"""
Begin building a new device based on all or some of the ports in the
source device. Do not include the source device; instead use it
to define ports (the "interface") for the new device.
The ports specified by `port_map` (default: all ports) are copied to
new device, and additional (input) ports are created facing in the
opposite directions. The specified `in_prefix` and `out_prefix` are
prepended to the port names to differentiate them.
By default, the flipped ports are given an 'in_' prefix and unflipped
ports keep their original names, enabling intuitive construction of
a device that will "plug into" the current device; the 'in_*' ports
are used for plugging the devices together while the original port
names are used for building the new device.
Another use-case could be to build the new device using the 'in_'
ports, creating a new device which could be used in place of the
current device.
Args:
source: A collection of ports (e.g. Pattern, Builder, or dict)
from which to create the interface.
library: Library from which existing patterns should be referenced, TODO
and to which new ones should be added. If not provided,
the source's library will be used (if available).
tools: Tool objects are used to dynamically generate new single-use
patterns (e.g wires or waveguides) while building. If not provided,
the source's tools will be reused (if available).
in_prefix: Prepended to port names for newly-created ports with
reversed directions compared to the current device.
out_prefix: Prepended to port names for ports which are directly
copied from the current device.
port_map: Specification for ports to copy into the new device:
- If `None`, all ports are copied.
- If a sequence, only the listed ports are copied
- If a mapping, the listed ports (keys) are copied and
renamed (to the values).
Returns:
The new builder, with an empty pattern and 2x as many ports as
listed in port_map.
Raises:
`PortError` if `port_map` contains port names not present in the
current device.
`PortError` if applying the prefixes results in duplicate port
names.

"""
Instantiate another pattern into the current device, connecting
the ports specified by `map_in` and renaming the unconnected
ports specified by `map_out`.
Examples:
=========
- `my_device.plug(lib, 'subdevice', {'A': 'C', 'B': 'B'}, map_out={'D': 'myport'})`
instantiates `lib['subdevice']` into `my_device`, plugging ports 'A' and 'B'
of `my_device` into ports 'C' and 'B' of `subdevice`. The connected ports
are removed and any unconnected ports from `subdevice` are added to
`my_device`. Port 'D' of `subdevice` (unconnected) is renamed to 'myport'.
- `my_device.plug(lib, 'wire', {'myport': 'A'})` places port 'A' of `lib['wire']`
at 'myport' of `my_device`.
If `'wire'` has only two ports (e.g. 'A' and 'B'), no `map_out` argument is
provided, and the `inherit_name` argument is not explicitly set to `False`,
the unconnected port of `wire` is automatically renamed to 'myport'. This
allows easy extension of existing ports without changing their names or
having to provide `map_out` each time `plug` is called.
Args:
other: An `Abstract` describing the device to be instatiated.
map_in: dict of `{'self_port': 'other_port'}` mappings, specifying
port connections between the two devices.
map_out: dict of `{'old_name': 'new_name'}` mappings, specifying
new names for ports in `other`.
mirrored: Enables mirroring `other` across the x or y axes prior
to connecting any ports.
inherit_name: If `True`, and `map_in` specifies only a single port,
and `map_out` is `None`, and `other` has only two ports total,
then automatically renames the output port of `other` to the
name of the port from `self` that appears in `map_in`. This
makes it easy to extend a device with simple 2-port devices
(e.g. wires) without providing `map_out` each time `plug` is
called. See "Examples" above for more info. Default `True`.
set_rotation: If the necessary rotation cannot be determined from
the ports being connected (i.e. all pairs have at least one
port with `rotation=None`), `set_rotation` must be provided
to indicate how much `other` should be rotated. Otherwise,
`set_rotation` must remain `None`.
Returns:
self
Raises:
`PortError` if any ports specified in `map_in` or `map_out` do not
exist in `self.ports` or `other_names`.
`PortError` if there are any duplicate names after `map_in` and `map_out`
are applied.
`PortError` if the specified port mapping is not achieveable (the ports
do not line up)

"""
Instantiate the device `other` into the current device, adding its
ports to those of the current device (but not connecting any ports).
Mirroring is applied before rotation; translation (`offset`) is applied last.
Examples:
=========
- `my_device.place(pad, offset=(10, 10), rotation=pi / 2, port_map={'A': 'gnd'})`
instantiates `pad` at the specified (x, y) offset and with the specified
rotation, adding its ports to those of `my_device`. Port 'A' of `pad` is
renamed to 'gnd' so that further routing can use this signal or net name
rather than the port name on the original `pad` device.
Args:
other: An `Abstract` describing the device to be instatiated.
offset: Offset at which to place the instance. Default (0, 0).
rotation: Rotation applied to the instance before placement. Default 0.
pivot: Rotation is applied around this pivot point (default (0, 0)).
Rotation is applied prior to translation (`offset`).
mirrored: Whether theinstance should be mirrored across the x and y axes.
Mirroring is applied before translation and rotation.
port_map: dict of `{'old_name': 'new_name'}` mappings, specifying
new names for ports in the instantiated device. New names can be
`None`, which will delete those ports.
skip_port_check: Can be used to skip the internal call to `check_ports`,
in case it has already been performed elsewhere.
