Spice3f4
---------- New features in Spice3f.4
With this release, the University of California will no longer
be providing technical support for Spice3, and no plans have been made
for providing support any time in the future. Some work on Spice3 will
continue (notably the BSIM-3 model and perhaps other device models).
The following is a list of new features and fixes from the previous
release of Spice3, 3f.3 (note that 3f.4 is a "last minute" release with
only a few new changes):
Initial conditions specified across voltage sources is now handled
"alter" command accepts expressions, new syntax is either:
alter dev param = expr
alter @dev[param] = expr
"altermod" command for altering model parameters (was "alter")
minor bug fixes
The following is a list of new features and fixes from the previous
major release of Spice3 (3f.2) and the previous release (3f.3) (note
that 3f.3 is primarily a bug-fix release over 3f.2):
Added non-linear controlled source functions "u(x)" and "uramp(x)"
Fixes to AC sensitivity calculation
Fixes to initial conditions code
Fixed spurious error messages when running multiple anaylses in
batch mode
Fixed plotting (again)
Fixed "available memory" calculation
Fixed default scale to be log for analysis done by decade/octave
(ac, disto, noise); use plot option "linear" to override
Fixed asciiplot
Fixed problem causing BSIM models to not be found
Removed "spiced" (a remote-spice daemon for BSD unix); added an
rspice command which uses "rsh" instead.
Online help info is now identicle to the "Spice3f User's Manual"
Fixed numerous and various parsing errors
"TF" analysis output is now identified as "TF" data, not "DC" data
Complex numbers and Real vectors are now printed by the
"show"/"showmod" commands
Fixes to help MacIntosh port
Port for DEC Alpha running OSF/1
Misc. changes to improve portability
Additional features since release 3e.2 are:
AC and DC Sensitivity.
MOS3 discontinuity fix ("kappa").
Added a new JFET fitting parameter.
Minor initial conditions fix.
Rewritten or fixed "show" and "trace" commands.
New interactive commands "showmod" and "alter".
Minor bug-fixes to the Pole-Zero analysis.
Miscellaneous bug fixes in the front end.
---------- Systems supported
Spice3f.4 has been compiled and and run under the following operating systems:
OSF 1, DEC Alpha
Ultrix 4, RISC or VAX
SunOS 4, Sun3 or Sun4
The following systems have been successfully tested either in the past or
by someone outside of UC Berkeley.
MS-DOS on the IBM PC, using MicroSoft C 5.1 or later
AIX V3, RS/6000
HP-UX 8.0, 9000/700
Dynix 3.0, Sequent Symmetry or Balance (does _not_ take advantage of
parallelism)
HP-UX 7.0, 9000/300
Irix 3.2, SGI Personal Iris
NeXT 2.0
Apple MacIntosh, Using Think C
Other systems may require a small amount of porting effort. Note that
the 'gcc' C compiler was used successfully to compile Spice3f.4.
Due to the heavy use of floating point math operations, Spice3 on the
PC requires a math co-processor. Also, on the PC, SVGA displays are
_not_ supported. Only CGA, EGA, and VGA displays are supported (via
the MicroSoft graphics library) at this time.
A 68020 or better processor and a math co-processor is required for
the MacIntosh.
Systems using the X11 Window System (generally any "workstation" class
of system) must have the MIT Athena Widget Set available ("libXaw.a"
and possiblely "libXmu.a"). These are frequently not distributed or
distributed as "usupported software" by commercial workstation
vendors.
---------- Unloading Spice3 from disk or tape
The Unix distribution comes on 1/2" 9-track tape, 8mm tape, or DEC TK50 tape
in "tar" format. The MS-DOS distribution comes on several 3.5" floppy
diskettes (both high and low density) in the standard MS-DOS format.
The contents of both distributions are identical, including filenames,
except for the additional files on the MS-DOS disks used for automatic
unloading.
The source code and associated data files for spice3f.4 require over 6MB,
and up to an additional 22MB may be required to compile under Unix (for a
DEC RISC workstation with the compiler option '-g'). For MS-DOS using
MicroSoft C 5.1 or later, nearly 8MB (beyond the 6MB for the source) is
required.
UNIX: The UNIX distribution of Spice3f.4 comes in "tar" format. To
extract Spice3f.4 first create the directory that you wish to
hold the distribution and "cd" into that directory. Then
execute the command "tar x" (after mounting the tape). Note
that some sites may require that you explicitly indicate the
tape drive name when using the "tar" command; this is done with
the 'f' flag, for example "tar xf /dev/rmt0h".
MS-DOS: Spice3f.4 comes on MS-DOS format 3.5" disks. To extract the
distribution onto a hard disk, create the directory on the hard
disk that you wish to hold the source code. "cd" into that
directory on the hard disk. For each of the distributed disks,
IN ORDER, insert the disk into the drive (we'll assume drive
"B:" here), and enter "B:UNLOAD B:". This will use the script
"unload.bat" to extract the source files off of the disk and
into the current directory or a subdirectory of the current
directory. You might see the error "File not found ????????.???",
that is normal.
Converting the MS-DOS format disks to UNIX: The MS-DOS format is not
directly readable by UNIX systems. One publically available
tool for doing this is known as "mtools" (search popular
ftp sites), but this is not the only method. Note: In MS-DOS,
text file lines end with "^M^J", where under UNIX lines end only
with "^J". Also, execute permission needs to be set on all
files in the "util/" subdirectory when moving to UNIX.
MAC: Spice3 is not distributed in a format for the Apple MacIntosh. You
must determine how to transfer the files to a Mac from the media that
you have.
---------- Compiling Spice3f.4 under UNIX
To build Spice3f.4 on a Unix system follow the steps below.
For additional notes on internal changes and porting issues,
please inspect the subdirectory "notes".
First you must edit the file "conf/defaults" and change the
listed parameters to reflect the standard organization of
software at your site. A description of each parameter is
included in this file.
Second, for each type of system at your site, you must provide
a file in the same subdirectory ("conf/") which contains
exceptions to the previously edited "defaults" file; note that
even if you are supporting one type of system with no
exceptions this is still necessary. Several files are supplied for
the system types that have been tested with this distribution,
including "mips" (for DECstations), "sun4", "sequent", "irix",
"hpux", and "rs6000".
Note that some of these per-system definition files have
special definitions which are required for the given system and
which do not appear in the "defaults" file.
Note also that successful compiling does not depend on the
particular names given to these 'exception' or 'system
definition' files. For example, the "mips" configuration file
could have been named "decstation"; this name is used for
generating unique directory names such that different systems
to not use the same area for the compile process (more detail
are listed in the "defaults" file).
Finally, it is possible to combine additional files
After the defaults file has been edited and a system-dependent
file created or modified, run the command "util/build system"
from the directory above the "util" subdirectory; for "system"
you must substitute the name of the system-dependent file that
you created or modified in the previous step. Spice3 will then
be built via recursive "make" commands (it may take a several
seconds to get going on some systems). The total time can be
as little as 20 minutes or as long as four hours depending on
the speed and load of your system. Compiling across NFS will
slow down compiling significantly.
If you have trouble using the "build" script, try "build -help"
for infomation on debugging options. Some system combinations
may require listing more than one system name on the "build" line,
for example "build hpux hp300" to build on an HP 9000/300 as
opposed to a HP 9000/700. When the build script has successfully
completed, see the section below on Installing Spice3.
---------- Additional Notes on Compiling Spice3f.4 under UNIX
NOTE: Some systems have a problem with directory names containing
a "-" in either the full source directory name or the full directory
name of any program used in compiling. This may show up as an
unexpected or unreasonable error message. Avoid directory names
with a "-" (this is an old bug in the "make" command, which has
propagated to many vendors before being fixed).
NOTE: On some systems, the "build" scripts seems sluggish. This
may be caused by a long "$PATH", with many entries before "/bin"
and "/usr/bin"; you may be able to speed up the script by trimming
your "$PATH" before running the build script.
NOTE (SunOS): There is small bug somewhere in one version of the
Sun-supplied X11 libraries. This bug results in the following
routines being undefined in the "link" stage:
_get_wmShellWidgetClass
_get_applicationShellWidgetClass
This is apparently a problem with the dynamic-link version of the
"Xmu" library. If you have this problem, the best reported fix is
to use the following options on the "link" line (embed the following
in the LIBX variable in "conf/sun4", or wherever):
-Bstatic -lXmu -Bdynamic
This is anticipated in a comment in the current copy of "conf/sun4".
NOTE: GNU make is not compatible with the traditional "make", and
is not compatible with spice3. Using GNU make may result in
infinite recursion.
---------- Compiling under MS-DOS with MicroSoft C 5.1:
The PC lacks the program "/bin/sh" (and others) which the above
Unix installation depends on. Instead we have supplied simple
compiling scripts for use with MicroSoft C 5.1. This less
flexible system requires that you edit several files before building:
src/bin/tunepc.c (built-in file locations); Change the values
of the following C variables as appropriate -- leave
double quote and single quote marks as-is, and use
two backslash ('\') characters where you want one:
Spice_Exec_Dir: location you plan to install spice.
Spice_Lib_Dir: location you plan to install the spice
startup and data files.
Spice_OptChar: command line option character
(indicates whether you want to type
"spice -r" or "spice /r").
Def_Editor: location you plan to install spice
AsciiRawFile: location you plan to install spice
The last three options (not listed here) are not
significant under MS-DOS, but should be left as is
(blank).
src/bin/cconf.c Devices and analyses for "cspice"
src/bin/bconf.c Devices and analyses for "bspice"
The initial segment of "cconf.c" and "bconf.c"
are "#define" lines that determine which devices
and analyses should be compiled in to the simulator.
For devices, the line looks like "#define DEV_xxx"
where "xxx" is the name of some device; For
analyses, the line looks like "#define AN_xxx".
Names and descriptions of both analyses and devices
are as listed below ("Devices and Analyses supported
in Spice3f.2", at the end); see also the user's manual.
A reasonable default is supplied with each.
Do not modify anything below the list of '#define'
lines.
(more)
src/include/os_msdos.h
If you do not want the spice-supplied "hardcopy"
routine for sending plots to an IBM Personal
Graphics Printer (or equivalent), comment out the
"#define WANT_PCHARDCOPY" line near the bottom.
Some versions of MS-DOS can't normally send VGA
graphics to a printer.
Once these files have been edited, "cd" into the top directory
(above "util\", "src\", and "conf\") and run "msc51.bat". The
script first sets compiler options in the environment and then
procedes with the compile. Since the environment may not have
enough room, you may have to clear some unused environment
variables before the build, otherwise the build could fail.
Note that these options are only useful for MicroSoft C 5.1 or
later.
Compiler errors are written to the file "src\msc.out". This
includes many warnings because Spice3 was originally written in
pre-ANSI C (or "K&R" C) under Unix. Except for these (numerous)
warnings, Spice3 should compile and run without trouble; see the
next section on installing.
Cleaning up under MS-DOS (after installing):
To delete the original source tree from your hard disk, you may
use the supplied script "util\delall.bat". You must copy
this script outside of the source tree before you run it or it
will remove itself before finishing. Run the script from the top
directory of the source tree (above "util\").
---------- Compiling on the MacIntosh
Since there is no scripting language on the Mac, you must do
considerable work to build spice3 on a Mac. The details
are included in a seperate file, "notes/mac_port".
---------- Installing Spice3
After spice3 and the associated programs have been created, you may
test the program. There are a few test inputs in the "examples"
subdirectory.
Because spice3 is not installed in it's final destination at this
point, you should set the environment variable "SPICE_LIB_DIR" to
the "lib" subdirectory to indicate the location of some startup files.
Finally, you may install spice3 and associated components into
a standard place. Under Unix systems, the command "util/build
system install" will do this automatically (again substitute
your system name or type for "system"). Under MS-DOS or for
the MacIntosh, the files must be copied explicitly.
The executable programs are from the subdirectories "src/bin",
as follows:
spice3 UNIX only: the simulator.
bspice MS-DOS only: a batch mode simulator:
"bspice < input.cir" generates the file
"rawspice.raw", which is read by "nutmeg"
(see below).
cspice MS-DOS only: a spice2 like interface for
small runs (runs out of memory easily).
Use "cspice < input.cir"; generates
'asciiplots' for .plot lines.
nutmeg A stand-alone data analysis program;
Spice3 without the simulation capability.
help A stand alone help browser.
proc2mod Converts process characterization files
to Spice3 BSIM1 MOS model definitions.
sconvert Converts between ascii and binary spice
data files (".raw" files).
multidec A utility for decomposing coupled lossy
transmission lines into equivalent uncoupled
lines. Not available on MS-DOS (need the
"getopt" library).
The following startup/data files are installed from the "lib/"
subdirectory:
helpdir/spice.txt on-line information for spice3.
helpdir/spice.idx index for spice.txt, generated with
the program "bin/makeidx".
scripts/spinit spice/nutmeg commands executed at
startup.
scripts/setplot A script for the command "setplot".
news a start up message of your choosing.
mfbcap graphics-terminal capability database
(not required for MS-DOS).
(Previous versions had a seperate help files for spice3 and
nutmeg; the current help file is now identicle to the "Spice3f4
User's Manual", so there is no distinction).
For the PC and MacIntosh, you must generate the ".idx" files
yourself by running "makeidx spice.txt". Unix "man" pages are
also supplied for the programs spice, nutmeg, and sconvert, for
the mfb database format (looks like termcap), and for the mfb
library. These are not installed automatically as they are
old, unsupported, and may be out of date.
