You can define several .STEP commands with an unlimited number of nesting levels. Multiple
sweeps can change concurrently.
• This example specifies that the value of resistor R22 will be swept from 20k to 100k,
with an increment of 1k => 81 points, parameter COX will be swept from 0.4m to 0.3m
at the same time with 81 increment points. R22 and COX are varying together and 81
simulations are performed.
.STEP E(R22,R) 20k 100k 1k M(MOS1,COX) 0.4m 0.3m
• This examples specifies that 81 simulations for the first .step, 31 simulations for the
second .step, with a total of 81 x 31 simulations performed.

• In this example 3 simulations will be performed. The first one with p1=1 and mylib
using variant min, the second one with p1=1.5 and mylib using variant typ, and the third
one with p1=2 and mylib using variant max.
.STEP P(p1) 1 2 0.5 LIB(mylib) LIST min typ max
• In the following example, two simulations will be performed. The first with R1 value of
20k, TEMP is 27 and uses the LIB variant typ for file corna.lib. The second with R1
value set to 10k, a TEMP value of −40 and the LIB variant fast of the file corna.lib.
