The various analyses that can be performed by the Mixed Simulator are defined in this dialog. The dialog box has four tabs: in the first tab you can set the analyses to be performed, in the second you can define any global parameters, in the third tab you can set the options of the simulator, in the fourth tab are listed the defined I/O models.

Analyses

In this tab you can set the analyses to be performed. Each analysis is configured in a different dialog box and it is possible to define several versions of the same analysis by setting different parameters for each of them.

To define an analysis

Choose the Add button. A dialog box opens in which you can choose which analysis to perform. You can also specify a brief description of the type of analysis.
Select the type of analysis and click on Ok. The dialog box for configuring the analysis parameters opens.
Set the parameters to configure the analysis.
Close the dialog box by clicking on the Ok button.

The following basic analysis types are supported, click a link to learn more about that analysis type:

Operating Point Analysis
Transient Analysis
Interactive Transient Analysis
DC Sweep Analysis
AC Small Signal Analysis
Noise Analysis
Pole-Zero Analysis
Transfer Function Analysis
Distortion Analysis

To run an analysis

Select one of the defined analyses.
Choose the Run button.

To duplicate an analysis

Select one of the defined analyses.
Choose the Duplicate button. The dialog box for configuring the analysis parameters opens.
Enter a brief description of the type of analysis. The text entered is the title of the document in which the simulation results will be stored.
Set the parameters to configure the analysis.
Close the dialog box by clicking on the Ok button.

Global Parameters

In this tab you can specify any global parameters that can be used in the description of the circuit instead of numerical values. Parameters can be constants or expressions, which in turn can include other parameters. For a list of operators, constants and functions that can be used in an expression, see Behavioral Modeling Expressions.

To add a global parameter

Choose the Add button. A new line is added with the active entry cursor in the Name box.
Specify the parameter name.
Click in the Value box and enter the parameter value. The value can be either a constant or a numerical expression. Note that in this case, unlike all other cases where an expression can be used, it is not necessary to enclose the expression in curly brackets.

To delete a parameter

Select the parameter.
Choose the Delete button.

Options

This tab lists the options of the simulator. Each line shows the name and current value. For a complete list of options, see Simulator Options in the Simulator Reference Guide.

Note:
The options set in this tab apply to all defined analyses. In addition, you can redefine the value of some options locally for each analysis by clicking the Options button in the analysis-specific dialog box.

I/O Models

This tab lists all defined I/O models. The I/O models are used to interface the digital devices with the analog circuits and describe the load and drive characteristics of the digital devices.

Tip:
For digital devices, the I/O model can be selected in the symbol properties dialog box. Activate the Attributes tab and select the I/O model in the IOMODEL attribute of the SPICE category.
