Returns: A list containing the name of item and the item itself ([item.name, item]).
Return type: list

Example

>>> import laygo2
>>> from laygo2.object.database import Design
>>> from laygo2.object.physical import Rect, Pin, Instance, Text
>>> # Create a design
>>> dsn = Design(name="mycell", libname="genlib")
>>> # Create layout objects
>>> r0 = Rect(xy=[[0, 0], [100, 100]], layer=["M1", "drawing"])
>>> p0 = Pin(xy=[[0, 0], [50, 50]], layer=["M1", "pin"], name="P")
>>> i0 = Instance(libname="tlib", cellname="t0", name="I0", xy=[0, 0])
>>> t0 = Text(xy=[[50, 50], [100, 100]], layer=["text", "drawing"], text="T")
>>> dsn.append(r0)
>>> dsn.append(p0)
>>> dsn.append(i0)
>>> dsn.append(t0)
>>> print(dsn)
