[Ngspice-users] NG-Spice and WIN32

[Holger V. <hol...@un...>]

Dear all,

I have successfully compiled NG-Spice-Rework 13 for WIN32 using CYGWIN.

This is the procedure:

Install CYGWIN from http://sources.redhat.com/cygwin/
Install Xfree XServer and X11 support for WIN32 from
http://xfree86.cygwin.com/

Download ng-spice-rework-13 and expand into a directory 
G:\ng-spice-rework-13.

Open CYGWIN console box.

cd /cygdrive/g/ng-spice-rework-13  (CYGWIN notation)

edit configure.in
old:
AC_CHECK_LIB(Xext, XShmAttach,X_LIBS="$X_LIBS
-lXext",AC_MSG_ERROR(Couldn't find Xext librairies), $X_LIBS $X_EXTRA_LIBS)
new:
AC_CHECK_LIB(Xext,main,X_LIBS="$X_LIBS -lXext",AC_MSG_ERROR(Couldn't
find Xext librairies), $X_LIBS $X_EXTRA_LIBS)

autoconf
./configure


edit ngspice.h
line 102
// added for CYGWIN
#ifndef HUGE
#define HUGE HUGE_VAL
#endif

edit test_cx_ph.c
line 11
// added for CYGWIN
#include "defines.h"

edit outitf.c
line 31
// added for CYGWIN
#include <float.h>


to get rid of linking errors with x libraries:
edit makefile in /src
line 128
old:
#LIBS = -lm -lncurses   -L/usr/X11R6/lib -lX11 -lXt -lXext -lXaw -lXmu
-lSM -lICE
new:
LIBS = -lm -lncurses -liberty  -L/usr/X11R6/lib -lXaw -lXt -lXmu -lXext
-lX11 -lXpm -lSM -lICE
line 142
old:
#X_LIBS =  -L/usr/X11R6/lib -lX11 -lXt -lXext -lXaw -lXmu
new:
X_LIBS =  -L/usr/X11R6/lib -lXaw -lXt -lXmu -lXext -lX11 -lXpm

missing link to asprintf in -liberty

(this might better be changed in configure.in, I guess)

remaining link errors:
RESLoad
get_...

change to makefile in line 92

# ngspice_LDADD =  	spice.o 	frontend/libfte.a

Now a double definition errors of function
StrongInversionNoiseEval(vgs, vds, model, here, freq, temp) is removed
by creating
StrongInversionNoiseEvalV1(vgs, vds, model, here, freq, temp) and
StrongInversionNoiseEvalV2(vgs, vds, model, here, freq, temp)
in b3v1noi.c and b3v2noi.c, line 47, 256 and 271 respectively

'make' now creates all binaries.

Then I have put all binaries in a G:\ng-spice-rework-13\bin directory,
also created  /help, /man and /scripts directories.

After starting the XServer,
NG-Spice may be run by by the following batch script:

REM*************************************************************************
set
PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;G:\ng-spice-rework-13\bin;C:\cygwin\bin;C:\cygwin\usr\x11r6\bin

SET SPICE_NO_DATASEG_CHECK=TRUE
SET SPICE_HELP_DIR=../help
SET MANPATH=../man
SET SPICE_SCRIPTS=../scripts

cd G:

cd G:\ng-spice-rework-13\bin

run ./rxvt -sb -e ./ngspice.exe

REM ngspice.exe ../examples/adder.cir -b -r ../examples/adder_ng.out -o 
../examples/adder_ng.log

REM ngspice.exe ../Exam_BSIM3/adder_mos.cir -b -r 
../Exam_BSIM3/adder_mos.out -o ../Exam_BSIM3/adder_mos.log

run c:/cygwin/usr/x11r6/bin/xman.exe

REM****************************************************************


Using rxvt, ngspice will open up in the rxvt-window on the X screen. The 
two line commented out with REM will start the batch mode (here in a DOS 
box).

Things are by far not perfect, e.g. reaction to keyboard entries is
strange on non alphanumeric keys (I need SHIFT BACKSPACE for doing 
BACKSPACE ...), the -o log file in batch mode does not show CPU time and 
memory used.

But NG-Spice runs and simulates examples
(e.g. adder.cir from UCB or adder_mos.cir with BSIM3v3.2, which I 
derived fron adder.cir). Plotting is done via X on top of Windows. So 
this seems to be a nice start for ngspice on WIN32.
