In my office, the dongle can't be found by the USERS! In the last few years,
81% of the staff in my lab was laid off, and their corporate 'last remains'
occupy 40 or so cardboard boxes. No dongle in there. Luckily, I only use
the PC version for Xchecker, which doesn't require the dongle. I use
the Sun version of the compilers, but I have a useless CD of the Windows
software because upgrades assume that you haven't lost the dongle.

			FPGA `96 Advance Program

1996 ACM/SIGDA Fourth International Symposium on Field-Programmable Gate Arrays

			     February 11-13, 1996
		Monterey Beach Hotel, Monterey, California, USA

Sponsored by ACM SIGDA, and Xilinx, Inc., Altera Corp. and Actel Corp.

Over the past ten years FPGAs have revolutionized the way many systems are 
designed by providing a low-cost, fast-turnaround implementation alternative. 
This is an exciting time in an exciting field that is still expanding as new 
technologies appear, new architectures are proposed, and new CAD tools are 
developed to address problems specific to FPGAs. This Symposium focuses on the 
architectural and algorithmic issues that FPGA architects and CAD designers 
face today and in the future. This is a forum where researchers from industry 
and university present and debate the latest ideas in FPGA design and 

The technical program consists of papers concerning both the practical 
and theoretical aspects of FPGA architecture, CAD algorithms for using 
and testing FPGAs, and applications. The Symposium will be of interest 
to those developing FPGA architectures, both at the chip and board level, 
and those developing CAD algorithms for FPGAs. The Symposium is not of direct 
interest to immediate users of FPGAs.

	     FPGAs vs. Gate Arrays and Processors: Who Will Win?

The FPGA industry has enjoyed rapid growth in the past ten 
years in terms of chip density and speed as well as ASIC 
market share. In the same period, however, we have also 
observed significant advances in all sectors of the semi-
conductor industry -- state-of-the-art gate arrays have a 
capacity of over 10 million transistors and enable the 
`system-on-a-chip'. Design automation tools have made 
semi-custom designs much faster and easier to achieve while 
yielding both high density and high performance. High-end 
microprocessors have reached over 250 Mhz and can satisfy 
the needs of many real-time control and DSP/multi-media 
applications. New rapid prototyping technologies, such as 
laser-programmed gate arrays, have emerged for high-speed 
high-density prototyping.

Given such a dynamic industry undergoing exponential 
growth, it is interesting to ask where FPGAs will stand five 
or ten years from now in the wide spectrum of design 
technologies. Will its share of the ASIC market continue to 
increase, or will it become more of a niche technology? It is 
likely that the relative importance of these technologies will 
change drastically over the next five to ten years.

This panel comprises technology experts in the competing 
areas of FPGAs, gate arrays, processors and other 
technologies. They will focus on the technological and 
economic issues that give one implementation medium an 
advantage over others and discuss how new technologies and 
architectural developments may change the competitive 
balance. They will discuss the past, present and future of the 
technological forces driving the industry and debate where 
those forces are likely to take us in the future.

The Xilinx timing and simulation models are for:

Voltage:  5 volts +5% for commercial grade
          5 volts +10% for industrial and military grade

Temperature:  +85C junction temperature for commercial grade
              +100C junction temperature for industrial grade
              +125C case temperature for military grade

Output Loading:  50 pF

The models are worst-case.  The only known discrepancies are in the
setup time to input flip-flops and clock-to-output timing from
output flip-flops.  The simulator is overly pessimistic in some
cases.  Xilinx specifies guaranteed pin-to-pin values for I/O setup,
hold, and clock-to-output times in our data sheets.  These should
be used instead of the pessimistic simulation values.  We are correcting
this problem in a future release of the software.

We have the FLEX-700 here (it's pretty much the same as the 700B, except that it 
has a special I/O card instead of a parallel port interface). I've been using it
for almost 2 years now for PLDs, CPLDs, and micros and it's worked fine. I've 
talked to their tech support a couple of times and have downloaded a half dozen new 
device files from their BBS.

I notice that you left out the Logical Devices series of programmers... Any reason
in particular? I have a ChipMaster 3000 at home, and I feel like I've been 
"dead-ended" by Logical on this. I wanted support for the Atmel 89C2051. The response
I got from the salesperson was that the ChipMaster 3000 was no longer supported (so
much for lifetime -- I guess the product's lifetime -- S/W support by BBS). He
then tried to give me a great "deal" on their "new" programmer if I traded in my
ChipMaster 3000. No thanks... I was burned once, I'm not going to get burned again...

If I had to do it over again, I'd buy the FLEX-700.

Hmmm, Interesting, I run windows 95 and have the Needhams EMP20
that runs perfectly fine under Windows.  Are you using the internal
unit or an EMP20?  If external, do you have a printer configured
to use the same port?

I have used the programmer for 8751, 8752, all type of Eproms, MACH
parts and some gals so far. It works well.  Same gripe though
about not being a windows app.

Right; one of the tricky things with device programmers is figuring out
how to code all the options a chip might have.  I've seen many programmers,
for example, which do not support the 8x51's useless "code encryption" array
[no big loss since the security on that is nearly worthless, but it would be
nice to have it supported].

I think the biggest concern manufaturers have is the possibility that some-
one will program a part with a lousy programmer and then blaim the part
manufacturer if the part is unreliable.  Personally I like Microchip's
"take" on this issue: they make it really easy to produce development
programmers but explicitly state that for reliable operation certain extra
steps [verify at Vmax and Vmin] are needed.  My only complaint with their
policy in this case is that they don't state what level of verification is
needed if a part will only be used at, e.g., 5.00-5.05 volts.

BTW, one problem I have with a lot of programmers is that manufacturers
tend to bundle EVERYTHING of the programmer software into one file.  This
means that if I want to download the upgrate so I can program one new chip
I have to download a HUGE file.  It would be nicer in many ways if the
devices could be divided up by category so as to allow a user to download
only those files he needed.

BTW, I use a BP programmer at work and I was wondering: [1] Is there any
convenient way to wire a harness and use it for in-circuit programming PICs?
[2] What testing does the programmer perform on PICs?  Since programming uses
only a subset of the pins on the device, does the BP do any testing on the
other pins?  It might be useful if BP supplied test code for different micros
and test vectors so that the programmer could verify that the chips were
fully operational [I've blown port bins on occasion] :-(

Can someone shed some light on the following question:

What temperature/supply voltage conditions does the simulator 
simulate a design for? And,generally, what degree of confidence about 
the FPGA's functionality at various temperatures/supply voltages can 
a designer get by using the simulator (running the timing simulation 
on a "tied" .lca file)?

I see that someone else has my problem.   Due to the lack of finance I am only able 
to teach 20 on-campus students how to design using FPGAs.   I need a sub-set of the 
Xilinx 2064 or 3020 so as to post them to hundreds of off-campus students who 
are using a 386 or better.  

Rowland Hill introduced the postage stamp so that the average person could afford to 
send letters.   Look at the postal industry today.

How about some cheap, student introductory versions able to be purchased with a text 
book similar to MicroLogic etc.

I am one of the founders of NeoCAD, and I am now at Xilinx.
I would like to thank those who have had kind words for NeoCAD on
this forum, and I want to clear up some misconceptions about AT&T
and the Xilinx acquisition of NeoCAD.

AT&T recruited the NeoCAD technical staff heavily, and wound up hiring
only four engineers from NeoCAD.  They are excellent engineers, wonderful
people, and we miss them and wish them well.  However, they do not
comprise a "good chunk of the core development team."  In fact, the
entire technical management staff and all of the lead engineers
are at Xilinx (about 30 NeoCAD engineers and engineering managers).
We have also hired replacements for the people who left, and it so
happens that they, too, are excellent engineers and wonderful people.

The Xilinx and NeoCAD software groups have merged into one team,
and we are hard at work combining the best technologies from both
companies into a single product, including support for a variety
of new FPGA families.

Subject: Re: XBLOX: the good, the bad and the shocking
From: (Gerhard Hoffmann)
Date: 23 Nov 1995 05:22:24 GMT
Links: << >>  << T >>  << A >>
Somebody asked for XBLOX experiences last week. 
Here are mine:

I'm a consultant / free lance designer and just completing 
a chip that barely fits into a 4010. It's a spread spectrum 
controller and its main ingredients are counters of all fla-
vours.  The Chip runs from a 40/20 MHz clock.

This obviously calls for the use of XBLOX. There are
about 40 XBLOX devices, including a few bus slices etc.
that don't generate hardware.

I made the following observations:

I needed a clock divider by 20 million ( 20 MHz to 1 Hz )
with 1:1 duty cycle. Not much to it:
Input pad  -- clk_div -- output pad.
XBLOX crashed the PC.

Scared by my exaggerated expectations i then tried a
divider by 2000. XBLOX survived the synthesis but the 
generated clk_div divided by something like 2800.

Dividers by 200 and smaller seemed to work, as well as
a divider by 10000. I cascaded several of them and played
games with the count enable inputs, so i could still
have everything synchronous with the global 20 MHz clock.

This changed the timing, of course. I had to add pipeline 
stages in the surrounding circuit to make up for the extra

The complexity of the whole thing has increased from a single
symbol to a sheet. Building it from msi-like macros would
have probably been less mess, even without fast carry logic.

The story is not at its end, however.

Recently we decided that it would be a good idea to synchronize
this divider with some other stuff. Looks simple. Isn't.

The manual says: When the SYNC_CTRL input is high, the clock
divider is reset to the beginning of the duty cycle.

If i drive both EN and SYNC_CTRL high for one clock cycle, the
divider happily keeps counting - and it shouldn't.

I spent most of this day with XACT and a HP16500 to investigate
what's going on and what hardware has been generated.
I don't think it's my job to reverse engineer my own chips.

I think it's a negative effect of systems like XBLOX 
that you are effectively locked into one single vendor.
In addition you loose knowledge about the implementation of
your design. You have to trust your tool vendor and cannot
prove parts of your design. Throw lots of test vectors
at the problem and your design will probably simulate ok;
but can you choose the right vectors if you know nothing
about the innards of the black box?

I told our local XILINX representative ( Metronik) about the
crash and the wrong divide ratios already half a year ago, when
5.1 came out. The FAE found it funny and remarkable. Maybe he 
relayed it to XILINX, but i never got any response at all.

I didn't find them helpful with other problems, too. 4XMPL:

The (now probably outdated) diskette installation software
crashed when the video mode number was != 3 (on PC under MessDos).
Was i really the first one to discover that a 20" monitor can
display more than 25*80 chars?
(I had Vmode=100, 40*100 with a nice font on most ET4000* cards)

The current CD-rom installation program cannot find one of it's
files if you have Microsoft share loaded. Given the time that
i finally got my 5.1 CD-Rom (after complaining), a few hundred
people with local networks must have already stumbled over this.
Should everybody reinvent the wheel?

I think that this newsgroup could be most valuable to publish
such findings.

Another thing:
I once had a simulator named SILOS from Simucad ( with a quite
offensive user interface). XILINX don't support it any more.
The current version, SILOS III, seems to be pretty and
accepts Verilog input, too. 

Does anybody know of a supplier of an XNF -> Verilog converter
that runs on PC?

Metronik proposed buying Cadence; (or VHDL would be even better).
No thank you; it's my own money and i have esthetic problems
with VHDL. And I watched others using it.

A product for the opposite direction (Verilog -> XNF) would be
interesting, too. Now, that the Pentium Pro is approaching
it's probably a bad time to change to a workstation.

The aim of this workshop is to bring together workers from throughout
the world for a wide ranging discussion of all forms of field
programmable logic (but particularly field programmable gate arrays)
and their applications. It is intended to discuss the increasing range
of device types, industrial applications, advanced CAD developments,
research applications, novel systems architectures and educational
experiences. The workshop will include regular presentations, posters
and discussion sessions and it is expected that most of the delegates
will wish to make some contribution to one or more of these. The
workshop is to be considered as continuation of four already heldSE
international workshops in Oxford (1991 and 1993), Vienna (1992) and
Prague (1994).


Contributions are invited for regular presentation, poster and
discussion sessions. Prospective authors are invited to submit an
abstract of at least 500 words or a full paper by 6 March 1996 to the
Program Chairman. Please preface this by your full correspondence
address, including e-mail, and fax, a list of (at most) 5 one-line
statements that best encapsulate the essence of your proposed
contribution, and a note of your preferred presentation format. Please
mail 10 copies if possible, but submissions by e-mail
( or fax (+49 631 205-2640) will also be
NOTIFICATION OF ACCEPTANCE will be posted by 8 May 1996 and final
papers must be received by 3 July 1996 to guarantee distribution at
the workshop. Accepted papers will be published in book form by
Springer before the workshop. Potential exhibitors and tutorial
presenters are also invited to contact the Program Chairman. The
official conference language as well as the language of submissions
and accepted papers will be English.


Field Programmable Logic has been available for a number of years, but
the increasing power and variety of devices now available is extending
its role from that of simply being a convenient way of implementing
the system glue logic to an increasing ability to implement mainstream
system functions. The speed with which devices can be programmed makes
them ideal for prototyping and education, the reprogrammable devices
are opening up sophisticated new applications and hardware/software
trade-offs. CAD is developed for automatic compilation of advanced
designs and routes to custom circuits are now available.


The topics should cover, but are not restricted to:
  - New and future commercial devices 
  - Novel chip architectures
  - New software and hardware development tools 
  - Bridges to other CAD and to custom circuits 
  - High-level design and compilation research
  - Industrial applications and experiences 
  - Trade-offs betweendevices, architectures and technologies; 
	   Benchmark comparisons
  - Smartapplications 
  - Custom computers 
  - Hardware/Software Co-Designusing FPL 
  - Novel machine paradigms and system architectures
  - ASIC emulators, hardware modellers and compiled accelerators
  - Fault models, testability methods, reliability
  - Educationalexperiences and opportunities

   Take a look at Exemplar. They have platforms that run on PC (as well as UNIX). 
Depending on the particular FPGA technology your targeting, they support various vendors 
with specific optimization algorithm's (and they support most of the popular FPGA/CPLD 
vendors ie: Xilinx, AT&T, Altera ... etc.).

No it does not.  That is if you don't care about how big these cells
are and how long they take to program.  If you really need just a few
bits (the suggested public key memory would need a few hundred), it is
possible to come up with an EPROM or even EEPROM cell in standard

What you really want to do is check out the on-chip Xilinx RAM.
We have a technical report on this and other synthesis issues at

Hope this helps,

None of these so called simulators come close to what is reality unless the circuit under test 
is put into a cold chamber where you can control the temperature to few tenth of a degree!!

shouldn't that be 5V MINUS 5 or 10 percent?

Here is a Xilinx XNF netlister which we use to extract netlists
from NTK files as generated by diglog (Chipmunk).

I also included some sample designs that run on the Xilinx 3K/4K
demo board.

You will still need to have access to the Xilinx core FPGA tools.
The entry level pacakage of just the core tools which can target
the smaller Xilinx chips (up to 3042 and 4003) is available for
$1000 from several chip suppliers. Chipmunk and this pacakage is
probably the cheapest way to thet into Xilinx FPGAs.

See ya, -ingo

Why was I told by Logical Device's sales department that the Chipmaster 3000
is no longer being supported??? (That was the reason I was given for Logical
Device's lack of ATMEL 89C2051 support).

Ok, I'll respond to my own post here... It seems that the CM3000 is still
supported (why was I told 6 months ago that is wasn't??? and that I should
trade in my CM3000 towards a new programmer??? -- actually -- I was FAXED
this information, so at least I know I'm wasn't hearing things...), and
that they now
have 89C2051 support.

I always assumed that the longest net delays ("worst-case") are exhibited at 
highest temperature and _lowest_ supply voltage (not the highest one). Was I 
wrong in that?

I placed the instructions and a basic program to program the Atmel
17Cxxx FPGA Configuration EEPROMs on a PC parallel port in our ftp

It's pretty straight forward and we have used it to program config.
proms for Xilinx chips on one of our robots...
