Parameter Sweep: run every simulation with another parameter
value.
Curve Fitting: vary parameters until the model response equals
measured response.
Sensitivity Analysis: Which parameter variation effects the model
output the most?
Monte Carlo Analysis: The statistical output after 1000 simulation
runs.

During simulation, the time domain behavior of a model is calculated.
Based on this time-domain behavior, the model can be analyzed.
A set of powerful methods for time domain analysis is available
in 20-sim.
Parameter Sweeps
Parameter sweeps are multiple simulations with a variation of
parameter values. It is a quick method to see how your model behavior
depends on the parameter values.
Parameter Optimization
Using Optimization, you can maximize the performance of your
model by varying specified model parameters. Predefined or user
defined cost functions can be used as a measure of model performance.
A number of well known optimization methods can be used to minimize
or maximize these cost functions.

Curve Fitting
With Curve Fitting you can fit model performance to a given result
by variation of parameters. It is a very useful method to optimize
model parameters when measurement data is available.
Sensitivity Analysis
Sensitivity Analysis is used to investigate the effect of parameter
variation on model performance. The change in performance divided
by the parameter change is plotted in a table. Sensitivity Analysis
is a well-known method in production engineering to find critical
systems tolerances in early stages of the design
Monte-Carlo Analysis
With Monte-Carlo Analysis, you can perform a predefined number
of simulation runs with statistical variation of parameter values.
Results can be shown as histograms or inspected numerically. Monte
Carlo Analysis is a powerful method to find out worst case model
behavior.
Variation Analysis
With Variation Analysis you can find the statistical range of
parameter values that yield a model with a certain performance
level. Variation Analysis is a powerful method to find a measure
for system tolerances in the early stage of the design.
