Parameter Defaults Tab (Edit Component)

This tab displays and sets the default values for component parameters for general analysis (Value option) or statistical analysis (Statistics option). You can also add, edit, or remove properties.

Value Option (Parameter Defaults Tab)

Click Value to list, display, and set the default values for the following component parameters used during general analysis:

• Name – Display the names of component parameters. Names can be edited for case only.
• Value – Change the initial values of parameters.
• Unit – Set the unit of measure for the parameter value.
• Evaluated Value – This read-only column displays the evaluated value of the parameter.
• Description – Enter a description for the parameter.
• Netlist Unit – Set the unit of measure used when the parameter is netlisted.
• Callback – Associate a callback script with the parameter.
• Read-only – Choose whether the parameter settings can be changed.
• Hidden – Choose whether the parameter is hidden by default.
• Property Type – Display the type (for example, Real) for generic properties.
• Show Pin – Show a pin for the property on the component’s symbol.
• Sweep – Enable the value for sweep.
• Default SDB – Enable the value to be stored in the project SDB.

Statistics Option (Parameter Defaults and Quantities Tabs)

Click Statistics to list, display, and set the values for the following component parameters applicable to statistical analysis:

• Name – Display the names of component parameters.
• Include – Choose whether the associated component parameter will be varied during statistical analysis. Select Include for each parameter you want Twin Builder to vary during statistical analysis.
• Distribution – Display and choose whether the parameter value distribution is Uniform, Gaussian, lognormal, or user-defined. To change the distribution setting, click the cell to display and select an option.
• Distribution Criteria – Click the button in this column to open the Edit Distribution dialog box, in which you can set distribution criteria. The Distribution Type drop-down menu displays whether the distribution is Uniform or Gaussian, and you can specify values for Cutoff Probability, Mean, and Tolerance. Units for Mean and Tolerance can be set using their adjacent drop-down menus.
