Method detail

ControlFileStackup.add_material(material_name, permittivity=1.0, dielectric_loss_tg=0.0, permeability=1.0, conductivity=0.0, properties=None)

Add a new material with specific properties.

Parameters:

material_namestr

Material name.

permittivityfloat, optional

Material permittivity. The default is 1.0.

dielectric_loss_tgfloat, optional

Material tangent losses. The default is 0.0.

permeabilityfloat, optional

Material permeability. The default is 1.0.

conductivityfloat, optional

Material conductivity. The default is 0.0.

propertiesdict, optional

Specific material properties. The default is None. Dictionary with key and material property value.

Returns:

pyedb.dotnet.database.edb_data.control_file.ControlFileMaterial

ControlFileStackup.add_layer(layer_name, elevation=0.0, material='', gds_type=0, target_layer='', thickness=0.0, layer_type='conductor', solve_inside=True, properties=None)

Add a new layer.

Parameters:

layer_namestr

Layer name.

elevationfloat

Layer elevation.

materialstr

Material for the layer.

gds_typeint

GDS type assigned on the layer. The value must be the same as in the GDS file otherwise geometries won’t be imported.

target_layerstr

Layer name assigned in EDB or HFSS 3D layout after import.

thicknessfloat

Layer thickness

layer_typestr

Define the layer type, default value for a layer is "conductor"

solve_insidebool

When True solver will solve inside metal, and not id False. Default value is True.

propertiesdict

Dictionary with key and property value.

Returns:

pyedb.dotnet.database.edb_data.control_file.ControlFileLayer

ControlFileStackup.add_dielectric(layer_name, layer_index=None, material='', thickness=0.0, properties=None, base_layer=None, add_on_top=True)

Add a new dielectric.

Parameters:

layer_namestr

Layer name.

layer_indexint, optional

Dielectric layer index as they must be stacked. If not provided the layer index will be incremented.

materialstr

Material name.

thicknessfloat

Layer thickness.

propertiesdict

Dictionary with key and property value.

base_layerstr, optional

Layer name used for layer placement. Default value is None. This option is used for inserting dielectric layer between two existing ones. When no argument is provided the dielectric layer will be placed on top of the stacked ones.

methodbool, Optional.

Provides the method to use when the argument base_layer is provided. When True the layer is added on top on the base layer, when False it will be added below.

Returns:

pyedb.dotnet.database.edb_data.control_file.ControlFileDielectric

ControlFileStackup.add_via(layer_name, material='', gds_type=0, target_layer='', start_layer='', stop_layer='', solve_inside=True, via_group_method='proximity', via_group_tol=1e-06, via_group_persistent=True, snap_via_group_method='distance', snap_via_group_tol=1e-08, properties=None)

gds_typeint

Define the gds type.

target_layerstr

Target layer used after layout import in EDB and HFSS 3D layout.

start_layerstr

Define the start layer for the via

stop_layerstr
