Variables

Several variable names are reserved by IC-CAP and cannot be assigned as user-defined variables. You can assign values to reserved variables and define your own variables at several different levels (variables at lower levels inherit their values from variables above them):

    • Global   * DUT level
    • Model level   * Setup level

You define global variables through the IC-CAP Main window. These variables apply to all Models, DUTs, and Setups unless you explicitly set the variables differently at the Model, DUT, or Setup level.

You define Model, DUT, and Setup variables through the Model window:

    • Model variables apply to all DUTs and Setups of that Model unless you explicitly set the variables differently for individual DUTs and/or Setups.
    • DUT variables apply to all Setups of that DUT unless you explicitly set the variables differently for individual Setups.
    • Setup variables apply only to that Setup.

Assigning Values

Assigning Values to Global Variables

To assign values to global variables:

In the Main window, choose Tools > System Variables and the Variables window appears.

    • To create user-defined variables:
Type the names and values in the fields provided. Additional fields appear as you specify values.

    • To assign values to supplied variables:

  1   Type their names and values in the System Variables window or click System Variables and a dialog box appears.

  2   Select the appropriate category and the variables in that category are displayed.

  3   Click to select a variable and a description of that variable is displayed.

  4   Type the appropriate value in the Value field and click Apply. The variable name and its value appear in the Variables window.

  5   Continue assigning variable values as needed. When you are finished, click OK.

Assigning Values to Model Variables

    • To define variables at the model level:
Click to open the Model Variables folder.

    • To create user-defined variables:
Type the names and values in the fields provided. Additional fields appear as you specify values.

    • To assign values to supplied variables:

  1   Type their names and values in the System Variables window or click System Variables and a dialog box appears.

  2   Select the desired Variable Type and a list of variables of that type appears.

  3   Select the variable. A description is displayed.

  4   Enter the desired value for that variable and click Apply.

  5   Continue defining variables in this manner, clicking Apply to effect each change. When you are through defining variables, click OK.

Assigning Values to DUT Variables

To define variables for a DUT:

Click to open the DUT Variables folder.

    • To create user-defined variables:
Type the names and values in the fields provided. Additional fields appear as you specify values.

    • To assign values to supplied variables:

  1   Type their names and values in the System Variables window or click System Variables and a dialog box appears.

  2   Select the desired Variable Type and a list of variables of that type appears.

  3   Select the variable. A description is displayed.

  4   Enter the desired value for that variable and click Apply.

  5   Continue defining variables in this manner, clicking Apply to effect each change. When you are through defining variables, click OK.

Assigning Values to Setup Variables

To define Setup variables

Click to open the Setup Variables folder.

    • To create user-defined variables:
Type the names and values in the fields provided. Additional fields appear as you specify values.

    • To assign values to supplied variables:

  1   Type their names and values in the System Variables window or click System Variables and a dialog box appears.

  2   Select the desired Variable Type and a list of variables of that type appears.

  3   Select the variable. A description is displayed.

  4   Enter the desired value for that variable and click Apply.

  5   Continue defining variables in this manner, clicking Apply to effect each change. When you are through defining variables, click OK.

Creating User-defined Variables

To create user-defined variables:

  1   Select Tools > System Variables in the Main window if you are creating global variables, otherwise click to open the Model, DUT, or Setup Variables folder, as desired.

  2   In the System Variables window that appears, type the names and values in the fields provided. Additional fields appear as you specify values.
