pack_doe#

ubcpdk.cells.pack_doe(doe, settings, do_permutations=False, function=None, **kwargs)[source]#

Packs a component DOE (Design of Experiment) using pack.

Parameters:

  • doe (str | Callable[[...], Component] | dict[str, Any] | DKCell) – function to return Components.

  • settings (dict[str, tuple[Any, ...]]) – component settings.

  • do_permutations (bool) – for each setting.

  • function (str | Callable[[...], Component] | dict[str, Any] | None) – to apply (add padding, grating couplers).

  • kwargs – for pack.

Keyword Arguments:

  • spacing – Minimum distance between adjacent shapes.

  • aspect_ratio – (width, height) ratio of the rectangular bin.

  • max_size – Limits the size into which the shapes will be packed.

  • sort_by_area – Pre-sorts the shapes by area.

  • density – Values closer to 1 pack tighter but require more computation.

  • precision – Desired precision for rounding vertex coordinates.

  • text – Optional function to add text labels.

  • text_prefix – for labels. For example. ‘A’ for ‘A1’, ‘A2’…

  • text_offsets – relative to component size info anchor. Defaults to center.

  • text_anchors – relative to component (ce cw nc ne nw sc se sw center cc).

  • name_prefix – for each packed component (avoids the Unnamed cells warning). Note that the suffix contains a uuid so the name will not be deterministic.

  • rotation – for each component in degrees.

  • h_mirror – horizontal mirror in y axis (x, 1) (1, 0). This is the most common.

  • v_mirror – vertical mirror using x axis (1, y) (0, y).

  • function (str | Callable[[...], Component] | dict[str, Any] | None) – to apply to component (add padding, grating couplers).

  • with_text (bool) – includes text label.

  • kwargs – for grid.

Keyword Arguments:

  • spacing – between adjacent elements on the grid, can be a tuple for different distances in height and width.

  • separation – If True, guarantees elements are separated with fixed spacing if False, elements are spaced evenly along a grid.
