Call¶

class Call(subroutine, value_dict=None, name=None)[source]¶

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.

নোট

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

প্যারামিটার

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.

রেইজেস

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.
