  MOSIS Users' Group (MUG) are now available via anonymous ftp from
  "venera.isi.edu" (128.9.0.32) in directory "pub/mug".  The files "readme"
  and "index" should be retrieved first.  These files are provided "as is",
  but may prove very helpful to those using the MOSIS integrated circuit
  prototyping service.

2: Improved spice listing from magic.

  (If someone has put together a working solution for some or all of the
  following issues, send me a note.  It would be great if this issue could
  be resolved once and for all.  Preferably, also for standard mosis tech-
  nology.)

  Hierarchical extractions with net names: ext2spice done by Andy Burstein
  <burstein@zabriskie.berkeley.edu>.

  Poly and well resistance extraction: There are persistent rumors that
  people have this working, however, all I have seen is extracted poly
  resistor with each end shorted together, ie each end has the same node
  name/number.

  (This is the most annoying problem that I typically encounter daily.  If
  ANYONE knows a fix for this, please tell us! I wrote a real quick and
  dirty set of scripts/programs to edit the magic file.  It will break the
  poly contacts and relabel them.  This is a real hack, but all other solu-
  tions require modification of the magic code itself.  This procedure only
  works with an extractor that handles labeled nodes, i.e. ext2spice from
  above.  --WH)

  Area/perimeter of source and drain extraction: Magic 6.3 does not appear
  to correctly extract the geometry into the .ext file, and so any
  ext2spice program that uses the .ext value is incorrect.

3: Tips and tricks for magic (Version 6.3)

  Searching for nets:

  Yes, magic does actually let you search for node names.  Use :specialopen
  netlist.  Then click on the box underneath label, you will be prompted
  for the name of the label you want to search for.  Enter the name, and
  then press enter twice.  Click on show, and then find, magic will then
  highlight the net.

  Bulk node extraction:

  Problems with getting the bulk node to extract correctly?  Try labeling
  the well with the node name that it is connected to.

  Painting Wells:

  Supposedly :cif in magic will automatically paint in the wells correctly.
  However this is not always the case.  If you are using mosis 2u technol-
  ogy, and your wells are getting strange notches in them, you might try
  changing the grow 300 shrink 300 lines in your lambda=1.0(pwell) and
  lambda=1.0(nwell) cif sections of your tech file to grow 450 shrink 450.
  (Remember you can use :cif see CWN to see nwell, if :cifostyle is nwell,
  or :cif see CWP to see pwell if its pwell technology to preview what will
  be done with the well.  You may use :feedback clear to erase what it
  shows you.)

4: What can I use to do good plots from magic/CIF?

  (Thanks to Douglas Yarrington <arri@ee.eng.ohio-state.edu> and Harry
  Langenbacher <harry@neuronz.Jpl.Nasa.Gov>, for feedback here.)

  CIF:

  CIF stands for CalTech Intermediate Form. It's a graphics language which
  can be used to describe integrated circuit layouts.

  cif2ps  version 2 (Gordon W. Ross, MITRE):

  A much better version of cif2ps, extending the code of cif2ps (Marc
  Lesure, Arizona State University) and cifp (Arthur Simoneau, Aerospace
  Corp).  It features command line options for depth and formatting.  Can
  extend one plot over several pages (up to 5 by 5, or 25 pages). By
  default, uses a mixture of postscript gray fill and cross-hatching.
  Options include rotating the image, selecting the hierarchy depth to
  plot, and plotting style customization.  Plots are in B/W only.

  It was posted to comp.sources.misc, and is available by ftp from
  uunet.uu.net(192.48.96.2) as: comp.sources.misc/volume8/cif2ps.Z.

  cifplot:

  Cifplot plots CIF format files on a screen, printer or plotter.  Cifplot
  reads the .cif file, generates a b/w or color raster dump, and sends it
  to the printer.  Plots can be scaled, clipped, or rotated.  Hierarchy
  depth is selectable, as well as the choice of colormap or fill pattern.
  An option exists which will compress raster data to reduce the required
  disk space.  For those plotting to a Versatec plotter, there is also a
  printer filter/driver available called vdmp.

  cifplot (m2c version, from chiang@m2c.org <Rit Chiang>):

  The cifplot program from M2C is not in public domain.  However, we do
  provide P.D. CAD tools to university for a fee of $2500/year to cover our
  cost on distribution, telephone hotline support, documentation and
  tutorials, etc., under our CUME (Clearinghouse for Undergraduate
  Microelectronics Education) program.  This program, in the past, was sub-
  sidized by NSF.

  The cifplot program was modified by M2C to support plotting for B&W
  PostScript and color PostScript printers, besides the versatec plotters.
  We also provide plotting services for people who sent us a cif file.  The
  cost is $20/per 24" color versatec plot for University and $50 for oth-
  ers.

  For more information on the CUME program or the plotting service, please
  send e-mail to hotline@m2c.org.

  oct2ps (available as part of the octtools distribution):

  It is possible to convert your .mag file to octtools, and then you may
  use oct2ps to print it.

  Both cif2ps and oct2ps work well for conversion to postscript.  They do
  look slightly different, so pick your favorite.  Note that cif2ps can be
  converted to adobe encapsulated postscript easily by adding a bounding
  box comment.  oct2ps does convert to color postscript, which can be a
  plus for those of you with color postscript printers.

  Flea:

  Flea ([F]un [L]oveable [E]ngineering [A]rtist) is a program used to plot
  magic and cif design files to various output devices. Parameters are
  passed to flea through the flags and flag data or through .flearc files
  and tech files.  Supports: HP7580 plotter, HP7550 hpgl file output,
  HP7550 plotter lpr output, Postscript file output, Laser Writer lpr out-
  put, Versatec versaplot random output.  Options include: Does line draw-
  ings with crosshatching for postscript, versatec, and hp plotters.  Many
  options (depth, label depth, scale, path, format...)

  Available by ftp from zeus.ee.msstate.edu in pub/flea.tar.Z.

  pplot:

  Can output color PostScript from CIF files. The source is available from:
  tesla.ee.cornell.edu in /pub/cad/pplot.tar.Z. It only generates PS files
  (including color PS), and there's no support for EPS files.  It is lim-
  ited in its support of cif commands.  (Wire, roundflash, and delete are
  not supported.)  It only supports manhattan geometry (Polygons and rota-
  tions may only be in 90 degree multiples.)

  vic:

  Part of the U. of Washington's Northwest Lab, for Integrated Systems Cad
  Tool Release (previously UW/NW VLSI Consortium).  Does postscript and HP
  pen plotters.  Only available as part of the package.

  CIF/Magic -> EPS -> groff/latex

  Currently no prgram here directly generates EPS files.  It is possible to
  add an EPS bounding box (%% BoundingBox: l t b r) to the output from
  these programs to get an EPS file.  Alternatively, ps2eps or ps2epsf may
  be used.

5: What tools are used to layout verification?

  Gemini:

  This is an excellent program that was done by Carl Ebeling.  I am not
  sure if he is still working on developing additional features or not.
  The program will compare two sim format netlists, and check w/l values.
  As far as I know it only supports three terminal devices.

  Recently, I contacted several foundries to determine  which  com- panies
  are  interested  in fabricating small to moderate lots of wafers for cus-
  tom CMOS designs.  I believe many of the readers of this  column are
  designers who wish to have fabricated only 1,000 to 20,000 parts per
  year.  There are currently several  prototyp- ing  services  (e.g. MOSIS
  and Orbit) that can produce fewer than 100 parts for about $100 each and
  there are  also  several  foun- dries  which  are willing to produce
  100,000 custom parts for $5- $20 each (depending on the die size and
  yield).  My  purpose  was to  identify  those companies filling the large
  gap between these two services.

  The prices in the table below are a result of averaging the  data sup-
  plied by four foundries.  The raw data varied by more than +/- 40% so the
  information should be used only in the early stages of budgetary  plan-
  ning.   Once  the design specifications are fairly well known, the
  designer should contact one or more foundries  to obtain  specific
  budgetary  quotes.  As the design nears comple- tion, binding quotes can
  then be obtained.

  The following assumptions were made by the foundries:

  All designs will require custom CMOS wafer  fabrication  using  a
  double-metal, single-poly process with a feature size between 2.0 and 1.2
  microns.  The designs may contain some  analog  circuitry and  some  RAM
  so the yield has been calculated pessimistically.  The dies will be pack-
  aged and tested at 1  MHz  using  a  Sentry- type digital tester for 5-10
  seconds per part.  The customer will furnish the test vectors.

  Would anyone like to comment on experiences or problems that they have
  seen with MOSIS, or parametric testing results that are of general
  interest?  Perhaps, experience with mosis nwell low noise versus standard
  nwell.

14: Converting from/to GDSII/CIF/Magic

  Magic version 6.3 is capable of reading and writting to all three for-
  mats.  (From the magic man page):

  calma [option] [args]

  This command is used to read and write files in Calma GDS II Stream for-
  mat (version 3.0, corresponding to GDS II Release 5.1).  This format is
  like CIF, in that it describes physical mask layers instead of Magic
  layers.  In fact, the technology file specifies a correspondence between
  CIF and Calma layers.  The current CIF out- put style (see cif ostyle)
  controls how Calma stream layers are generated from Magic layers.

  cif [option] [args]

  Read or write files in Caltech Intermediate Form (CIF).

15: CFI (CAD Framework Initiative Inc.)

  (From Randy Kirchhof <rkk@cfi.org>)

  For those of you who may be unfamiliar with our work, The CAD Framework
  Initiative Inc. was formed in May 1988. We're located in Austin, TX,
  although we're a distributed company. We're a  not-for- profit consortium
  formed under the laws of the state of Delaware.  Our charter is to gain
  consensus from industry users, the academic community, and vendors, to
  develop guidelines for an industry acceptable CAD framework implementa-
  tion.

  A CAD framework is a software infrastructure which provides a common
  operating environment for CAD tools.  Through a framework, a user should
  be able to launch and manage tools, create, organize, and manage data,
  graphically view the entire design process and perform design management
  tasks such as configuration management, version management, etc.

  CFI is well into the final stages prior to release 1.0. We recently
  returned from the DAC convention in Anaheim, where there was an extraor-
  dinary amount of interest shown in our Pilot project demonstrations. We
  were able to demonstrate robust, working CFI-compliant software from a
  large number of member companies.  Cooperation in our ongoing effort has
  been very good from our outset.

  Also, please be aware that CFI has virtually all of our working documents
  online, available via anonymous FTP to cfi.org. (192.138.153.1) There is
  also an e-mailserver. Send an empty message to cfi-server@cfi.org. The
  mail server & FTP use the same directory.

  CFI Release 1.0 is on schedule, up for final ballot in October and will
  be formally released in December of this year. Many vendors will ini-
  tially release CFI compliant software as early as 2Q 1993.

  17: Berkeley Spice (Current version 3e2)

  (From spice_info on ic.berkeley.edu)

  Berkeley Spice this is no longer freely distributable.  (This includes
  even old versions of spice3.)  Documentation is available on
  ic.berkeley.edu.  General information is available from
  "spice@berkeley.edu".  For more information on how to acquire Spice,
  please send your physical mailing address to "cindy@janus.berkeley.edu"
  and request a software catalog.  This will give you all of the necessary
  information for ordering Spice3e2 and other Berkeley CAD software,
  including an order form and use agreements.  At last check, the cost for
  spice3e2 was $250.00 (this price may change without notice).

  Spice3e2 has been compiled on the following systems:
          DECstation/VAXstation/VAX       Ultrix 4.x      X11r4
          Sun3/Sun4                       SunOS 4.x       X11r4
          IBM RS/6000                     AIX V3          X11r3
          SGI Personal Iris               Irix 3.2
          Sequent Symmetry or Balance     Dynix 3.0       X11r4
          HP 9000/300                     HP-UX 7.0
          NextStation                     Next 2.0
          IBM PC (or compatible)          MS-DOS 3.x/Microsoft C 5.1 or later


  Spice3e2 is distributed in source form only.  The C compiler "gcc" has
  been used successfully to compile spice3e2, as well as the standard com-
  pilers for the systems listed above.  Note the the X11 interface to
  Spice3 requires the "Athena Widgets Toolkit" ("Xaw") which may be avail-
  able only in the "unsupported" portion of your vendor software.  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 MicroSoft graphics
  library.  Note in particular that there is no Suntools interface.

  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.

  The Unix distribution comes on 1/2" 9-track 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 distri-
  butions are identical, including file names.

  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.

  We anticipate that FUTURE distributions will also come on QIC-150 1/4"
  (a.k.a. "Sun cartridge tape" high density or 150MB 1/4" tape), and a
  compressed tar files on two 3.5" diskettes for Sun or VAX systems with
  3.5" drives.  * Note that these future formats are anticipated but not
  guaranteed and do NOT apply for Spice3e2 *.

  There is no anonymous ftp access for the Spice3 source.  The manual for
  spice3e2 (in it's troff/me format or postscript format) is available via
  anonymous ftp from "ic.berkeley.edu" in the directory "pub/spice3".
  Patches or upgrades for Spice3 are _not_ normally supplied, however we
  have made exceptions to this rule.

18: 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,

19: 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.

20: 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.

  Ordering information can be obtained from:

21: 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.cse.ucsc.edu, in directory pub/item as a compressed tar
  archive (item.tar.Z).  Also available are tech reports about the algo-
  rithms and data structures (88-28, 88-29, and 90-43).

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

22: 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 wuarchive.wustl.edu in
  /mirrors/msdos/cad/pads*.zip.  There is a $50 registration fee if you
  would like to get future updates from them.

23: Another PCB Layout Package:

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

  I'm distributing a freely-copyable software package to do autorouting of
  (1- and 2-layer) printed circuit boards on a PC or compatible. It is
  written in C (with a little .asm), and all source code is included. There
  is an autorouter, a board viewer, a rat nest viewer, and some output
  filters which generate postscript and hp laserjet output files. There is
  no charge, but I maintain the copyright (it is not public domain). If you
  want to read about it, I published an article on autorouting algorithms
  in the sept '89 dr. dobb's journal. ega is required (for the viewing pro-
  grams). If you'd like to get the software, send me a stamped, self-
  addressed floppy mailer and a floppy. I can handle 5.25" 360K or 1.2M, or
  3.5" 1.4M, but if you send 360K there is some extra code that I won't be
  able to fit on the disk, so high density is better.

  I developed this software at home on my own time, and it is not related
  to what I do for my employer, so I will not use my employer's email
  resource to distribute it. however, it is available for anonymous ftp
  access on wsmr-simtel20.army.mil in PD1:<MSDOS.CAD>PCB.ARC, last I heard.
  I do not keep simtel up to date. But the version there is useable, and
  does include all source code.

24: Magic (Current version 6.3):

  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 gatekeeper.dec.com in

  /pub/DEC/magic.







25: PSpice:

  This is a commercial product, however, they do have a student version
  that is available (limited to around 16 transistors).

26: Esim:

  A new version of the switch-level simulator ESIM that can handle CMOS
  transmission gates is available through MUG, ftp venera.isi.edu
  (128.9.0.32))

27: Isplice3 (Current version 2.0):

  This is a high level simulator, I do not know much more then that.  It is
  available via anonymous ftp from uicadb.csl.uiuc.edu.

28: Watand:

  (From Phil Munro's posting <FC138001@ysub.ysu.edu>)

  Spice is not the only circuit simulator available.  There is one called
  WATAND (WATerloo ANalysis and Design) which runs on a mainframe (and some
  other workstations).  We use it here under CMS on our mainframe computer.

  Unlike Spice and its derivatives, Watand is a fully *interactive* pro-
  gram; that is, one enters an environment where analyses can be run and
  rerun, values changed and queried, options changed, and even different
  circuits can be run, all without leaving the environment.

     "WATAND Users Manual", by Dr. Phil Munro, April 1992, 233 pages,
     unbound, $7.00 plus whatever shipping charges the bookstore might ask
     of you.

     "WATAND Introduction and Examples", by Dr. P. Munro, September 1991,
     160 pages, spiral bound, incomplete edition Chapters 1 - 10.  The cost
     is $4 or $5, I think, plus shipping.

               You should write to Youngstown State University Bookstore
                               Youngstown, Ohio 44555


  Watand itself is available from Mark O'Leavey, Waterloo Engineering
  Software, 22 King St. S., Suite 302, Waterloo, Ontario, CANADA, N2L 1C6.
  Fax: (519) 746-7931 Phone: (519) 741-8097. It's currently only available
  for DECStation and Sparcstation.

29: Caltech VLSI CAD Tools:

  (From John Lazzaro <lazzaro@boom.CS.Berkeley.EDU>)

                     Caltech VLSI CAD Tool Distribution


  We are offering to the Internet community a pre-release version of the
  Caltech electronic CAD system for analog VLSI neural networks.  This dis-
  tribution contains tools for schematic capture, netlist creation, and
  analog and digital simulation (log), IC mask layout, extraction, and DRC
  (wol), simple chip compilation (wolcomp), MOSIS fabrication request gen-
  eration (mosis), netlist comparison (netcmp), data plotting (view) and
  postscript graphics editing (until). These tools were used exclusively
  for the design and test of all the integrated circuits described in
  Carver Mead's book "Analog VLSI and Neural Systems".  Until was used as
  the primary tool for figure creation for the book.  The distribution also
  contains an example of an analog VLSI chip that was designed and fabri-
  cated with these tools, and an example of an Actel field-programmable
  gate array design that was simulated and converted to Actel format with
  these tools.

  These tools are distributed under a license very similar to the GNU
  license; the minor changes protect Caltech from liability.

  To use these tools, you need:

  1) A unix workstation that runs X11r3, X11r4, or Openwindows

  2) A color screen

  3) Gcc or other ANSI-standard compiler

  Right now only Sun Sparcstations are officially supported, although
  resourceful users have the tools running on Sun 3, HP Series 300, and
  Decstations.  If don't have a Sparcstation or an HP 300, only take the
  package if you feel confident in your C/Unix abilities to do the porting
  required; someday soon we will integrate the changes back into the
  sources officially, although many "ifdef mips" are already in the code.

  If you are interested in some or all of these tools,

  1) ftp to hobiecat.cs.caltech.edu on the Internet,

  2) log in as anonymous and use your username as the password

  3) cd ~ftp/pub/chipmunk

  4) copy the file README, that contains more information.

  European researchers can access these files through anonymous ftp using
  the machine ifi.uio.no in Norway; the files are in the directory chip-
  munk.  We are unable to help users who do not have Internet ftp access.

30: Switcap2 (Current version 1.1):

  This is a switched capactor simulator.  It is available from:

                  SWITCAP Distribution centre,
                  411 Low Memorial Library,
                  New York,

31: Test Software for Abramovici Text:

  (Contributed by Mel Breuer of the Univ. of Southern California)

  Many faculty are using the text by Abramovici, Breuer, and Fried- man
  entitled  "Digital Systems Testing and Testable Design" in a class on
  testing.  They have expressed an interest to  supplement their  course
  with software tools.  At USC we have developed such a suite of tools.
  They include a  good  value  simulator,  fault simulator,  fault  col-
  lapsing  module, and D-algorithm-based ATPG module for combinational
  logic.  The software has  been  specifi- cally  designed  to  be easily
  understood, modified and enhanced.  The algorithms follow those described
  in the text.  The  software can  be  run  in many modes, such as one
  module at a time, single step, interactively or as a batch process.  Stu-
  dents can use  the software  "as  is"  to  study  the operation of the
  various algo- rithms, e.g. simulation of a latch using different delay
  models.  Also,  simple  programming  projects can be given, such as
  extend the simulator from a 3-valued system to  a  5-valued  system;  or
  change  the D-algorithm so that it only does single path sensiti- zation.
  There  are  literally  over  50  interesting   software enhancements
  that  can  be made by changing only a small part of the code.  The system
  is written in C and runs on a SUN.

  If you are currently using the Abramovici text and would  like  a copy
  of  this  software,  please  send a message to Prof. Melvin Breuer at
  mb@poisson.usc.edu.

32: Test Generation and Fault Simulation Software

  (Contributed by Dr. Dong Ha of Virginia Tech)

  Two automatic test pattern generators (ATPGs) and a fault simula- tor
  for  combinational circuits were developed at Virginia Tech, and the
  source codes of  the  tools  are  now  ready  for  public release.
  ATLANTA is an ATPG for stuck-at faults.  It is based on the FAN algorithm
  and a parallel-pattern,  single-fault  propaga- tion  technique.   It
  consists of optional sessions using random pattern testing, deterministic
  test pattern generation  and  test compaction.  SOPRANO is an ATPG for
  stuck-open faults.  The algo- rithm of SOPRANO is similar to  ATLANTA
  except  two  consecutive patterns  are  applied  to  detect a stuck-open
  fault.  FSIM is a parallel-pattern, single-fault  simulator.   All  the
  tools  are written  in  C.  The source codes are fully commented, and
  README files contain user's manuals.  Technical papers about  the  tools
  were  presented at DAC-90 and ITC-91. All three tools are free to univer-
  sities.  Companies are requested to make a contribution  of $5000  but
  will have free technical assistance.  For detailed in- formation, con-
  tact:

33: Olympus Synthesis System

  (From Rajesh K. Gupta <rgupta@sirius.Stanford.EDU>)

  Recently there have been several enquiries about the Olympus Synthesis
  System. Here are answers to some commonly asked questions. For details
  please send mail to "synthesis@chronos.stanford.edu".

  1. What is Olympus Synthesis System?

  Olympus is a result of a continuing project on synthesis of digital cir-
  cuits here at Stanford University. Currently, Olympus synthesis system
  consists of a set of programs that perform synthesis tasks for synchro-
  nous, non-pipelined circuits starting from a description in a hardware
  description language, HardwareC.

  The output of synthesis is a technology independent netlist of gates.
  This netlist can be input to logic synthesis and technology mapping tools
  within Olympus or to UC Berkeley's mis/sis. Current technology mapping in
  Olympus is targeted for LSI logic standard cells and a set of PGA archi-
  tectures: Actel and Xilinx.

  2. How is Olympus distributed?

  The source code and documentation for Olympus is distributed via ftp.

  3. What are the system requirements for Olympus?

  Olympus has been tested on following hardware platforms: mips, sparc,
  hp9000s300, hp9000s800, hp9000s700, vax.  All the programs in Olympus
  come with a default menu-driven ASCII interface. There is also a graphi-
  cal user interface, called "olympus", provided with the distribution.
  This interface is written using Motif procedures.

  You would need about 40 MBytes of disk space to extract and compile the
  system.

  4. How can I obtain a copy of Olympus?

  Olympus is distributed free of charge by Stanford University.  However,
  it is not available via anonymous ftp. In order to obtain a copy please
  send a mail to "olympus@chronos.stanford.edu" where an automatic-reply
  mailer would send instructions for obtaining Olympus software.

34: OASIS logic synthesis

  (From William R. Richards Jr. <richards@mcnc.org>)

  OASIS is a complete logic synthesis system based on the Logic3 HDL
  develped at MCNC (unfortunately neither VHDL or Verilog compatible).
  kk@mcnc.org is the person responsible for it. OASIS is available to US
  universities for $500 and non-US universities for $600. Industrial
  license is $3000.

35: CAzM, a Spice-like table-based analog circuit simulator

  (From William R. Richards Jr. <richards@mcnc.org>)

  Second is CAzM, a Spice-like table-based analog circuit simulator. It
  offers significant performance advantages over other Berkeley Spice
  derivatives. It is used fairly extensively in our design community.  US
  university license is $175, non-US $250. Commercial license is $800. It
  comes with an X11- based signal viewing tool Sigview which is public
  domain and may be anonymous ftp'd from mcnc.org. I am the primary contact
  for CAzM at MCNC.
