The Circuit Parameters view contains the following:

  Element   Description
Add parameter button. Click to add a new circuit parameter. You can also click in the first empty row in the Name column.
Remove selected parameters button. Select one or more parameters and click to remove them. You can also press Delete on the keyboard.
Move up button. Moves the selected parameters up in the table.
Move down button. Moves the selected parameters down in the table.
Place circuit parameter legend button. Places a list of circuit parameters on the workspace.
 

Export button. Displays a list of export options. Select one of the following:

Copy to clipboard—Copies the selection onto the clipboard. (You can only paste the contents of the clipboard into a text editor, not Multisim.)

Export to text file—Displays a Save dialog where you save the selection as a text file.

Export to CSV file—Displays a Save dialog where you save the selection as a comma separated value file.

Export to Excel—Opens the selection in a Microsoft Excel spreadsheet. You must have Excel installed to use this function.

Print—Displays the Print dialog box where you set up and print the selection.
Table Name column—A circuit parameter name may contain letters, numbers and underscores but no other symbols. It must not start with a number and is not case sensitive.

Expression column—This is the value of the circuit parameter. It can be a simple numeric value or a mathematical expression consisting of numeric constants, various functions and operators, and other circuit parameters.

The expression may not contain references to voltages or currents.

Circuit parameters maintain constant values for the each simulation run.

  You can use the ABM sources to adjust voltage or current variables.
Preview column—The preview column shows the numeric result of evaluating the expression. It provides a simple way of validating any expression, including those formed by using circuit parameters within expressions of other circuit parameters. Note that the displayed result is used in the simulation only if the parameter, or the parameters it depends on, is not being overridden by hierarchy or analysis. For example, assume you have entered the following two parameters:
If you run an interactive simulation or perform DC Operating Point or Transient analysis, during the simulation circuit parameters a and b will have values 1 and 3 respectively. However, if you run a Parameter Sweep on circuit parameter a, during the simulation, the values of a and b will be overridden by the values specified in the parameter sweep.
Comment column—Type optional notes here, for example, to describe where you are using the expression.
