Only top-level sub-schedules are aligned. If sub-schedules are nested, nested schedules are not recursively aligned.

**Parameters**

**schedule** ([*Schedule*](/docs/api/qiskit/1.1/qiskit.pulse.Schedule "qiskit.pulse.schedule.Schedule")) – Schedule to align.

**Returns**

Schedule with reallocated instructions.

**Return type**
