where parameters in slanted typewriter font are optional.
InitialCondition
With InitialCondition −> ic, you can specify initial currents and voltages for inductors and
capacitors, respectively. If no initial condition is given explicitly, it will be assumed to be zero (AC
analysis) or will be calculated automatically from operating-point data (transient analysis).
Pattern
The option Pattern allows you to select the matrix fill-in patterns for two-terminal admittances and
impedances (immittances) to be used in modified nodal analysis (MNA). By default, all impedances Z
are converted to equivalent admittances Y ⩵ Z to keep the dimensions of the circuit equations
small. The following values are allowed:
Automatic
Admittance
Impedance
convert impedances to admittances for MNA
use admittance pattern for immittances
use impedance pattern for immittances
Values for the Pattern option.
An explicit Pattern specification overrides the setting of the option ConvertImmittances
locally.
Symbolic
With Symbolic −> symbol, you can specify an alternative symbolic element value in addition to a
numerical value given by Value −> value. This feature is used to associate design-point data with
symbolic element values. Note that symbol is not strictly required to be a symbol; you may also
specify any Mathematica expression. However, design-point management will work as intended only
if the value of the Symbolic option is a symbol.
