% man commands fault .

\section{{\tt FAULT} command}
\index{fault command}
\index{change values: temporary}
%------------------------------------------------------------------------
\subsection{Syntax}
\begin{verse}
{\tt FAult} {\it partlabel}={\it value} ...
\end{verse}
%------------------------------------------------------------------------
\subsection{Purpose}
Temporarily change a component value.
%------------------------------------------------------------------------
\subsection{Comments}
This command quickly changes the value of a component, usually with the
intention that you will not want to save it.
If you apply this command to a nonlinear or otherwise strange part, it becomes
ordinary and linear until the fault is removed.
It is an error to {\tt fault} a model call.
If several components have the same label, the fault value applies to all of
them. (They will all have the same value.)
The {\tt unfault} command restores the old values.
%------------------------------------------------------------------------
\subsection{Example}
\begin{description}
\item[{\tt fault R66=1k}] R66 now has a value of 1k, regardless of what it
was before.
\item[{\tt fault C12=220p L1=1u}] C12 is 220 pf and L1 is 1 uH, for now.
\item[{\tt unfault}] Clears all faults. It is back to what it was before.
\end{description}
