@tnt Are you only getting
Implicit pin
warnings for
decap
and
fill
cells or do you get them for all cells? What commit are you using for
skywater-pdk/libraries/sky130_fd_sc_hd/latest
? I'm wondering if these cells might be missing from the cdl or spice libraries under
sky130a/libs.ref/sky130_fd_sc_hd
?

Only decap and fill.
It seems it might be using the wrong verilog file. The spice input actually has pins for those cells.
Ok, yeah it was using the wrong verilog file cause of combination of my custom flow script and the recent change in openlane ...

Great! Good luck with the antennas.
