in anticipation of having the mc_pr_switch
for process variation) (it seems that if I set this parameter =0 outside of the testbench then I cannot override the parameter from within the testbench). My script is, I think, doing the right thing, but the process parameters that get varied aren't in the path of sky130.lib.spice
, but seem to be in the path parameters/montecarlo.spice
. So @User is right that to get the process variation, it's probably necessary to set up another section in sky130.lib.spice
called mc
or tt_mc
or whatever, and have it include montecarlo.spice
and a few others that I think are related, like r+c.mrp1monte.spice
. I'm still trying to figure out how to do this.Tim Edwards

followed by montecarlo.spice
, in place of using .lib sky130.lib.spice
. The top of my testbench file looks like:
.param mc_mm_switch=0
.param mc_pr_switch=1
.option SEEDINFO
.option SEED=random
.include /usr/share/pdk/sky130A/libs.tech/ngspice/parameters/critical.spice
.include /usr/share/pdk/sky130A/libs.tech/ngspice/parameters/montecarlo.spice
I think it would be simpler for most people if I just added a block called mc
to sky130.lib.spice
