.TH NGSPICE 1 "6 June 2010"
.ds = \-\^\-
.ds ngspice \s-2NGSPICE\s+2
.SH "NAME"
ngspice \- circuit simulator derived from SPICE3f5
.SH "SYNOPSIS"
\fBngspice\fP [\fIoptions\fP] [\fIfile\fP ...]
.SH "DESCRIPTION"
This man page is just a small overview.
The primary documentation of ngspice is in the ngspice User's Manual,
which is available as a pdf file.
.SH "OPTIONS"
.TP
\fB\-n\fP or \fB\*=no\-spiceinit\fP
Don't try to source the file ".spiceinit" upon startup. Normally ngspice
tries to find the file in the current directory, and if it is not found then
in the user's home directory.
.TP
\fB\-q\fP or \fB\*=completion\fP
Enable command completion. (defect)
.TP
\fB\-t\fP \fIterm\fP or \fB\*=term=\fP\fIterm\fP
The program is being run on a terminal with \fBmfb\fP name \fIterm\fP.
.TP
\fB\-b\fP or \fB\*=batch\fP
Run in batch mode.
ngspice will read the standard input or the specified
input file and do the simulation.
Note that if the standard input is not a terminal, ngspice will default
to batch mode, unless the \-i flag is given.
.TP
\fB\-s\fP or \fB\*=server\fP
Run in server mode.
This is like batch mode, except that a temporary rawfile is used and then
written to the standard output, preceded by a line with a single "@", after
the simulation is done.
This mode is used by the ngspice daemon.
.TP
\fB\-i\fP or \fB\*=interactive\fP
Run in interactive mode.
This is useful if the standard input is not a terminal but interactive mode
is desired.
Command completion is not available unless the standard input is a terminal,
however.
.TP
\fB\-r\fP \fIrawfile\fP or \fB\*=rawfile=\fP\fIfile\fP
Use \fIrawfile\fP as the default file into which the results of
the simulation are saved.
.TP
\fB\-c\fP \fIcircuitfile\fP or \fB\*=circuitfile=\fP\fIcircuitfile\fP
Use \fIcircuitfile\fP as the default input deck.
.TP
\fB\-h\fP or \fB\*=help\fP
Display a verbose help on the arguments available to the program.
.TP
\fB\-v\fP or \fB\*=version\fP
Display a version number and copyright information of the program.
.TP
\fB\-a\fP or \fB\*=autorun\fP
FIXME
.TP
\fB\-o\fP \fIoutfile\fP or \fB\*=output=\fP\fIoutfile\fP
All logs generated during a batch run (\fB\-b\fP) will be saved in \fIoutfile\fP.
.TP
\fB\-p\fP or \fB\*=pipe\fP
Allow a program (e.g., xcircuit) to act as a GUI frontend for
ngspice through a pipe.
Thus ngspice will assume that the pipe is a tty and allows one to run in
interactive mode.
.PP
Further arguments are taken to be SPICE input decks, which are read
and saved.
(If batch mode is requested then they are run immediately.)
.SH "ENVIRONMENT"

\fBSPICE_EDITOR\fP
.TP
\fBSPICE_ASCIIRAWFILE\fP default \fI0\fP
Format of the rawfile.
\fI0\fP for binary, and \fI1\fP for ascii.
.TP
\fBSPICE_NEWS\fP default \fI$SPICE_LIB_DIR/news\fP
A file which is copied verbatim to stdout when ngspice starts in interactive mode.
.TP
\fBSPICE_MFBCAP\fP default \fI$SPICE_LIB_DIR/mfbcap\fP
