Parameters (definable at component level)
The following component-level parameters are definable for this model type and are listed on the Parameters tab of the Sim Model dialog. To access this dialog, simply double-click on the entry for the simulation model link in the Models region of the Component Properties dialog.
| Value | value for the resistance (in Ohms). |
| Set Position | the position of the wiper along the resistors' track. The value can be in the range 0 (fully left/anti-clockwise) to 1 (fully right/clockwise), with 0.5 being the halfway point (i.e. the resistors' value will be half that specified in the Value field). |
Examples
Consider the variable resistor in the image above, with the following characteristics:
- Pin1 is connected to net
Input - Pin2 is connected to net
Inv - Designator is
R1 - Value =
1K - Set Position =
0.5
The entry in the SPICE netlist would be:
