Create a cheese cell based on input of no-cheese locations.
Create cheesing polygons based on the no-cheese regions.
- Parameters:
multi_poly – No-cheese areas per layer (shapely multipolygon).
all_nocheese_gds – Same geometry in a gdstk-friendly list.
lib – Library that will hold all generated cells.
minx – Chip minimum x location.
miny – Chip minimum y location.
maxx – Chip maximum x location.
maxy – Chip maximum y location.
chip_name – User-defined chip name.
edge_nocheese – Buffer around the chip perimeter to leave un-cheesed.
layer – Layer number for calculating the cheese.
is_neg_mask – If True, export a negative mask; otherwise positive.
datatype_cheese – Datatype for cheese polygons.
datatype_keepout – Datatype for keepout regions.
fab – If True, output fabrication-ready layers; if False, include intermediate/debug layers.
max_points – Maximum number of points for a polygon in gdstk.
precision – gdstk precision to use.
logger – Logger to emit warnings/errors.
cheese_shape – 0 for rectangle, 1 for circle.
shape_0_x – Rectangle width (centered at 0,0).
shape_0_y – Rectangle height (centered at 0,0).
shape_1_radius – Circle radius.
delta_x – Spacing between holes in x.
delta_y – Spacing between holes in y.
