All accept either Spice compatible order dependent parameters, or easier keyword=value notation.

The syntax is identical for all supported components.

Nonlinear transfer functions use time as the independent variable. Some may not make sense, but they are there anyway.

Nonlinear transfer functions are charge or flux as a function of input (voltage or current). Charge and flux are conserved, and can be probed.

Nonlinear transfer functions are current or voltage as a function of input (voltage or current). Resistors define voltage as a function of current. Conductances define current as a function of voltage.

Nonlinear transfer functions are output (voltage or current) as a function of input (voltage or current).

`COMPLEX`- Complex (re, im) value.

`Bandwidth`=*x*-
AC analysis bandwidth. (Default = infinity.) The transfer function
is frequency dependent, with a 3 DB point at this frequency. There is
frequency dependent phase shift ranging from 0 degrees at low
frequencies to 90 degrees at high frequencies. The phase shift is 45
degrees at the specified frequency. AC ANALYSIS ONLY.

`Delay`=*x*-
AC analysis delay. (Default = 0.) The signal is delayed by x seconds,
effectively by a frequency dependent phase shift. AC ANALYSIS ONLY.

`Phase`=*x*-
AC analysis phase. (Default = 0.) A fixed phase shift is applied.
This is primarily intended for sources, but applies to all elements.
AC ANALYSIS ONLY.

`IOffset`=*x*-
Input offset. (Default = 0.) A DC offset is added to the “input”
of the element, before evaluating the function.

`OOffset`=*x*-
Output offset. (Default = 0.) A DC offset is added to the “output”
of the element, after evaluating the function.

`Scale`=*x*-
Transfer function scale factor. (Default = 1.) The transfer function
is multiplied by a constant.

`TNOM`=*x*-
Nominal temperature. (Default = .option TNOM) The nominal values
apply at this temperature.

`TEMP`=*x*-
Actual temperature. (Default = current global simulation temperature)
This is the actual device temperature.

`DTEMP`=*x*-
Temperature rise over ambient. (Default = 0.) The actual device
temperature is the global simulation temperature plus
`dtemp`.

`TC1`=*x*-
First order temperature coefficient. (Default = 0.)

`TC2`=*x*-
Second order temperature coefficient. (Default = 0.)

`IC`=*x*- Initial condition. An initial value, to force at time=0. The actual parameter applied depends on the component. (Capacitor voltage, inductor current. All others ignore it.) You must use the “UIC” option for it to be used.
