这个工艺没做过,有些工艺是不需要
像SMIC 65nm/55nm就需要,在Standard Cell Library Databook中有记载
The standard cell library contains one NWELL/Substrate Tie Cell: FILLTIEHS. This standard cell library does not have well or substrate ties inside the cells. It is required to tie NWell to VDD and substrate to VSS before place-and-route using the FILLTIEHS cells
