7 Monte Carlo Analysis Back to top

7.1 What is Monte Carlo Analysis? Back to top

Monte Carlo Analysis helps users to see the overall effect when some components have deviation to its marked value.

7.2 How to start Monte Carlo as a standalone tool Back to top

Click on "Monte Carlo" on the left main menu to start Monte Carlo Analysis.

7.3 Introduction to Interface (stand alone tool) Back to top

Since Monte Carlo Analysis is not a stand alone tool:
Users must initialize a design before using Monte Carlo Analysis.
Click the [Topology] button to start a design from Topology.
For details about starting a design from topology, please refer to Session 2.2.2--Start a Design from Topology.
If users want to start a design via another method, please refer to Session 2.2--Start a power supply design.

After initializing a design, please refer to Session 7.5--Introduction to Interface (with topology) for details on how to use this tool.

7.4 How to start Monte Carlo (with topology) Back to top

Please refer to Session 7.2-- How to start Monte Carlo as a standalone tool.

7.5 Introduction to Interface (with topology) Back to top

7.5.1 Top Bar Back to top

Please refer to Session 9.3.7--Top bar.

7.5.2 No. of Sample Back to top

Users can modify the number of sample in the position as shown below.

7.5.3 No. of variating component Back to top

No. of variating component means the number of components which had been enabled for Monte Carlo Analysis.

7.5.4 Monte Carlo Analysis Result Back to top

The result of the Monte Carlo Analysis is shown in this area.
Resulting loss/Vo values are divided by the number of bin to construct corresponding histograms.

Users can change the number of bin. The result will be recalculated after clicking [Recalculate] at the top right corner of the top bar.

7.5.5 List of enabled Monte Carlo Analysis components Back to top

In this list, users can modify the details of the Monte Carlo Analysis of the component.

1 . Click the blue button with the designator to enter the Component Finder page. For more details, please refer to Session 3--Component Finder.

2. In the Detail column, it shows the details of the Monte Carlo Analysis of the component. Users can modify these and then click [Recalculate] to update the result.

3. To disable a component from Monte Carlo Analysis, uncheck the box on the right, then click [Apply] to update the result.

7.5.6 Component List of all components in design Back to top

Click the blue button with the designator to enter the Component Finder page. For more details, please refer to Session 3--Component Finder.

To enable a component for Monte Carlo Analysis, check the box on the right, then click [Apply] to update result.
