Hi, When I ran the iccad2017 benchmark without fence region, the following problems occurred in three cases: They are pci_bridge32_b_md2, pci_bridge32_b_md3, def_perf_a_md2, but when I use the same lef def to run your ripple, it works fine.I don't know the reason, could you please explain it?

Thank you for your answer. I would like to ask another question, can you provide the Modified ISPD 2015 Benchmark used in your paper TCAD2021 on Pin-Accessible Legalization for Mixed-Cell-Height Circuits.
