DesignHierarchy

class keysight.ads.de.DesignHierarchy

__init__(unused: InvalidCall, *args, **kwargs) → None: Return an error about attempts to initialize objects that don’t support initialization.

property depth: int

property design: Design

property is_at_root: bool

is_primitive_instance(inst: Instance) → bool

parent_designs() → Iterable[Design]

parent_instance_names() → Iterable[str]

pop() → DesignHierarchy

push_instance_for_reading(inst: Instance) → DesignHierarchy

Push into the instance in read-only mode.

Modifications of a read-only design may only be saved to a new cellview.

push_instance_for_writing(inst: Instance) → DesignHierarchy: Push into the instance in edit mode.

property root_design: Design

traverse_instances(include_implicit: bool = False, include_pin_insts: bool = True, limit_box: BoxF | None = None, allow_box_intersect: bool = True) → Iterable[tuple[Instance, DesignHierarchy]]

Iterate through design hierarchically.

Parameters:

include_implicit (bool) – Defaults to false and will include implicit shapes individually when set. For example bus nets will show up as one when set to false, but will be enumerated individually when set to True.
include_pin_insts (bool) – Defaults to True and will include PinInst objects during the traversal.
limit_box (BoxF) – Default to None and when set will limit the traversal to the specified region in user units.
allow_box_intersect (bool) – Defaults to True and when set includes instances that intersect the specified box to be part of the traversal, otherwise only instances wholly inside the box are returned.

Example

>>> for x, _ in topdsn.get_hierarchy_for_netlist().traverse_instances(include_implicit = True):
...     print(f"Inst = {x}")
