kqcircuits.util.instance_hierarchy_helpers

class kqcircuits.util.instance_hierarchy_helpers.InstanceHierarchy(instance: Instance, trans: DCplxTrans, parent_instances: List[Instance], top_cell: Cell)[source]

Bases: object

Data structure holding the instance hierarchy of a single cell instance

instance: Instance

trans: DCplxTrans

parent_instances: List[Instance]

top_cell: Cell

kqcircuits.util.instance_hierarchy_helpers.get_cell_instance_hierarchy(layout: Layout, cell_index: int) → List[InstanceHierarchy][source]

Find all instances of a cell and their transforms (DCplxTrans) in the global coordinate system. Resolves the full cell hierarchy.

Parameters:

layout – Layout object
cell_index – Cell index of the cell to find instances of

Returns: list of InstanceHierarchy structrures describing the cell hierarchy of each instance

kqcircuits.util.instance_hierarchy_helpers.formatted_cell_instance_hierarchy(inst_data: InstanceHierarchy) → str[source]

Create formatted list showing the instance hierarchy of all instances of a cell, including the global transformation of the instance and the instance names along the hierarchy if they are defined.

Parameters:

layout – Layout object
cell_index – Cell index of the cell to find instances of

Returns: formatted string (multiple lines)
