ltspice - How to use .step param with more than two parameters in LTSpiceIV

I need to do three transient simulations with different values of certain resistors (conveniently called R1 and R2) in each. What I mean to do exactly is this:

• Sim. 1: R1 = 1 k\$\Omega\$, R2 = 10 k\$\Omega\$


• Sim. 2: R1 = 1 M\$\Omega\$, R2 = 10 M\$\Omega\$



• Sim. 3: R1 = 1 k\$\Omega\$, R2 = 1 M\$\Omega\$

If there were just one resistor whose resistance to vary, then I would just set its resistance to "{r1}" (I use lower case letters to make it a different variable/parameter than R1) and use a command such as:

.step param r1 list 1k 1meg 1k

However, since I have to change two parameters (together) two times each, I have read here that (at least on LTSpiceIV) that a workaround to my problem could be using something like this:

.step param X list 1 2 3

.param r1 = table(X, 1k, 1meg, 1k)


.param r2 = table(X, 10k, 1meg, 10meg)

Upon doing the simulation, I get the following warnings:

WARNING: Can´t resolve .param r2 = table(X, 10k, 1meg, 10meg)
Select OK to continue the simulation with the default model or Cancel to quit now.

The same applies for r1.

For some reason, the simulation doesn´t "break" if I add one extra element to the table. In that case, the simulation takes too long, advancing more slowly every time, as it would never end. I have tried setting X to 0 1 2 instead of 1 2 3, but that does not work either.

Your help would be much appreciated.
