The C model provides the partial derivation of two input signals DERIV=δY/δX with the active
values of the input signals at each simulation step. Within the dialog you can define the X
range of values and a initial delay.

Dialog Settings
«Input Signal»
Enter a quantity name used in your model sheet in the text box to define the input signal
(RLOAD.I, STEP.VAL, STATE.ST, VAR) or use the pin to connect a quantity. Please note: You
cannot use conservative nodes from circuits as input signal (N0002, GND).
� � «Use Pin»
If the box is checked, the input signal is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
«Delay [s]»
Defines the initial delay of the sensitivity function. Enter a numerical value, a variable, or an
expression in the text box to define the initial delay at simulation start.
«X Interval Lower Limit»«X Interval Upper Limit»
Common parameter type. Enter a numerical value, a variable, or an expression in the text box.
