NAME

       gnucap - GNU Circuit Analysis Package

SYNOPSIS

       gnucap [-b filename] [-i filename] [filename]

DESCRIPTION

       Gnucap  is  a  general  purpose circuit simulator.  It performs nonlinear dc and transient
       analyses, fourier analysis, and ac analysis linearized at an operating point.  It is fully
       interactive  and  command  driven.   It can also be run in batch mode or as a server.  The
       output is produced as it simulates.  Spice compatible models for the MOSFET (level  1,2,3)
       and diode are included in this release.

       Since  it  is  fully  interactive, it is possible to make changes and re-simulate quickly.
       The interactive design makes it well suited to the typical iterative design  process  used
       it  optimizing  a  circuit design.  It is also well suited to undergraduate teaching where
       Spice in batch mode can be quite intimidating.  This version, while  still  officially  in
       beta  test,  should  be  stable enough for basic undergraduate teaching and courses in MOS
       design, but not for bipolar design.

       In batch mode it is mostly Spice compatible, so it is often possible to use the same  file
       for both Gnucap and Spice.

       The  analog  simulation  is based on traditional nodal analysis with iteration by Newton's
       method and LU decomposition.  An event queue and incremental matrix update  speed  up  the
       solution for large circuits (at some expense for small circuits).

       It  also  has  digital  devices  for  mixed signal simulation.  The digital devices may be
       implemented as either analog subcircuits or as true digital models.   The  simulator  will
       automatically  determine  which  to  use.   Networks  of  digital devices are simulated as
       digital, with no conversions to analog between gates.  This results  in  digital  circuits
       being  simulated  faster  than on a typical analog simulator, even with behavioral models.
       The digital mode is experimental and needs work.  There will be  substantial  improvements
       in future releases.

OPTIONS

       Two  command-line  options  are  available.  Only  one  of  these  may be specified. If no
       parameters are given, gnucap will start in interactive mode.

       -b filename
              execute the commands in the named file then exit (batch mode)

       -i filename
              execute the commands in the named file then go into interactive mode

BUGS

       See /usr/share/doc/gnucap/bugs for a list of known bugs in this release.

       Gnucap is an ongoing research project.  It is being released in  a  preliminary  phase  in
       hopes  that  it  will  be useful and that others will use it as a thrust or base for their
       research.  I also hope for some comments that may help me direct my research.
