<H3>PREFACE</H3>
<P>In 1988 I began to teach full-custom VLSI design. In 1990 I started teaching
ASIC design instead, because my students found it easier to get jobs in
this field. I wrote a proposal to The National Science Foundation (NSF)
to use electronic distribution of teaching material. Dick Lyon helped me
with preparing the first few CD-ROMs at Apple, but Chuck Seitz, Lynn Conway,
and others explained to me that I was facing a problem that Carver Mead
and Lynn had experienced in trying to get the concept of multichip wafers
adopted. It was not until the publication of the Mead-Conway text that people
accepted this new idea. It was suggested that I must generate interest using
a conventional format before people would use my material in a new one (CD-ROM
or the Internet). In 1992 I stopped writing papers and began writing this
book — a result of my experiments in computer-based education.
I have nearly finished this book twice. The first time was a copy of my
notes. The second time was just before the second edition of Weste and Eshragian
was published — a hard act to follow. In order to finish in 1997
I had to stop updating and including new ideas and material and now this
book consists of three parts: Chapters 1-8 are an introduction to ASICs,
9-14 cover ASIC logical design, and 15-17 cover the physical design of ASICs.</P>
<P><A NAME="anchor331922"></A>The book is intended for a wide audience.
It may be used in an undergraduate or graduate course. It is also intended
for those in industry who are involved with ASICs. Another function of this
book is an "ASIC Encyclopedia," and therefore I have kept the
background material needed to a minimum. The book makes extensive use of
industrial tools and examples. The examples in Chapters 2 and 3 use tools
and libraries from MicroSim (PSpice), Meta Software (HSPICE), Compass Design
Automation (standard-cell and gate-array libraries), and Tanner Research
(L-Edit). The programmable ASIC design examples in Chapter 4-8 use tools
from Compass, Synopsys, Actel, Altera, and Xilinx. The examples in Chapter
9 (covering low-level design entry) used tools from Exemplar, MINC, AMD,
UC Berkeley, Compass, Capilano, Mentor Graphics Corporation, and Cadence
Design Systems. The VHDL examples in Chapter 10 (VHDL) were checked using
QuickVHDL from Mentor, VSystem Plus from Model Technology, and Scout from
Compass. The Verilog examples in Chapter 11 were checked using Verilog-XL
from Cadence, VSystem Plus, and VeriWell from Wellspring Solutions. The
logic synthesis examples in Chapter 12 were checked with the ASIC Synthesizer
product family from Compass and tools from Mentor, Synopsys, and UC Berkeley.
The simulation examples in Chapter 13 were checked with QuickVHDL, V-System/Plus,
PSpice, Verilog-XL, DesignWorks from Capilano Computing, CompassSim, QSim,
MixSim, and HSPICE. The test examples in Chapter 14 were checked using test
software from Compass, Cadence, Mentor, Synopsys and Capilano's DesignWorks.
The physical design examples in Chapters 15-17 were generated and tested
using Preview, Gate Ensemble, and Cell Ensemble (Cadence) as well as ChipPlanner,
ChipCompiler, and PathFinder (Compass). All these tools are installed at
the University of Hawaii.</P>
<P><A NAME="anchor327676"></A>I wrote the text using FrameMaker. This allows
me to project the text and figures using an LCD screen and an overhead projector.
I used a succession of Apple Macintosh computers: a PowerBook 145, a 520,
and lastly a 3400 with 144 MB of RAM, which made it possible for me to create
updates to the index in just under one minute. Equations are "live"
in FrameMaker. Thus,</P>
<P ALIGN="CENTER"> book thickness = #pages x 0.0015 in./page = (1000) (1.5 x 10<SUP>– 3</SUP>) = 1.5 in.</P>
<P>can be updated in a lecture and the new result displayed. The circuit
layouts are color EPS files with enhanced black and white PICT previews
created using L-Edit from Tanner Research. All of the Verilog and VHDL code
examples, compiler and simulation input/output, and the layout CIF that
were used in the final version are included as conditional (hidden) text
in the FrameMaker document, which is approximately 200 MB and just over
6,000 pages (my original source material spans fourteen 560 MB optical disks).
Software can operate on the hidden text, allowing, for example, a choice
of simulators to run the HDL code live in class. I converted draft versions
of the VHDL and Verilog LRMs and related standards to FrameMaker and built
hypertext links to my text, but copyright problems will have to be solved
before this type of material may be published. I drew all the figures using
FreeHand. They are "layered" allowing complex drawings to be built-up
slowly or animated by turning layers on or off. This is difficult to utilize
in book form, but can be done live in the classroom.</P>
<P>A course based on FPGAs can use Chapter 1 and Chapters 4-8. A course
using commercial semicustom ASIC design tools may use Chapters 1-2 or Chapters
1-3 and then skip to Chapter 9 if you use schematic entry, Chapter 10 (if
you use VHDL), or Chapter 11 (if you use Verilog) together with Chapter
12. All classes can use Chapters 13 and 14. FPGA-based classes may skim
Chapters 15-17, but classes in semicustom design should cover these chapters.
The chapter dependencies — Y (X) means Chapter Y depends on X — are
approximately: 1, 2(1), 3(2), 4(2), 5(4), 6(5), 7(6), 8(7), 9(2), 10(2),
11(2), 12(10 or 11), 13(2), 14(13), 15(2), 16(15), 17(16).</P>
<P>I used the following references to help me with the orthography of complex
terms, style, and punctuation while writing: Merriam-Webster's Collegiate
Dictionary, 10th edition, 1996, Springfield, MA: Merriam-Webster, ISBN 0-87779-709-9,
PE1628.M36; The Chicago Manual of Style, 14th edition, Chicago: University
of Chicago Press, 1993, ISBN 0-226-10389-7, Z253.U69; and Merriam-Webster's
Standard American Style Manual, 1985, Springfield, MA: Merriam-Webster,
ISBN 0-87779-133-3, PN147.W36. A particularly helpful book on technical
writing is BUGS in Writing by Lyn Dupré, 1995, Reading, MA: Addison-Wesley,
ISBN 0-201-60019-6, PE1408.D85 (this book grew from Lyn Dupré's unpublished
work, Style SomeX, which I used).</P>
<P>The bibliography at the end of each chapter provides alternative sources
if you cannot find what you are looking for. I have included the International
Standard Book Number (ISBN) and Library of Congress (LOC) Call Number for
books, and the International Standard Serial Number (ISSN) for journals
(see the LOC information system, LOCIS, at http://www.loc.gov). I did not
include references to material that I could not find myself (except where
I have noted in the case of new or as yet unpublished books). The electronic
references given in this text have (a last) access date of 4/19/97 and omit
enclosing <> if the reference does not include spaces.</P>
