Under help this statement is made
"You can include variances in your simulations that are introduced as a result of component tolerances. For example, a 1 kohm resistor with a 10% tolerance could vary plus or minus 100 ohms, which would in turn affect the results of the simulation."
but what does that mean? Does the simulator Monte Carlo a set of tolerances to use? Does the simulator do some sort of extreme value analysis to give the largest transient response?
If I select "use tolerances" and then run the simulation with the network analyzer attached, the stability plot changes. What is being varied to make this change?

Hi,
When you turn on the Use Tolerance under the Simulate menu, components that will change value are resistors, inductors and capacitors.
You can define the component tolerance on the Spreadsheet view by selecting the "Component" tab, there should be a "Tolerance" column.
Each time you run the simualation, the component with tolerance will change randomly. A 1K resistor can be anywhere between 950- 1050 ohm for each run.
