ALAPScheduleAnalysis

class ALAPScheduleAnalysis(*args, **kwargs)

Bases: BaseScheduler

ALAP Scheduling pass, which schedules the stop time of instructions as late as possible.

See the Scheduling Stage section in the qiskit.transpiler module documentation for the detailed behavior of the control flow operation, i.e. c_if.

Scheduler initializer.

Parameters

• durations -- Durations of instructions to be used in scheduling

• target -- The Target representing the target backend, if both durations and this are specified then this argument will take precedence and durations will be ignored.

Methods

name	Return the name of the pass.
run	Run the ALAPSchedule pass on dag.

Attributes

CONDITIONAL_SUPPORTED = (<class 'qiskit.circuit.gate.Gate'>, <class 'qiskit.circuit.delay.Delay'>)

is_analysis_pass

Check if the pass is an analysis pass.

If the pass is an AnalysisPass, that means that the pass can analyze the DAG and write the results of that analysis in the property set. Modifications on the DAG are not allowed by this kind of pass.

is_transformation_pass

Check if the pass is a transformation pass.

If the pass is a TransformationPass, that means that the pass can manipulate the DAG, but cannot modify the property set (but it can be read).
