Exporter_GDS

class zeroheliumkit.src.importing.Exporter_GDS(name: str, zhk_layers: dict, layer_cfg: dict)

Bases: object

A class for exporting geometries to GDSII format using gdstk.

Parameters:

• name (str) – The base name of the GDSII file (without extension).

• zhk_layers (dict) – A dictionary containing the geometries for each layer. Expected: zhk_layers[lname].geoms yields shapely polygons.

• layer_cfg (dict) – A dictionary containing the layer configuration. Expected keys like {“layer”: int, “datatype”: int}.

Methods

preapre_gds()	Prepare the GDSII library by creating a top-level cell and adding polygons.
save()	Saves the GDSII file.

preapre_gds() → None

Prepare the GDSII library by creating a top-level cell and adding polygons.

Notes vs gdspy: - gdstk does not have exclude_from_current; cells are not automatically “current”. - gdstk polygons use layer and datatype (same concepts).

save()

Saves the GDSII file.
