Hello @Amro Tork @Tim Edwards, any idea why this 1T1C layout detects the capacitor as a device when I run LVS from Klayout GUI and it doesn't detect it when I run it from this repo: https://github.com/efabless/globalfoundries-pdk-libs-gf180mcu_fd_pv/tree/main/klayout/lvs ? As a side note the capacitance detected from the schematic using Klayout GUI is 0.2f when it should be 50f I'm using gf180mcuD, the log file generated from the repo is not very useful, it shows the Klayout version , the path used and the date and time. Any help is appreciated

I expect it's the use of the generic cap model in the schematic that's the problem. The MiM cap models differ significantly depending on the process variant, and the
cap_mim_2f0fF
model is not specific to a process variant and I don't know what process variant (if any) it corresponds to. There is a separate model file
sm141064_mim.ngspice
that defines process-specific MiM cap models, and the one for the
gf180mcuD
is called
cap_mim_2f0_m4m5_noshield
. That is the model that you should be using in the schematic, and the model which I suspect is being extracted from layout (although hard to verify because you did not post a layout-extracted netlist).

@Sebastian Sanchez Could you please open an issue on the repo above?
