generate_routing_passmanager(routing_pass, target, coupling_map=None, vf2_call_limit=None, backend_properties=None, seed_transpiler=None, check_trivial=False, use_barrier_before_measurement=True)

Generate a routing PassManager

Parameters

• routing_pass (TransformationPass) – The pass which will perform the routing
• target (Target) – the Target object representing the backend
• coupling_map (CouplingMap) – The coupling map of the backend to route for
• vf2_call_limit (int) – The internal call limit for the vf2 post layout pass. If this is None the vf2 post layout will not be run.
• backend_properties (BackendProperties) – Properties of a backend to synthesize for (e.g. gate fidelities).
• seed_transpiler (int) – Sets random seed for the stochastic parts of the transpiler.
• check_trivial (bool) – If set to true this will condition running the VF2PostLayout pass after routing on whether a trivial layout was tried and was found to not be perfect. This is only needed if the constructed pass manager runs TrivialLayout as a first layout attempt and uses it if it’s a perfect layout (as is the case with preset pass manager level 1).
• use_barrier_before_measurement (bool) – If true (the default) the BarrierBeforeFinalMeasurements transpiler pass will be run prior to the specified pass in the routing_pass argument.

Returns

The routing pass manager

Return type
