H. Vogt, Jan 12th, 2014
ngspice-26 has been compiled from the ngspice-26 tarball, Jan 11th, 2014.
ngspice.exe was generated by MS Visual Studio 2008, configuration
ReleaseOMP, using full optimization (compiler flags /O2 /Oi /Ot /GL, linker flag /ltcg).
vcomp90.dll is the microsoft runtime distributable for OpenMP
(see C:\Program Files (x86)\Microsoft Visual Studio 9.0\1031\redist.txt).
The XSPICE code models *.cm were generated with
TDM mingw gcc 4.8.1 and MSYS 1.0.10 using the following configuration:
./configure --with-windows --enable-xspice --enable-cider --disable-debug
gcc is invoked with the -O2 compiler flag, which is set in configure.ac.
This version of ngspice 26 thus does not contain the adms or ndev extensions.
Expand the ngspice-26-140112.zip file directly into C: so that you will get C:\Spice\bin etc.
For other places for ngspice installation, see below.
The following examples are tested under Windows XP professional and Windows 7 64 Bit.
Directory /examples offers some example input files for special commands.
*** How to use ngspice with examples provided in directory /tests ***
*********************************************************************
Starting ngspice from MS Explorer window (interactive mode):
Double click on ngspice.exe in C:\Spice\bin
*** ngspice window:
cd c:\spice\tests\bsim4
source comprt.cir
run
display
plot v(1) v(2) v(3) v(8) v(9)
write comprt2.raw
quit
*********************************************************************
*********************************************************************
* Starting ngspice within the msys window, interactive mode:
* Open an MSYS window.
*** msys window:
export PATH=$PATH:/c/Spice/bin
cd /c/Spice/tests/bsim4
ngspice comprt.cir
*** ngspice window:
run
display
plot all
*** write data into raw file to actual directory /c/Spice/tests/bsim4:
write comprt.raw
quit
If you want to use interactive mode with a circuit file in a different
directory (e.g. C:\test\comprt.cir) , you have to call ngspice like this:
ngspice C:\\test\\comprt.cir
or
ngspice C:\\test/comprt.cir
MSYS 1.0.10 is specific about file and directory names!
You cannot start ngspice from C:\ or D:\ directly if you don't
have administrator rights. You may choose a subdirectory instead.
*********************************************************************
*********************************************************************
* Starting ngspice within the msys window, batch mode:
* Open an MSYS window.
*** msys window:
export PATH=$PATH:/c/Spice/bin
cd /c/Spice/tests/bsim4
ngspice -b -r comprt3.raw -o comprt3.out comprt.cir
* Plotting
*** msys window:
ngspice
load comprt3.raw
plot v(1) v(2) v(3) v(8) v(9)
quit
* The data in the raw file comprt3.raw are stored in a compact binary
* format. If you want them to be ASCII, you have to uncomment line
set filetype=ascii
* in C:\Spice\share\ngspice\scripts\spinit (remove the '*').
*********************************************************************
*********************************************************************
* Starting ngspice within the dos window (cmd.exe) , interactive mode:
* (also an example for using xspice extension)
* Open a DOS window.
*** DOS window:
set PATH=%PATH%;C:\Spice\bin
cd C:\Spice\examples\transimpedanceamp
ngspice output.net
*** ngspice window:
run
display
* end display with 'q'
plot vout2
* write all data into raw file to actual directory C:\Spice\tests\transimpedanceamp:
write timp.raw
* write only input and output
write timp2.raw v3#branch vout2
quit
Calling a source file in a different directory is done by:
ngspice D:\testinput\output.net
*********************************************************************
*********************************************************************
* Use ngnutmeg for plotting within the dos window (cmd.exe), using the
raw file timp.raw created above:
* Open a DOS window.
*** DOS window:
set PATH=%PATH%;C:\Spice\bin
cd C:\Spice\examples\transimpedanceamp
ngspice
*** ngspice window:
load timp.raw
plot vout2
plot i(v3)
quit
*********************************************************************
*********************************************************************
* Starting ngspice within the dos window (cmd.exe) , batch mode, using
* .plot and/or .print commands in the input file (printer plot output),
* no raw file, similar to SPICE2G6:
* Open a DOS window.
*** DOS window:
set PATH=%PATH%;C:\Spice\bin
cd C:\Spice\examples\
ngspice -b -o cs.out cs_mixtv4.inp
* The ouput will be plotted and printed to C:\Spice\examples\cs.out.
* If you enter
ngspice -b -r cs.raw -o cs.out cs_mixtv4.inp
* instead, you will get a raw file (simulator output data),
* .print and .plot will be ignored.
* You may plot the data by using ngnutmeg (see example above).
*********************************************************************
*********************************************************************
* A numparam example with convergence and ringing problems
(Xiaoqun Wu e.a.: "Bifurcation Behavior of SPICE Simulations of Switching Converters: A Systematic
Analysis of Erroneous Results", IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 22, NO. 5, SEPTEMBER 2007, p.1743
dos window (cmd.exe) , interactive mode:
* Open a DOS window.
*** DOS window:
set PATH=%PATH%;C:\Spice\bin
cd C:\Spice\examples\numparam
ngspice power.cir
*** ngspice window:
run
plot vc#branch
*** compare to literature by selecting appropriate plot windows using right mouse tab
* write all data into raw file to actual directory C:\Spice\examples\numparam:
write power-all.raw
* write only relevant output
write power.raw vc#branch
quit
*********************************************************************
*********************************************************************
* Running ngspice from a different directory (for example D:\tmp)
* Starting ngspice within the dos window (cmd.exe) , interactive mode:
* Extract ngspice.zip to D:\tmp
* Edit spinit (found in D:\tmp\Spice\share\ngspice\scripts) to have the correct
path for the XSPICE codemodels:
Line
codemodel C:/Spice/lib/spice/spice2poly.cm
has to be replaced by
codemodel D:/temp/Spice/lib/spice/spice2poly.cm
the other codemodels lines have to be changed respectively.
* Open a DOS window.
*** DOS window:
set SPICE_LIB_DIR=D:\tmp\Spice\share\ngspice
set PATH=%PATH%;D:\tmp\Spice\bin
cd D:\tmp\Spice\examples\transimpedanceamp
D:
ngspice output.net
*** ngspice window:
run
plot vout2
* write all data into raw file to actual directory D:\tmp\Spice\tests\transimpedanceamp:
write timp.raw
* write only input and output
write timp2.raw v3#branch vout2
quit
*********************************************************************
*********************************************************************
* Running ngspice from a different directory (for example D:\tmp)
* Starting ngspice within the dos window (cmd.exe) , interactive mode
or starting with double click on ngspice in MS explorer:
* Extract ngspice.zip to D:\tmp
* under Windows XP you may put the following lines into C:\autoexec.bat:
set SPICE_LIB_DIR=D:\tmp\Spice\share\ngspice
set PATH=%PATH%;D:\tmp\Spice\bin
* Edit spinit (found in D:\tmp\share\ngspice\scripts) to have the correct
path for the XSPICE codemodels:
Line
codemodel C:/Spice/lib/spice/spice2poly.cm
has to be replaced by
codemodel D:/temp/Spice/lib/spice/spice2poly.cm
the other codemodels lines have to be changed respectively.
* You may then start immediately after opening the command window (cmd.exe)
with:
cd D:\tmp\Spice\examples\transimpedanceamp
D:
ngspice output.net
*** ngspice window:
run
plot vout2
* write all data into raw file to actual directory D:\tmp\Spice\tests\transimpedanceamp:
write timp.raw
* write only input and output
write timp2.raw v3#branch vout2
quit
*********************************************************************
*********************************************************************
*********************************************************************
* spinit
* spinit is used to set options or to set varioables. spinit is read into ngspice
before any input file. The codemeodel path for xspice may be set as well.
There is a search sequence for spinit.
1) If the invironmental variable is SPICE_LIB_DIR is set to a path, e.g. to
SPICE_LIB_DIR=D:\tmp\Spice\share\ngspice, then spinit is searched for
in D:\tmp\Spice\share\ngspice\scripts. If not set then we look for it in
C:\Spice\share\ngspice\scripts. If this path is not available or spinit is
not there, then ngspice searches for spinit in the path where ngspice.exe
resides. If not found there, a warning note is issued.
* .spiceinit
* .spiceinit is read directly after the spinit file. You may keep spinit as is,
and put any personal preset variables or scripts into .spiceinit. Data in
.spiceinit will override data from spinit.
ngspice will search for .spiceinit either in your home directory or in the
directory where ngspice.exe is located.
*********************************************************************
*********************************************************************
* Universial, simple install
Put ngspice.exe and spinit into a subdirectory myspice\bin
Put the codemodels (e.g. analog.cm) into a subdirectoty myspice\codemodels.
Edit spinit and change the codemodel lines to
codemodel ../codemodels/spice2poly.cm
etc.
Instead of 'myspice' you may now choose any directory for your installation
of \bin and \codemodels, even C:\ will work.
