Requirements for Characteristic Blocks
• a physically useful characteristic for each parameter value (for voltage '0' is also current
'0', otherwise errors occur during simulation)
• the same sequence of monotonously increased or decreased values for the X axis
• a constant select parameter value (Y axis) for each block
• across all blocks the select parameter must be monotonously increased or decreased.

Open the property dialog of a nonlinear component, for example of a resistor. Select «Nonlinear»
in the dialog and click . Enter the name of the 3D Lookup Table component
in the text box (Name.VAL, for example Werte3D501.VAL). You cannot use the pin
function with the 3D Lookup Table.
During simulation, the current values of the nonlinear component are available for X,Y, and Z
value in the 3D Lookup Table component. If you define outputs, you can display these quantities.
Components Using Characteristics
The table shows SIMPLORER’s interpretation of the corresponding values of nonlinear components.
The X, Y, and Z axis are interpreted as follows:

«Parameter Variable»
The variable value selects one of the defined characteristic blocks. Enter a variable name in
the text box. The range of the values must be available in the characteristic file; otherwise,
incorrect values are used.
