- 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.
