.ds ngspice \s-2NGSPICE\s+2
.SH "NAME"
ngspice \- circuit simulator derived from \*[spice]\&3f5
.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 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.)

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
