Hi I'm trying to run a magic layout extracted spice file in ngspice using sky130 pdk, but I'm running into an error which says the model_name is not found . I'm attaching a screenshot of ngspice error window and the spice file. Can anyone point me in the right direction please?

You should probably delete the extracted files and re extract the magic layout with following commands in order in tcl window. 1. extract path extfiles 2. extract all 3. ext2spice lvs 4. ext2spice -p extfiles This should resolve the error most probably.

@Harish Kumar Dharavath It looks like maybe the extracted netlist has been modified. The

.option scale=10m

is usually not part of the extracted netlist. Have you modified the

l

and

w

values? Does the scale effect the device sizes in the

.lib

file?
