Enhance read_spef to support hierarchical stitching of parasitics #121

Closed tspyrou closed 1 year ago

tspyrou commented 1 year ago

The delete_after_reduce option should be ignored on SPEF annotations which have terminal points on hierarchical nodes until the net is completely annotated and then stitched. https://github.com/The-OpenROAD-Project/OpenSTA/issues/120 will also be important to ensure all nets and up with complete parasitics.
