in your netlist and replace with these lines:
.param mc_mm_switch=0
.param mc_pr_switch=0
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/corners/`tt`.spice
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/r+c/res_`typical`__cap_`typical`.spice
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/r+c/res_`typical`__cap_`typical`__lin.spice
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/corners/`tt`/specialized_cells.spice
In above lines put the correct path to your libs.tech installation (the above is the path on my system).
then replace the tt
with one of ss
, sf
, fs
, ff
for transistor corners.
and replace typical
with high
or low
for resistor and capacitor corners. First typical
applies to resistor, second one for capacitors.
I have not tried mixing transistor and res/cap corners, but it should work.
Example: slow transistor corner, high resistances, low capacitances:
.param mc_mm_switch=0
.param mc_pr_switch=0
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/corners/`ss`.spice
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/r+c/res_`high`__cap_`low`.spice
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/r+c/res_`high`__cap_`low`__lin.spice
.include /home/schippes/share/pdk/sky130A/libs.tech/ngspice/corners/`ss`/specialized_cells.spiceMudasir
