ASAPScheduleAnalysis
class ASAPScheduleAnalysis(durations)
Bases: qiskit.transpiler.passes.scheduling.scheduling.base_scheduler.BaseScheduler
ASAP Scheduling pass, which schedules the start time of instructions as early as possible..
See BaseScheduler for the detailed behavior of the control flow operation, i.e. c_if.
Scheduler initializer.
Parameters
durations (InstructionDurations) – Durations of instructions to be used in scheduling
Methods
name
ASAPScheduleAnalysis.name()
Return the name of the pass.
run
ASAPScheduleAnalysis.run(dag)
Run the ASAPSchedule pass on dag.
Parameters
dag (DAGCircuit) – DAG to schedule.
Returns
A scheduled DAG.
Return type
Raises
- TranspilerError – if the circuit is not mapped on physical qubits.
- TranspilerError – if conditional bit is added to non-supported instruction.
Attributes
CONDITIONAL_SUPPORTED
Default value: (<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).
