Monte Carlo Analysis

It is used to calculate accurate component parameter values for a given output at a given instant of time. We will study the performance of the circuit
AMPLIF.EPB.
1. Right click and select the
Monte Carlo Voltage option tool from the function tool Reference Points. Define the reference point by clicking on the wire connected to the transistor Collector pin.
1. Click Analysis in the main menu. A window Setup Simulation Parameters opens with the option Analysis being highlighted on the left side of the window by default. Set the parameters by selecting GENERAL SETTINGS from the tree view on the left side of the window. Now, select the
Monte Carlo Analysis option.
2. We will select the Component RB1. Move the cursor over the resistor RB1 and click the left mouse button. The selected component name and parameter name appears in the dialog box. Selected resistor has only one parameter, and is automatically selected. If we have more parameters, we will have to specify the parameter of the component, e.g., a transistor, from the drop down ‘Parameter Value’. We may conduct the analysis when the parameter of one circuit element is varied keeping the parameter of another circuit element constant, through out a range of values. In that case, check the check box Component (2) and set its parameters. For more details, refer main Help.
3. Set the Tolerance to be 10% and No. of samples 10. Tolerance specifies the percentage range of variation of component parameters. No. of Samples specifies the number of iterations within the output range for which analysis is to be carried out. Time specifies an instant of time at which the accurate parameter value is to be calculated for obtaining the specified output. Set it as 10ms.
4. Click ACCEPT button to automatically switch to Analysis option. Check
Monte Carlo Analysis check box. Now click START button for analysis to take place.
5. The results are displayed in a text file.
