@User: There is a file in the PDK called "sky130.lib.spice". If you add a statement to the netlist (through a text block in xschem) with the syntax
.lib sky130.lib.spice tt
it will simulate at the
tt
corner. Other corners represented in the
sky130.lib.spice
file are
ss
,
ff
,
sf
,
fs
, for MOSFETs, and then
ll
,
hh
,
lh
, and
hl
for resistors and capacitors. The categories are set up to do resistor/capacitor corners at typical FET parameters, and to do FET corners at typical resistor/capacitor parameters. If you want to test both at the same time, e.g.,
sshh
or
ffll
, you can make a copy of
sky130.lib.spice
and define your own corners. The file is nothing but a bunch of
.include
statements, so you can pick and choose the ones you want for any corner simulation you want to define.
