Defining Model Parameters

The Model Parameters folder displays the current parameter values. These parameters are common to all DUTs for that model and are used in a simulation. When a new model is read, these values are set to the defaults defined in the circuit. The values change after extractions and optimization are performed.

To define the model parameters, select Model Parameters.

The Parameters table contains the same names as those specified in the MODEL definition of the Circuit. However, by editing the table, the values can be set independently of those in the circuit definition and can be specified as a real number or an equation. In addition, you can set limits by entering minimum and maximum values for each parameter. Parameter values that are outside their limits are clamped to their minimum or maximum values.

After editing the defaults, you can store the current set of parameter values in a temporary buffer (Memory Store All) and recall these values at any time during the IC-CAP session (Memory Recall All). If you prefer, you can restore the default values (Reset All).
