  (From MUG 20 Contributed by Carol Block of U. C. Berkeley)

  A new version of the popular circuit simulator, Spice3F2, is now avail-
  able from the Industrial Liaison Program (ILP) Office at the University
  of California, Berkeley.  A new release of Octtools will be forthcoming
  in 1993. Enclosed is a list of software distributed by this office.

  Within a few weeks, a new catalog will be available via anonymous FTP.
  Users will also be able to obtain forms, ordering instruc- tions and some
  software via this  means.   Generally,  recipients will  have  to com-
  plete an Agreement Form and pay a documentation and handling fee of about
  $250 per program.

  ILP can now distribute most of  its  programs  in  a  variety  of media,
  including: QIC-120, QIC-150, QIC-320, 8mm (2.2 gig), TK 50 (DEC tape for-
  mat), 9-track 1600 bpi and 9-track 6250  bpi.   Visa and  Mastercard ord-
  ers will be accepted on-line by 1993.  Most of the software may be freely
  redistributed either within an organi- zation  or  to other organiza-
  tions, both within the United States and abroad, subject to the certain
  restrictions,  including  all U.S.   Government restrictions, particu-
  larly those concerning ex- port.

  (from blurb+ftp, in the ILP distribution)

  If you have access to ftp, then the tape is free (you just get to suck it
  over by yourself) and you have to remember to print out the docs yourself
  too.  The usual anonymous ftp rules:

  Other Ports
   -------------------------------------------------------------------- I

  I have a port of the system for SysV, Apollo and HP machines as well
  which is available on request.  Most of these operating systems are
  mature enough now to work directly with Release 7.6.  The system has been
  ported to other non-Unix machines such as VMS, the mac, and various main-
  frame architectures; these latter being a nontrivial effort on the part
  of the individuals involved, but it was accomplished.  I do not have
  these ports; I just know that they are possible because they have been
  performed by others.

20: Berkeley Spice (Current version 3f4)

  (From spice_info on ic.eecs.berkeley.edu)

    Upgrading from Spice 3f2 to 3f4

  The current version is 3f4. This is derived from version 3f2 by applying
  a patch. The patch is available via ftp from ic.eecs.berkeley.edu.

    Acquiring Spice 3f2

  For more information on how to acquire Spice3f2, please send your physi-
  cal mailing address to "ilpsoftware@eecs.berkeley.edu" and request a
  software catalog.  This will give you all of the necessary information
  for ordering Spice3f2 and other Berkeley CAD software, including an order
  form and use agreements.  At last check, the cost for spice3f2 was
  $250.00 (this price may change without notice).

    Systems supported and Formats Supplied

      Spice3f2 has been compiled on the following systems:
          Ultrix 4, RISC or VAX
          SunOS 4, Sun3 or Sun4
          AIX V3, RS/6000
          HP-UX 8.0, 9000/700
          MS-DOS on the IBM PC, using MicroSoft C 5.1 or later

  The following systems have been successfully tested either in the past or
  by someone outside of UC Berkeley.

          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

  Spice3f2 is distributed in source form only.  The C compiler "gcc" has
  been used successfully to compile spice3f2, as well as the standard com-
  pilers for the systems listed above.

  Spice3 displays graphs under X11, PostScript, or a graphics-terminal
  independent library, or as a crude, spice2-like line-printer plot.  On
  the IBM PC, CGA, EGA, and VGA displays are supported through the Micro-
  Soft graphics library.  Note in particular that there is no Suntools
  interface.

  Note the the X11 interface to Spice3 expects release 4 or later, and
  requires the "Athena Widgets Toolkit" ("Xaw") which may be available only
  in the "unsupported" portion of your vendor software.  A version of
  "OpenWindows" has problems due to undefined routines during linking --
  linking with a null copy of these routines has reportedly worked, but
  "OpenWindows" has not been tested in any way for this release.

  Note that for practical performance a math co-processor is required for
  an IBM PC based on the 286 processor.  A math co-processor is also recom-
  mended for the more advanced IBM PC systems.

  (from posting to comp.lsi.cad) The Windows NT port of spice3e2, Spice32,
  is available via ftp from site
  ftp://ftp.cica.indiana.edu/pub/pc/win3/nt/spice100.zip . A similar port
  of nutmeg is included.

  (from Robert Zeff <robert@koko.csustan.edu>)

  I have revised my on line help for Spice32 / Nutmeg32 for Windows NT and
  Win3.1 to Berkeley's version 3F4.  It is available by ftp from
  ftp://csustan.csustan.edu/pub/spice/ .  I have removed the exe-
  cutables for DOD complience.  For access, see the readme file in that
  directory.

  I've updated my Spice circuit simulator to 3F5 and have included the
  BSIM3v3 level 8 mosfet model.  You can get it at

          http://sonnet.com/rzeff

  Sometime it will also be available (ftp) at
  csustan.csustan.edu/pub/spice/i386 or www.zapco.com Yes, it does work on
  Win95.

  The Unix distribution comes on 1/2" 9-track tape in "tar" format, TK50
  tape (DEC tape), or QIC-150 1/4" cartridge tape (Sun cartridge tape).
  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 file names.

    New features in 3f2

  The following is a list of new features and fixes from the previous major
  release of Spice3 (3e.2) (see the user's manual for details):

                  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.

              Additional features since release 3d.2 are:
                  Lossy transmission line model (not available under MS-DOS).
                  Proper calculation of sheet resistance in MOS models.
                  A new command ("where") to aid in debugging troublesome
                          circuits.
                  Smith-chart plots improved.
                  Arbitrary sources in subcircuits handled correctly.
                  Arbitrary source reciprocal calculations and DC biasing
                          now done correctly.
                  Minor bug-fixes to the Pole-Zero analysis.
                  Miscellaneous bug fixes in the front end.

    A Note on Version Numbering

  Spice versions are numbered "NXM", where "N" is a number representing the
  major release (as in re-write), "X" is a letter representing a feature
  change reflected by a change in the documentation, and "M" is a number
  indicating a minor revision or bug-patch number.

    FTP Access and Upgrades

  There is no anonymous ftp access for the Spice3 source(see below). The
  manual for spice3f2 (in it's postscript format) is available via
  anonymous ftp from ftp://ic.eecs.berkeley.edu/pub/spice3/ .  If
  you are interested in the troff/me source, contact the email address
  below (the "make" files and whatnot are somewhat cumbersome for the
  manual).

  Patches or upgrades for Spice3 are _not_ normally supplied, however we
  have made exceptions to this rule, particularly in the case of minor ver-
  sion changes (such as 3f2 to 3f3).

    Email Address for Problems

  Please direct technical inquiries to "spice@berkeley.edu" or "spice-
  bugs@berkeley.edu" (for now these addresses are the same), and ordering
  or redistribution queries to "ilpsoftware@eecs.berkeley.edu".  If you
  find that your email to "spice" or "spice-bugs" doesn't get a response in
  a few days, resend your message.

  (from Jim Nance <jlnance@isscad.com>)

  Hello all circuits people.  I have uploaded source and binaries for Spice
  2g6 to ftp://sunsite.unc.edu/pub/Linux/Incoming/spice2g6.tar.z .  As you
  are probably aware, spice is a circuit simulator, written at Berkeley.
  Version 2g6 was released in 1983.  The current Berkeley version is
  approximatly Spice 3f2, however, Berkeley does not want this distributed.
  Source code for Spice 3e2 did escape from Berkeley and was ported to
  Linux (and a lot of other platforms).  This code has been removed from
  anonymous FTP servers, and is therefore no longer available.  Berkeley
  does publish the source code for Spice 2g6.

  I obtained the source code for Spice from a 386BSD ftp site.  The code
  compiled cleanly, with only minor changes to the Makefile being required.
  I also included an ASCII spice manual which I have found helpful.

  (from Martin Maschmann <martin.maschmann@t-online.de>)

  I can also be reached at <martin.maschmann@vlsi.com>

  I have created a SCHEMATIC CAPTURE program running under X11Rsomething
  (something >=5) for both linux, sunos and SOLARIS. SPICECAD now has a
  home page which has the URL:

          <URL:http://home.t-online.de/home/martin.maschmann>

  There you will find some links to an ftp site from where you can download
  the compiled binaries. Before loading, you can look at some pictures
  which show how the graphics interface looks like. If you don't like it,
  don't load it.

  An english manual is included. Please read the manual!  Example schemat-
  ics are included, too.

  Soure code is not included, because the making of SPICECAD means making
  of SPICE3F4 , which is hard-linked to SPICECAD, making a stripped version
  of GNUPLOT and making the schematic entry part.

  All in all, it is really a mess, especially if you look at the schematics
  part which is VERY hard to understand.

  Customizing SPICECAD for your own needs means: send me a mail which
  explains the problem, and then I can tell you whether I will do it by
  myself (because there could be a wide need for this new feature), or
  whether you can do it by yourself.

  For example, if you want to create an interface for a new simulator (a
  PSPICE interface is still missing, an HSPICE interface will be available
  in the future), I can send you several example files (the interface for
  HSPICE), and you write the interface. Finally , everything can be linked.

  Those who want to add some features I cannot write (because my program-
  ming skills and time is limited) can obtain the source code on a small
  QIC cartridge. What I am thinking of is an EDIF interface. This would be
  a very nice feature.

21: Octtools (Current version 5.1)

  (From the ANNOUNCE-5.1 that comes with it)

  Octtools is a collection of programs and libraries that form an
  integrated system for IC design.  The system includes tools for PLA and
  multiple-level logic synthesis, state assignment, standard-cell, gate-
  matrix and macro-cell placement and routing, custom-cell design, circuit,
  switch and logic-level simulation, and a variety of utility programs for
  manipulating schematic, symbolic, and geometric design data.  Most tools
  are integrated with the Oct data manager and the VEM user interface.

  The software requires UNIX, the window system X11R4 including the Athena
  Widget Set. The design manager VOV and a few other tools require the C++
  compiler g++.

  Octtools-5.1 have been built and tested on the following combinations of
  machines and operating systems: DECstation 3100, 5000 running Ultrix 4.1
  and 4.2; DEC VAX running Ultrix 4.1 and 4.2; Sun 3 and 4 running OS 4.0
  and Sun SparcStation running OS 4.0.  The program has been tried on the
  following machines, but is not supported: Sequent Symmetry, IBM RS/6000
  running AIX 3.1.

  To obtain a copy of Octtools 5.1 (8mm, tk50, or 1/4inch cartridge QIC150)
  and a printed copy of the documentation) for a $250 distribution charge,
  see section on Berkeley ILP.

  Questions may be directed to octtools@ic.eecs.berkeley.edu.

22: Ptolemy (Current version 0.5):

  (From comp.lsi.cad)

   What is Ptolemy:
   ---------------

  Ptolemy provides a highly flexible foundation for the specification,
  simulation, and rapid prototyping of systems.  It is an object oriented
  framework within which diverse models of computation can co-exist and
  interact.  For example, using Ptolemy a data-flow system can be easily
  connected to a hardware simulator which in turn may be connected to a
  discrete-event system, etc.  Because of this, Ptolemy can be used to
  model entire systems.

  Ptolemy also has code generation capabilities.  From a flow graph

  description, Ptolemy can generate C code and DSP assembly code for rapid
  prototyping.  Ptolemy can also generate Silage and VHDL descriptions for
  hardware synthesis.

  Ptolemy has been used for a broad range of applications including signal
  processing, telecomunications, parallel processing, wireless communica-
  tions, network design, radio astronomy, real time systems, and
  hardware/software co-design.  Ptolemy has also been used as a lab for
  signal processing and communications courses.  Currently Ptolemy has hun-
  dreds of users in over 100 sites, both in industry and academia.

  Ptolemy is available for the Sun 4 (sparc), DecStation (MIPS), and HP
  (HP-PA) architectures. Installing the system requires 90 Mbytes for
  Ptolemy (more if you optionally remake).  Ptolemy also requires at least
  8 Mbytes of physical memory.

   Getting the New Release:
   -----------------------

  Ptolemy is available via anonymous ftp at:
  ftp://ptolemy.eecs.berkeley.edu/pub/ This site contains the entire
  Ptolemy distribution, a postscript version of the Ptolemy manual, and
  several Ptolemy papers.

          For those unfamiliar with anonymous ftp, here's what you need to do:
          1.   FTP to Internet host "ptolemy.eecs.berkeley.edu"  (128.32.240.78)
          2.   Login as "anonymous"; use your full email address as the password
          3.   cd pub
          4.   get the README file and follow its instructions.

          Organizations without Internet FTP capability can obtain Ptolemy
          without support from ILP:

                  EECS/ERL Industrial Liaison Program Office
                  Software Distribution
                  205 Cory Hall

                  (510) 643-6687
                  email: ilpsoftware@eecs.berkeley.edu

  This includes printed documentation, including installation instructions,
  a user's guide, and manual pages.  A handling fee (on the order of $250)
  will be charged.

23: Lager (Current version 4.0):

  (From MUG 18)

  The LAGER system is a set of CAD tools for performing parameterized VLSI
  design with a slant towards DSP applications (but not limited to DSP
  applications).  A standard cell library, datapath library, several module
  generators and several pad libraries comprise the cell library.  These
  tools and libraries have originated from UC Berkeley, UCLA, USC, Missis-
  sippi State, and ITD.  The tool development has been funded by DARPA
  under the Rapid Prototyping Contract headed by Bob Brodersen (UC Berke-
  ley).  LAGER 3.0 was described in MUG 15.

  Send email to reese@erc.msstate.edu if you are interested in obtaining
  the toolset via FTP. If you cannot get the distribution via ftp then send
  one 1/4" 600 ft. tape OR an 8 mm tape (Exabyte compatible) to Bob Reese
  by phone at (601)-325-3670 or at one of the following addresses:

          (US Mail Address)
          P.O. Box 6176
          Mississippi State, MS 39762

          (FEDEX)
          2 Research Boulevard
          Starkville, MS 39759

  Be sure to include a return FEDEX waybill we can use to ship your tape
  back to you. Instead of sending a tape and FEDX waybill, you can also
  just send us a check for $75 and we will send you back a tape.  Make the
  check payable to Mississippi State Univ.  The tape will be written on a
  high density tape drive (150 Mb).  Older low density SUN tape drives (60
  Mb) cannot read this format so you need to have access to one of SUN's
  newer tape drives.

24: BLIS (Current version 2.0):

  (From their announcement posted here)

  BLIS (Behavior-to-Logic Interactive Synthesis) is an environment for the
  synthesis of digital circuits from high-level descriptions.  Version 2.0
  supports functional-level synthesis starting from the ELLA hardware
  description language.  Other languages can easily be supported by inter-
  facing a parser to the internal data-flow representation of BLIS.

  BLIS is distributed through the Industrial Liason's Program (ILP) Office
  of the UCB EECS department.  The cost of $250 covers media and distribu-
  tion charges.  Binaries are provided for SUN4 and DEC MIPS architectures
  but BLIS should compile on most other machines supported by the GNU C and
  C++ compilers (e.g. HP, vax, etc).  ELLA language documentation and simu-
  lator are not supplied with the BLIS distribution, but can be obtained
  from Computer General.

25: COSMOS and BDD

  (From their announcement posted here)

                Obtaining and installing COSMOS and BDD.

  The COSMOS package generates switch-level simulators for MOS circuits.
  The BDD package is a subset of COSMOS providing a set of library routines
  for symbolic Boolean manipulation.

  To obtain a copy of either COSMOS or BDD via FTP:

  1. Create an appropriate subdirectory.  For COSMOS, you may want to
     create a symbolic link /usr/cosmos to this directory, although this is
     not essential.

  2. Connect to the subdirectory

  3. FTP to ftp://n3.sp.cs.cmu.edu/usr/cosmos/ (login anonymous, pass-
     word yourname@your.host.name)

  4. Type:

             cd /usr/cosmos/ftp
             ls

  5. Select which version of the code you want.  The files are named
     bdd.XXX.YYY.tar.Z and cosmos.XXX.YYY.tar.Z, where XXX.YYY is the ver-
     sion number.  Generally you should select the highest numbered ver-
     sion.

  6. 6. Type:
             get <FILE> (where <FILE> is the file name of the selected ver-
     sion).
             get README
             quit

  7. Follow the instructions in README

  8. Send the following information to cosmos@cs.cmu.edu

             Your name
             Your postal address
             Your net address
             The file retrieved
             The date of your retrieval

  COSMOS and BDD are made available with the understanding that no part of
  it will be redistributed further without permission.

  26: ITEM

  (Taken from the item.news file contained in the package:)

  The first public release of ITEM, UCSC's logic minimizer using if-then-
  else DAGs, was made 2 January 1991.  The system is available by anonymous
  ftp from ftp://ftp.cse.ucsc.edu/pub/item/item.tar.Z .  Also available are
  tech reports about the algorithms and data structures (88-28, 88-29, and
  90-43).

  ITEM can also be found at ftp://ftp.cse.ucsc.edu/pub/item directory.

27: PADS logic/PADS PCB:

  While this is a commercial product, they have just recently made avail-
  able a shareware version.  This version is fully functional and indenti-
  cal to their schematic capture and PCB autoplace and route software
  except that it is limited to about 50 components.  It is available for
  IBM PC/PC compatibles directly from PADS, or from anynonmous ftp at
  several sites including
  <URL:ftp://wuarchive.wustl.edu:/systems/ibmpc/simtel/cad/>.
  There is a $50 registration fee if you would like to get future updates
  from them.

28: Another PCB Layout Package:

  (from Randy Nevin <randyn@microsoft.com>:)

  I am distributing a freely-copyable printed circuit board (pcb) autorout-
  ing software package called PCBCAD. It runs on PC-compatible computers,
  and requires EGA resolution. All source code is included. It contains: a
  "ratnest" viewer, autorouters for 1- and 2-layer boards, a board viewer,
  hard copy output programs for hp laserjet and postscript printers, and a
  DXF converter (autocad). For more background on autorouting, see the
  related article published in the September 1989 Dr. Dobb's Journal. In a
  nutshell, what you do is create an ascii file which describes your cir-
  cuit, feed it to the autorouter, and the circuit will be routed for you.
  To receive the programs, send a stamped, self-addressed floppy mailer and
  a floppy to:

          Randy Nevin,
          24135 SE 16th PL
          Issaquah, WA 98029, USA
          internet: randyn@eskimo.com.

  The programs are also available via ftp from

          <URL:ftp://oak.oak.and.edu/SimTel/msdos/cad/pcbca110.zip>
          <URL:ftp://oak.oak.and.edu/SimTel/msdos/cad/pcbcattl.zip>

29: Magic (Current version 6.5):

  This is a polygon based lsi layout editor.  It is capable of reading and
  writing magic, calma (version 3.0, corresponding to GDS II Release 5.1),
  and cif.  It is available for anonymous ftp from
  ftp://gatekeeper.dec.com/pub/DEC/magic .

  Linux versions of magic are available from the standard linux mirror
  archives, such as ftp://dorm.rutgers.edu/pub/linux/sources/usr.bin.X11/
  [128.6.18.15]:

             ftp://dorm.rutgers.edu/pub/linux/sources/usr.bin.X11/
             ftp://dorm.rutgers.edu/pub/linux/sources/usr.bin.X11/

  A short summary of the problems people have experienced in using Magic
  6.3 under Linux is available:

                  ftp://magnet.fsu.edu/users/murali/

  (from Bob Mayo <mayo@pa.dec.com>)

  Magic 6.4 is a minor update of magic. It includes the patches from the
  6.3 notes series, as well as ports to Digital's Alpha AXP OSF/1 worksta-
  tions (courtesy of Stefanos Sidiropoulos) and to Linux on a PC (courtesy
  of Harold Levy).

  This release includes an updated copy (version 9.2) of Stanford's Irsim
  program, as well as scmos tech files (version 8.0.0) from MOSIS.

  The easiest way to get magic is via the World Wide Web:

                  <URL:http://www.research.digital.com/wrl/magic/magic.html>

  If you don't have web access, use anonymous FTP from gatekeeper.dec.com
  in the directory pub/DEC/magic/6.4. This directory also include the file
  irsim-9.2.tar.Z.

  (from Tom Burd <burd@eecs.berkeley.edu>)

  If you have layout you can extract, try using irsim-cap, a modified ver-
  sion of irsim.  switched level simulation gives results close to spice
  (within 20% for certain (rail-to-rail) circuits... CMOS, nora, domino,
  etc.  stuff like CPL, some differential logic styles, etc. gives irsim
  problems in its estimation).  And it is _much_ faster than SPICE.  We
  simulate upwards of 100k xsistor chips, but it takes a good CPU and lots
  of memory. You can download
  such:<URL:ftp://infopad.eecs.berkeley.edu/pub/irsim-cap.tar.Z>

  (from comp.lsi.cad)

  Newer versions of magic (6.5) and irsim (9.4) are now available through
  the magic web page:

          <URL:http://www.research.digital.com/wrl/projects/magic/magic.html>

  Magic 6.5 is yet another upgrade of magic. It includes all patches posted
  since the introduction of 6.4.4 and integrates ports to Solaris and
  Free-BSD.  Additionally it includes:

          New versions of ext2sim and ext2spice.
          Cif/Calma enhancements
          DRC enhancements
          Some new commands.
          The latest version of the mosis technology file.

  Magic-6.5 is distributed with irsim-9.4. This new version deals with the
  sim file format produced by magic-6.5 and it also includes support for
  power estimation and writing user modules in C.

  The system has been compiled and tested in a number of systems (solaris,
  irix, ultrix, linux, sunos, hpux to name a few). However the usuall dis-
  claimers about the no-maintenance mode apply: I can't promise that I will
  fix any bugs (which I am sure that exist) but I will do my best.

  Comments and bug reports/patches should be posted to the magic hypermail
  archive: magic-hypermail@pa.dec.com
