### steps
1. initial synth/timing
* initialize floorplan (initialize_floorplan)
* gate_resizer (multiple commands)
* can set estimated wire rc per layer
* can add buffers on I/O
* repairs fanouts/caps/etc.
* STA can run before and/or after this
* OpenSTA (sta)
2. full PD
* macro place (macro_placement)
* tapcell/endcap (tapcell)
* global placement (global_placement)
* detailed placement (legalize_placement)
* CTS (clock_tree_synthesis)
