PROGRAM

August 14, 1994

Tutorial Schedule:

7:30-8:30     Registration & Coffee at Memorial Auditorium

8:30-12:00    Algorithms & Hardware for Video Compression

12:00-1:00    Lunch

4:30-6:00     Wine & Cheese Reception in the Dohrman Grove
              Just North of the Hoover Tower on Serra Street


Tutorial 1:   Algorithms & Hardware for Video Compression
              Teresa Meng, Stanford University

This tutorial will give an overview of the industry standards for video
compression, including compression algorithms, performance comparisons
and hardware implementations. Fast algorithms to achieve real-time
encoding and decoding will be one focus of this tutorial. Besides
industry standards, recent developments in compression techniuqes, such
as subband and wavelet filtering and vector quantization will be
covered. Finally research activities in the area of low-power
implementations for portable video applications will be surveyed.


Tutorial 2:   Instruction-Set Extensions for Multiprocessor Interconnects
              David James, Apple Computer

Most instruction sets have been optimized for uniprocessor
environments. To effectively utilize multiprocessors on scalable
interconnects, processors need to support additional capabilities,
including 64-bit addressing, a well-defined set of memory access
capabilities (loads, stores, and locks), non-blocking interrupts and
synchronized time-of-day clocks. As background, the constraints of a
typical high-speed interconnect, ANSI/IEEE Std 1596-1992 Scalable
Coherent Interface (SCI), are considered. We show that specialized
signals (such as bus-lock and interrupt) as well as eavesdrop or
broadcast-based protocols can be avoided, explicit lock instructions
(such as fetch&add) scale better than LoadReserved- and
StoreConditional-based instruction sequences, and mixed endian data
types (big and little) require minimal hardware (but significant
compiler) support. We show how these conditions impact the design of
processor instruction-set extensions.

One Day Xilinx Summer Workshop 
"Field Programmable Gate Arrays in the Classroom"

Workshop 1   (Viewlogic Based)
Date:  	   Friday, August 12
Location:  Painter 3.20 (Dell Lab)
           University of Texas at Austin
	   Austin, Texas

Workshop 2   (Mentor Based)
Date:	   Monday, August 15
Location:  University of Notre Dame
	   Notre Dame, Indiana

Workshop 3   (Mentor Based)
Date:	   Thursday, August 18
Location:  Colorado State University
	   Fort Collins, Colorado


The Xilinx University Program will be holding several 
regional one-day "hands-on" workshops in August to 
introduce university faculty, staff, and graduate
students to Field Programmable Gate Arrays as a learning 
tool in Digital Design courses.  The goal of the workshop 
is to provide the information and assistance necessary to 
develop and conduct or enhance undergraduate courses in 
Digital Design using FPGAs.  This intensive one day 
workshop will allow a forum for gathering information and 
provide first hand experience with industry CAE and FPGA 
implementation tools.  The hands-on labs are structured 
so the students will perform the entire design flow and 
see it working in a prototyping board. 

FPGAs are not just for Digital Design courses.  Many 
universities have utilized the technology for courses 
in computer architecture, senior research projects, VLSI 
design, and ASIC design.  The flexibility of the 
architecture, reprogrammability of the devices, and the 
simplicity of the design tools makes Xilinx FPGAs ideal 
for the university environment.  An instructor can guide 
their students through an entire design entry, implementation, 
and simulation process and download results directly into 
silicon on the desktop.  New features in the XACT 5.0 software
will be covered.  

The workshops will be free of charge.  A complimentary 
continental breakfast and lunch will be served on premises. 

An information packet will be sent to you by Stacey Pinckert
of Xilinx.  The packet will include directions to the university 
and a list of lodges in the area.  Applications are due two days 
before the workshop date.

Subject: inexpensive FPGA prototyping
From: devb@char.vnet.net (David Van den Bout)
Date: 29 Jul 1994 20:08:36 -0400
Links: << >>  << T >>  << A >>
Since some body asked, I'll respond.  We are offering
a new book which teaches digital logic design using the Intel/Altera
FLEXlogic FPGA.  The book shows how to build
a FPGA prototyping board for about $100 and then uses the board
to build combinatorial logic, state machines, and a 4-bit
microcomputer.  A completely-assembled 4'' x 2'' circuit board
is also available for those who want to get started quickly.
Several of these boards can be concatenated to build multi-FPGA systems.
The book and board use the Intel PLDshell software for programming,
and PLDshell is available free from Intel either as floppy disks or
from several FTP sites.
  
For a more complete description of these products, send e-mail
to devb@vnet.net with the subject line of "fpga".

We must have trained them!  We begged for an internet address & we
were refused!  There were a few issues regarding the iFX780 which the
phoneline tech support people hadn't been briefed at all.

Glad your experience was a better one.  After we got the problems
worked out they have worked very good.

Subject: Xilinx File formats
From: wheelerd@clark.net (David E. Wheeler Jr.)
Date: 29 Jul 1994 20:39:24 -0400
Links: << >>  << T >>  << A >>

I'm interested in finding descriptions of the file formats used by
Xilinx and NEOCad.  Are these published anywhere?  Has anyone
reverse-engineered them?

The reason I ask is that the company I work for uses Xilinx parts a
lot but the placement and routing is a major bottleneck in the design
process.  I'd like to experiment with some placement and routing
methods of my own but I need to read these files to do it.

Thanks,

Subject: How pricey is FPGA development?

Hi,

Just how expensive is FPGA development? Is it at all possible for an individual
to purchase the necessary software/hardware to use high density devices for
example at a reasonable cost?

I have looked at some vendors such as Lattice and Intel. The Intel SW
is quite nice as it allows device independent design, something which the
Lattice pLSi sw doesn't seem to do. However these vendors seem to be making a
good effort to get their products into the hands of individuals at a reasonable
cost.

Do I really need to purchase several hundred pounds worth of software to even
consider looking at the high density FPGAs? A simple functional design tool
would suit me fine, it doesn't have to be fast or Windows based.

Any advice appreciated.

Best Regards,


Roger

Hmm... I remember about ~12 years ago I would get Fortran source code
for Palasm from MMI; thats right, joe user had to compile the stuff
himself - I even added a few routines to create nroff data
sheets that would become 'unix-like' man pages. Those were the
days...

Now we have companies like Xilinx, Actel, etc; these guys are really
software companies - Xilinx and Actel will even tell you so if you have
the chance to talk to some of there high level engineering folks.

I wonder why the PC based tools are cheaper than the Unix tools.
In the past the argument was that Unix was multi-tasking, therefore
you could 'do more' than with a PC running DOS. Five years ago with
the home brew Unix license mechanisms of these vendors this was true;
today with Highland Digital you can restrict all the way down to a
single task per node. What gives?

I don't think that this is true. All my intermediate files are ASCII.
I can't even find a "convert to binary" converter.  I'm using XACT 5.0.

  OTC  07/12 1622  Altera to acquire Intel programmable  logic business

SAN JOSE, CALIF. (JULY 12) BUSINESS WIRE - July 12, 1994--Altera Corp.
(NASDAQ:ALTR) announced Tuesday that it will acquire Intel Corp.'s
programmable logic business for a price of approximately $50 million.
   The purchase price consists of $25 million in cash and 779,277 shares of
Altera common stock, subject to certain post-closing adjustments.  The
transaction is expected to be completed on Oct. 1, subject to governmental
approval.  Immediately after the closing, Robert Reed, senior vice
president and general manager of Intel's Semiconductor Products Group, is
expected to join Altera's board of directors.
   The relationship between the two companies dates back to 1984 when
Altera licensed Intel to Altera's first family of products in exchange for
process technology and wafer manufacturing services.
   "Intel is the premier semiconductor company in the world.  Our
partnership with Intel played a significant role in Altera's early
development and we look forward to continuing our relationship with Bob
Reed on our board of directors, " said Rodney Smith, president, chief
executive officer, and chairman of Altera Corp.
   As part of the sale, Altera will receive Intel PLD products and licenses
to use associated process technologies and intellectual property to build
PLD products.  In addition, Intel agrees to supply wafers to Altera in
support of the business.
   "Altera is a recognized leader in the programmable logic market. Intel's
investment in Altera allows Intel to share in the continued growth and
development of the PLD market and to realize the best possible return on
its prior investment in this business.  I will work actively with Altera to
ensure a smooth transition for Intel customers," according to Reed of
Intel.  The two companies are each planning to prepare customers for the
transition of the products to Altera by Oct. 1.
   Employee transfers are not included in the transaction. However, Altera,
at its discretion, may make employment offers to any of Intel's current PLD
employees.
   Altera pioneered the high density PLD market which remains one of
today's fastest growing semiconductor areas.  The addition of the Intel
products complements Altera's broad range of programmable logic solutions.
Software support will continue to be provided by Altera through Intel's
PLDshell product and will be added into Altera's MAX+PLUS II software in
the future.
   The Intel product line consists of 15 devices ranging from the popular
22V10 to the recently introduced FLEXlogic line.  FLEXlogic contains
several unique features compared to other high density programmable logic
devices on the market and complements Altera's industry leading MAX 7000
and FLEX 8000 families.

Yeah.  I heard through the grapevine that it may take up to
a day to coplete a compilation of Xilinx designs before you
can program silicon.  But of course this is unconfirmed hearsay
and I have not worked w/ the Xilinx design tools.

I have heard about NeoCad.  I thought it was only a design
capture and sim tool.  Does it compile designs for target
FPGAs as well?

I don't agree. These software products look great on the marketing
man's papers, but when you really start doing something you'll
notice that the tools do just about the minimum, what they have to.

Well, some people like to say that a SW product is never ready.

And these companies do get their bread from the HW...

I have been using Xilinx and ppr for about two years.  I have not used
any other competing programs, so have no other point of reference.

The compilation time of ppr depends very much on how far you are pushing
the technology, both in how much of the Xilinx device is being used, and
in your speed requirements.

I have used devices ranging from a 4005 to a 4010.  I run ppr on a 
SparcStation IPX with clock-doubled CPU.

For any of the devices, with up to about 70% utilization of function
generators (I tend to use them up first) and about 60% utilization of
flip flops, I see from 10 to 15 minutes of ppr time for one run.  If
you use the path timing capability of ppr (where you can place an
upper limit on the time from a flop's output to another flop's input,
the time can go up by a factor of three or four.  I've tried path timing
only once and found it very lacking compared to my usual approach of
flagging critical nodes and doing hand placement of flops for time
critical portions of the circuit.

I have found that if I go over about 75% utilization of function
generators, ppr has real problems.  I suspect that it is because my
circuits don't always fit cleanly into the Xilinx model of four inputs
feeding each flop, so the actual resource utilization is much more
than 70%.  Occasionally ppr will take a long time (30 minutes instead
of 10 minutes) when it does a really poor placement.

My really time-critical circuits meet the four-input constraint for
all time critical flops, and I have completely hand-placed a couple of
4006's to get things to run fast enough.  ppr didn't have a chance
of meeting my timing requirements without this.

All of this is to say that "up to a day" is, in my experience, not
close to the truth.  Of course, if you need 100 runs to get one with
good enough timing, it can easily take a day.  Also, getting the
first one through the tool set will take a while, just to learn how
the tools work.

I need large net lists for a current study of cpld/fpga/asic
design. 10K gates/1000clb/1000le/1000modules would be fine,
100K gates even better. Edif/xnf/verilog/vhdl is ok.
Does anyone know of such a database
(or have any to donate).  I don't need the functional 
specification, I am only interested in the geometric structure.

I already know about mcnc, so no need to reference them.

Thanks for your help

We have developed some (in house) layout tools that are timing
driven and do great job when compared with Xilinx tools for some
of the MCNC and other benchmark examples. I am interested in getting
some design examples with timing constraints that are desired. 
Currently we do routing using our own fast multi-terminal router but 
that is going thru changes. The placement part is fully automated.
Correct lca files are generated to perform routing using Xilinx router(s).

Anybody willing to share design examples (nda no problem) would help 
us a lot!!

Hi all,


How does XACT5.0 compare to XACT 4.03? I have used xact 4.03 and don't 
think much of it, espcially the xblox library.

Has the routing become more predictable?
have they allowed the designer more access to routing resources?
Are there any *TRUE* incremental routing utils in XACT 5.0?
Can we generate "hard macros" in xact 5.0?
can we route a functional-block of arbitrary fix it in that position in
subsequent routing ?

your views would be appreciated

Ahmed...

Not to be grumpy or anything :-), but if they got their bread from their
hardware, one would expect them to be enthusiastically handing out free
copies of the software to promote hardware sales.  Nothing could be
farther from the truth...

Just to add another data point, I have been using Xilinx ppr tool for
about a year. My target devices are 4010 parts, with a utilization of
50-60%. However, my place and route times are on the order of 2-3 hours
using a sparcstation 10.

Some of the things which are no doubt causing added processing are:

1) The abundant use of path timing constraints, some of which are
tight.
2) The use of several hard counter macros (which obstruct routing).
3) The use of several 16 and 32-bit busses (which require lots of
routing).
4) Setting place and route effort levels fairly high to get good
timing.

Has anyone tried ever to create a pierce x-tal oscillator using I/O pins
from a FPGA (I'm thinking here about the intel 780)?
I would need this for a slowish (<10MHz) oscillator on a single-chip
solution using the FPGA.

Any luck, or should I use an external oscillator?

The key to getting the s/w free is to dangle a large enough quantity
of parts to be sold in front of the Rep/Disti/Dude.  Most of these
companies want to sell 10,000 or 100,000 parts and are willing to hose
the smaller companies/individuals and only hand out freebies where
they think they can get business.  Otherwise software is just another
profit center :-(

In a sense this is similar to NRE costs on ASICs - you can pay now, or
make it up in volumes later.

I would love to see all of the FPGA guys come out with a bare-bones
product for free - no auto place & route, no support, just a disk -
take netlist in, spit timing out, and maybe an interface to a
simulator and a bitstream for the part.  That would keep the 'freebie'
people happy, and save the real effort for the paying customers.

From: hadlich@csmd.cs.TU-Magdeburg.DE (Thomas Hadlich)
Date: 4 Aug 1994 06:57:25 GMT
Links: << >>  << T >>  << A >>
Hello,

I'm having problems with my mouse when I start MAKEBITS from XDE. Somehow
the program recognizes my mouse as a XCHECKER cable. Thus I can't use my 
mouse. I already tryed the 'port' command, and to save a proper configu-
ration in the profile, but that doesn't help.
Somehow the problem can be fought by moving the mouse when starting 
MAKEBITS. But that works only in 2 of 3 cases. And I feel really stupid
jerking around while starting a program.. :)


I'm not quite sure if this is the right place to ask, but I know no
better place..

If you can help me please answer by pm.

Thank you
   
   Thomas Hadlich
