Call

class Call(subroutine, value_dict=None, name=None)

Bases: Instruction

Pulse Call instruction.

The Call instruction represents the calling of a referenced subroutine (schedule). It enables code reuse both within the pulse representation and hardware (if supported).

Define new subroutine.

Nota

Inline subroutine is mutable. This requires special care for modification.

Parámetros

• subroutine (Union[Schedule, ScheduleBlock]) – A program subroutine to be referred to.

• value_dict (Optional[Dict[ParameterExpression, Union[ParameterExpression, float]]]) – Mapping of parameter object to assigned value.

• name (Optional[str]) – Unique ID of this subroutine. If not provided, this is generated based on the subroutine name.

Muestra

PulseError – If subroutine is not valid data format.

Methods

append	Return a new Schedule with schedule inserted at the maximum time over all channels shared between self and schedule.
assigned_subroutine	Returns this subroutine with the parameters assigned.
ch_duration	Return duration of the supplied channels in this Instruction.
ch_start_time	Return minimum start time for supplied channels.
ch_stop_time	Return maximum start time for supplied channels.
draw	Plot the instruction.
insert	Return a new Schedule with schedule inserted within self at start_time.
is_parameterized	Return True iff the instruction is parameterized.
shift	Return a new schedule shifted forward by time.
