SYNOPSISngspice [options] [file ...]
DESCRIPTIONThis 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.
- -n or --no-spiceinit
- 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.
- -q or --completion
- Enable command completion. (defect)
- -t term or --term=term
- The program is being run on a terminal with mfb name term.
- -b or --batch
- 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.
- -s or --server
- 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.
- -i or --interactive
- 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.
- -r rawfile or --rawfile=file
- Use rawfile as the default file into which the results of the simulation are saved.
- -c circuitfile or --circuitfile=circuitfile
- Use circuitfile as the default input deck.
- -h or --help
- Display a verbose help on the arguments available to the program.
- -v or --version
- Display a version number and copyright information of the program.
- -a or --autorun
- -o outfile or --output=outfile
- All logs generated during a batch run (-b) will be saved in outfile.
- -p or --pipe
- 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.
Further arguments are taken to be SPICE input decks, which are read and saved. (If batch mode is requested then they are run immediately.)
- SPICE_ASCIIRAWFILE default 0
- Format of the rawfile. 0 for binary, and 1 for ascii.
- SPICE_NEWS default $SPICE_LIB_DIR/news
- A file which is copied verbatim to stdout when ngspice starts in interactive mode.
- SPICE_MFBCAP default $SPICE_LIB_DIR/mfbcap
- SPICE_HELP_DIR default $SPICE_LIB_DIR/helpdir
- SPICE_SCRIPTS default $SPICE_LIB_DIR/scripts
- In this directory the spinit file will be searched.
- SPICE_PATH default $SPICE_EXEC_DIR/ngspice
various undocumented ngspice centric environment variables :
Common environment variables :
- TERM LINES COLS DISPLAY HOME PATH EDITOR SHELL
- The System's Initialisation File.
- .spiceinit or $HOME/.spiceinit
