], Callable[[Tuple[IWaveguideType, IWaveguideType]],
                        Tuple[ICurvedCellRef, Tuple[str, str]]]]]] = None, /)

Registry for auto transition, used in fp.Linked / fp.LinkBetween / fp.LinkSmooth.

Usage:

# (see gpdk.technology.auto_transition)

from fnpcell.pdk.technology import all as fpt
from gpdk.technology import WaveguideType
from gpdk.components.transition.swg2mwg_transition import SWG2MWGTransition

def _swg2mwg(types: Tuple[fpt.IWaveguideType, fpt.IWaveguideType]):
    return SWG2MWGTransition(name="auto", swg_length=10, mwg_length=10, swg_type=types[0], mwg_type=types[1])

auto_transition = fpt.AutoTransition()
auto_transition += WaveguideType.SWG.C >> WaveguideType.MWG.C, _swg2mwg
