@Tim Edwards Do you know which metal stack from https://gf180mcu-pdk.readthedocs.io/en/latest/analog/layout/inter_specs/inter_specs_3.html we are using in the Efabless / Google open mpw program on GF180MCU?

3.20 1P5M TM 9KA with MIM option B. https://gf180mcu-pdk.readthedocs.io/en/latest/analog/layout/inter_specs/inter_specs_3_20.html

Is that gf180mcuC @Tim Edwards?

Yes, it is.

@Tom the open_pdks Makefile has neat documentations about the variants: https://github.com/RTimothyEdwards/open_pdks/blob/master/gf180mcu/Makefile.in#L58

Thank you for pointing me to that @proppy
