Advanced Analysis is an add-on program for PSpice A/D and PSpice Simulator. You can use Advanced Analysis tools to improve the circuit performance, reliability, and yield.

Monte Carlo predicts the behavior of a circuit statistically when part values are varied within their tolerance range. Monte Carlo also calculates yield, which can be used for mass manufacturing predictions.

**You can use Monte Carlo for: **

- Calculating yield based on your specs
- Integrating measurements with graphical displays
- Displaying results in a probability distribution function (PDF) graph
- Displaying results in a cumulative distribution function (CDF) graph
- Calculating statistical data
- Displaying measurement values for every Monte Carlo run

**Some important points to remember while running Advanced Analysis Monte Carlo: **

- Start with enough runs to provide statistically meaningful results.
- Specify a larger number of runs for a more accurate graph of performance distribution. This more closely simulates the effects of mass production.
- Start with a different random seed value if you want different results.
- Set the graph bin number to show the level of detail you want. Higher bin numbers show more detail but need more runs to be useful.
- If you are planning an analysis of thousands of runs on a complex circuit, you can turn off the simulation data storage option to conserve disk space. However, at this setting, the simulation will run slower.

To turn off data storage:

- From the Advance Analysis menu select Edit / Profile Settings/ Simulation
- From the Monte Carlo field, select Save None.

The simulation data will be overwritten by each new run. Only the last run’s data will be saved.

**You can review Monte Carlo results on two graphs and two tables:**

- Probability density function (PDF) graph
- Cumulative distribution function (CDF) graph
- Statistical Information table, in the Statistics tab
- Raw Measurements table, in the Raw Measurement tab
