Hi community, In Openroad, we are having a small problem for creating new nets (using the make_net command). It accepts only no-hierchical names, but when we want to assign a hierachical name (or ordered position in the design) to it, the net is not created. Do you know if this behavior is normal? Thank you in advance.

The OpenROAD DB is currently flat and doesn't understand hierarchy. I believe hierarchical netlists are flattened when they are read in. There is some ongoing work to add hierarchical support (see PR#4537). One of the only exceptions is that I believe if you use OpenSTA as a standalone, that supports hierarchical netlists. But there is no physical support in OpenSTA.
