- class Layout2qDistance(*args, **kwargs)¶
Evaluate how good the layout selection was.
Saves in property_set[『layout_score』] (or the property name in property_name) the sum of distances for each circuit CX. The lower the number, the better the selection. Therefore, 0 is a perfect layout selection. No CX direction is considered.
Return the name of the pass.
Run the Layout2qDistance pass on dag.
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.
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).
