Gate Pin Group

class hal_py.GatePinGroup

A group of gate pins made up of a name, the pins, a pin order, and a start index.

property ascending

True if the pin order of a pin group comprising n pins is ascending (from 0 to n-1), False if it is descending (from n-1 to 0).

Type: bool

contains_pin(self: hal_py.GatePinGroup, pin: hal_py.GatePin) → bool

Check whether the pin group contains the given pin.

Parameters: pin (hal_py.GatePin) – The pin to check.
Returns: True if the pin group contains the pin, True otherwise.
Return type: bool

property direction

The direction of the pin group.

Type: hal_py.PinDirection

empty(self: hal_py.GatePinGroup) → bool

Check whether the pin group is empty, i.e., contains no pins.

Returns: True if the pin group is empty, False otherwise.
Return type: bool

get_direction(self: hal_py.GatePinGroup) → hal_py.PinDirection

Get the direction of the pin group.

Returns: The direction of the pin.
Return type: hal_py.PinDirection

get_id(self: hal_py.GatePinGroup) → int

Get the ID of the gate pin group. The ID is unique within a gate type.

Returns: The ID of the pin.
Return type: int

get_index(self: hal_py.GatePinGroup, pin: hal_py.GatePin) → int

Get the index within the pin group of the given pin.

Parameters: pin (hal_py.GatePin) – The pin
Returns: The index of the pin on success, -1 otherwise.
Return type: int

get_name(self: hal_py.GatePinGroup) → str

Get the name of the pin group.

Returns: The name of the pin group.
Return type: str

get_pin_at_index(self: hal_py.GatePinGroup, index: int) → hal_py.GatePin

Get the pin specified by the given index.

Parameters: index (int) – The index of the pin within the pin group.
Returns: The pin on success, None otherwise.
Return type: hal_py.GatePin or None

get_pins(self: hal_py.GatePinGroup, filter: Callable[[hal_py.GatePin], bool] = None) → List[hal_py.GatePin]

Get the (ordered) pins of the pin groups. The optional filter is evaluated on every pin such that the result only contains pins matching the specified condition.

Parameters: filter (lambda) – Filter function to be evaluated on each pin.
Returns: The ordered pins.
Return type: list[hal_py.GatePin]

get_start_index(self: hal_py.GatePinGroup) → int

Get the start index of the pin group. Commonly, pin groups start at index 0, but this may not always be the case. Note that the start index for a pin group comprising n pins is 0 independent of whether it is ascending or descending.

Returns: The start index.
Return type: int

get_type(self: hal_py.GatePinGroup) → hal_py.PinType

Get the type of the pin group.

Returns: The type of the pin.
Return type: hal_py.PinType

property id

The ID of the gate pin group. The ID is unique within a gate type.

Type: int

is_ascending(self: hal_py.GatePinGroup) → bool

Check whether the pin order of a pin group comprising n pins is ascending (from 0 to n-1) or descending (from n-1 to 0).

Returns: True for ascending bit order, False otherwise.
Return type: bool

is_ordered(self: hal_py.GatePinGroup) → bool

Check whether the pin group features an inherent order.

Returns: True if the pin group is inherently ordered, False otherwise.
Return type: bool

property name

The name of the pin group.

Type: str

property ordered

True if the pin group is inherently ordered, False otherwise.

Type: bool

property pins

The (ordered) pins of the pin groups.

Type: list[hal_py.GatePin]

size(self: hal_py.GatePinGroup) → int

Get the size, i.e., the number of pins, of the pin group.

Returns: The size of the pin group.
Return type: int

property start_index

The start index of the pin group. Commonly, pin groups start at index 0, but this may not always be the case. Note that the start index for a pin group comprising n pins is 0 independent of whether it is ascending or descending.

Type: int

property type

The type of the pin group.

Type: hal_py.PinType
