dummy_fill_layout

ipkiss3.all.dummy_fill_layout(layout, filling=None, target_layer=<ipkiss3.technology.TechValue object>)

Applies a dummy fill to a layout based on filler spefications.

Provide multiple Filler objects in filling for multiple fill passes on different layer sets.

Parameters:

layout: Layout | LayoutView | PCell

A Layout, LayoutView or PCell to apply dummy filling to.

filling: Sequence[Filler] | None, optional, default=None

A sequence of Filler objects. If not specified, it is created from TECH.DUMMY_FILLING.FILLERS or an error is raised if the PDK does not specify it. TECH.DUMMY_FILLING.FILLERS must be a list of dicts, each dict specifying a set of Filler attributes.

target_layer: Layer | tuple[int, int] | None, optional, default=TECH.DUMMY_FILLING.TARGET_LAYER

A layer which defines the bounding area of the filling operation. If not specified, a default value from the PDK is used (TECH.DUMMY_FILLING.TARGET_LAYER) or None (entire layout) is used if the PDK does not specify it.

Returns:

dummy_filled_layout: Layout

A Layout data container which contains only the dummy instances, which are ARefs. You are supposed to add this to the layout in a generate method of a PCell
