Glossary

Connectable

The generic type for most objects in Layout.

Objects of the following types are all connectables :

• Primitives
• Hierarchy
• Terminals

Zone

Multizone stackups allow a design to be divided into areas called zones.

Each zone contains a subset of layers available to the entire circuit board and is spatially defined by polygons on the Outline layer.

All zones (except the “fixed” zone) can have bends applied to them by defining BoardBendDefs on zone primitives.

ValueLike

Any of the following data types that represents a numeric value

• int

• float

• complex

• str for expressions (‘1nm’, ‘x + 1’ etc)

• Value

Point2DLike

Any of the following data types that represents (x, y) point on a 2D coordinate system.

• PointData

• (ValueLike, ValueLike) or any other iterable with 2 ValueLike inside

Point3DLike

Any of the following data types that represents (x, y, z) point on a 3D coordinate system.

• Point3DData

• (ValueLike, ValueLike, ValueLike) or any other iterable with 3 ValueLike inside

Triangle3DLike

(Point3DLike, Point3DLike, Point3DLike)

LayerLike

Any of the following data types that represent a layer.

• str

• Layer

NetLike

Any of the following data types that represent a net.

• str

• Layer

RoughnessModel

A Groisse roughness model is represented by a single value containing the roughness value. A Huray roughness model is represented by a tuple of the form [nodule_radius_value, surface_ratio_value]

Union[ValueLike, (ValueLike, ValueLike)]

HFSSSolverProperties

HFSS solver properties are represented by a tuple of the form [dc_thickness_type, dc_thickness_value, solve_inside_enabled]

(DCThicknessType, ValueLike, bool)

HFSSExtents

Extent box around the design, represented by a dict with the following key:values

dielectric: (float, bool)

Dielectric extent size. First parameter is the value and second parameter indicates if the value is a multiple.

airbox_horizontal: (float, bool)

Airbox horizontal extent size. First parameter is the value and second parameter indicates if the value is a multiple.

airbox_vertical_positive: (float, bool)

Airbox positive vertical extent size. First parameter is the value and second parameter indicates if the value is a multiple.

airbox_vertical_negative: (float, bool)

Airbox negative vertical extent size. First parameter is the value and second parameter indicates if the value is a multiple.

airbox_truncate_at_ground: bool

Whether airbox will be truncated at the ground layers.
