Hi All, I just installed the sky130 PDK on a ubuntu virtual machine using

make setup

from the caravel_user_project make file. The problem was that ngspice complained about missing a

corners/tt.spice

file when I ran the example tes_nmos schematic in xschem. I checked the

sky130A/libs.tech/ngspice

directory and I was indeed missing the

corners/tt.spice

file and the

tt

section of

sky130.lib.spice

was including this file. I manually reinstalled the PDK with the make command

make pdk-with-sram

. The

sky130A/libs.tech/ngspice

directory now contains corners folder along with some other directories. The simulation works fine in this case. The original

make pdk-with-valore

command in the make setup did not create the corners and other directories in the

sky130A/libs.tech/ngspice

folder? Did I miss some configuration during the installation?

I don't know anything about the Volare setup. That was done by @donn.
