Hello all, I am trying to run LVS for a 25-bit shift register flip flop. When I run the netgen using this command

netgen -batch lvs Flippy.spice Flippy_layout.spice /foss/pdks/sky130A/libs.tech/netgen/sky130A_setup.tcl

I get these property errors:

~/shift_register >  netgen -batch lvs Flippy.spice Flippy_layout.spice /foss/pdks/sky130A/libs.tech/netgen/sky130A_setup.tcl
