Property detail#

property Layout.cell#

Cell: Owning cell for this layout.

Read-Only.

property Layout.layer_collection#: LayerCollection : Layer collection of this layout.

property Layout.fixed_zone_primitive#: Primitive : Fixed zones primitive.

property Layout.terminals#

Get terminals belonging to active layout.

Returns:

Terminal dictionaryDict[str, pyedb.dotnet.database.edb_data.terminals.Terminal]

property Layout.cell_instances#

list of CellInstance : List of the cell instances in this layout.

Read-Only.

property Layout.layout_instance#

LayoutInstance : Layout instance of this layout.

Read-Only.

property Layout.nets#

Nets.

Returns:

property Layout.groups#

property Layout.pin_groups: list[pyedb.dotnet.database.edb_data.sources.PinGroup]#

property Layout.net_classes: list[pyedb.dotnet.database.edb_data.nets_data.EDBNetClassData]#

property Layout.extended_nets: list[pyedb.dotnet.database.edb_data.nets_data.EDBExtendedNetData]#

property Layout.differential_pairs: list[pyedb.dotnet.database.edb_data.nets_data.EDBDifferentialPairData]#

property Layout.padstack_instances: list[pyedb.dotnet.database.edb_data.padstacks_data.EDBPadstackInstance]#: Get all padstack instances in a list.

property Layout.voltage_regulators: list[pyedb.dotnet.database.cell.voltage_regulator.VoltageRegulator]#

property Layout.port_reference_terminals_connected: bool#

bool: Determine if port reference terminals are connected, applies to lumped ports and circuit ports.

True if they are connected, False otherwise. Read-Only.

Method detail#

Layout.expanded_extent(nets, extent, expansion_factor, expansion_unitless, use_round_corner, num_increments)#

Get an expanded polygon for the Nets collection.

Parameters:

netslist[Net]: A list of nets.
extentExtentType: Geometry extent type for expansion.
expansion_factorfloat: Expansion factor for the polygon union. No expansion occurs if the expansion_factor is less than or equal to 0.
expansion_unitlessbool: When unitless, the distance by which the extent expands is the factor multiplied by the longer dimension (X or Y distance) of the expanded object/net.
use_round_cornerbool: Whether to use round or sharp corners. For round corners, this returns a bounding box if its area is within 10% of the rounded expansion’s area.
num_incrementsint: Number of iterations desired to reach the full expansion.

Returns:

PolygonData

Notes

Method returns the expansion of the contour, so any voids within expanded objects are ignored.

Layout.convert_primitives_to_vias(primitives, is_pins=False)#

Convert a list of primitives into vias or pins.

Parameters:

primitiveslist[Primitive]: List of primitives to convert.
is_pinsbool, optional: True for pins, false for vias (default).

Layout.find_net_by_name(value: str)#

Find a net object by name

Parameters:

valuestr: Name of the net.

Returns:

Layout.find_component_by_name(value: str) → pyedb.dotnet.database.cell.hierarchy.component.EDBComponent | None#

Find a component object by name. Component name is the reference designator in layout.

Parameters:

valuestr: Name of the component.
Returns
——-

Layout.find_padstack_instances(aedt_name: str | list[str] = None, component_name: str | list[str] = None, component_pin_name: str | list[str] = None, net_name: str | list[str] = None, instance_id: int | list[int] = None) → list[pyedb.dotnet.database.edb_data.padstacks_data.EDBPadstackInstance]#

Finds padstack instances matching the specified criteria.

This method filters the available padstack instances based on specified attributes such as aedt_name, component_name, component_pin_name, net_name, or instance_id. Criteria can be passed as individual values or as a list of values. If no padstack instances match the criteria, an error is raised.

Parameters:

aedt_nameUnion[str, List[str]], optional: Name(s) of the AEDT padstack instance(s) to filter.
component_nameUnion[str, List[str]], optional: Name(s) of the component(s) to filter padstack instances by.
component_pin_nameUnion[str, List[str]], optional: Name(s) of the component pin(s) to filter padstack instances by.
net_nameUnion[str, List[str]], optional: Name(s) of the net(s) to filter padstack instances by.
instance_idUnion[int, List[int]], optional: ID(s) of the padstack instance(s) to filter.

Returns:

List: A list of padstack instances matching the specified criteria.
