I am trying to setup yosys mapping files for ORFS flow similar to sky130hd <https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/flow/platforms/sky130hd/cells_clkgate_hd.v>. Can anyone confirm for gf180 is clock gate cell from this list <https://gf180mcu-pdk.readthedocs.io/en/latest/digital/standard_cells/gf180mcu_fd_sc_mcu9t5v0/index.html>?

similarly which latches to use for gf180?
For sky130 took reference <https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/flow/platforms/sky130hd/cells_latch_hd.v>

What is Linen?
