Inductor: This device is translated as an inductor.

Example SPICE Command Line:

{{l1 1 2 1pH IC=15mA

SPICE dialect and netlist syntax

Spice2/3:

l id n1 n2 value [ ic= icamp ]

PSpice:

l id n1 n2 value [ ic= icamp ]

HSpice:

l id n1 n2 [ l= value ] [[ tc1= ] tc1 [[ tc2= ] tc2 ]] [ scale= scale ]

ADS Netlist Syntax:

L:l id n1 n2 L= value

ADS Schematic Symbol:

Instance Parameters:

lid = Inductor element name
n1 = Positive node
n2 = Negative node
value = The inductance in Henries
ic = The initial (time-zero) value of inductor current (in Amps)
tc1 = First order temperature coefficient
tc2 = Second order temperature coefficient
scale = Element scale factor. Default=1.0.
mult = Multiplier used to simulate multiple parallel devices. Default=1.0
dtemp = Element and circuit temperature difference. Default=0.0
R = Resistance in ohms of the inductor element.
equation = The inductor value can be described as a function of any node voltages, branch currents, and any independent variables such as TIME, frequency (HERTZ), or temperature (TEMPER). The type of variable L depends upon is indicated by the parameter "LTYPE". Most commonly L depends upon I(Lxxx), which is assumed with the default of LTYPE=0 as explained below.
LTYPE = If inductance L is a function of I(Lxxx), set LTYPE to 0. Otherwise, set LTYPE to 1. The inductance flux is calculated differently depending on the value of LTYPE. LTYPE must be set properly to provide correct simulation results. Defining L as a function of multiple variables is not recommended. Default=0.
poly() = Polynomial function

Comments:

If SCALE is specified, Value=Value*scale

Unsupported Syntax and Parameters

PSpice:

PSpice Inductor model is supported by ADS but not translated yet.
lid n1 n2 [mname] value

HSpice:

Nonlinear inductor lid n1 n2 poly l0 l1 l2...
This is supported by ADS as a component called NonlinL.

The ADS Netlist Syntax should be:

NonlinL:lid n1 n2 coef=list(l0 l1 l2...) [ic=ic]
lid n1 n2 L=`equation' ltype=[0|1] [R=val]

This syntax requires a Symbolically Defined Device (SDD) in ADS if ltype=0. This is not currently handled by the translator. Please contact customer support for assistance in writing the SDD to represent the current through the inductor.
