I think it is a better option to not only share the license, but also
share the machine it is running on. You could have a mail interface for
script based synthesis. Customers send in a mail with their HDL and a
synthesis script along with a target technology. It runs on the idle
computer with the idle license and returns a netlist by mail. This way
you would factually be running a design house with specifications
written down in hdl and a script, and who could object to that ?
I think there would be a great market for this, since there are many
small businessis that can not afford a full license for say Synopsys
Design Compiler.
Best regards,
Peter

As did I.  And sometimes, when I'm forced to enter the Unix domain and
use one of those editors, I realize that I can write an entire 12-page
document with diagrams and color pictures using Microsoft Word in the
time it takes me to remember what the proper key combination is to exit
and save a text file from a Unix editor. 
And give me Word any day over trying to hack runoff or LaTex.

  A visual C++ development environment is much better than any Unix
environment I've ever used.  The visual C++ debugger is quite pleasant.
Integrated object browsers, documentation, and resource editors make
it almost too easy to develop (windows-based) software.  I've struggled
with Unix debuggers, but never found them easier to use than just putting
printf's in my code.

Evolution?  I agree that Unix has an admirable history.  Once upon a time
it was the best thing around (well except for VMS :)  It is especially 
loved by people who like to develop more Unix tools and gadgets.  But
for doing other work, Windows is simply more useful.  While Unix has
thousands of hackers controlling its evolution, Windows has millions
of customers and billions of dollars.  It has the support of office
users, game players, scientific users, hardware developers, multimedia
developers, and millions of software developers, too.  I agree that
evolution applies here, but it looks to me that natural selection
favors Windows.  I don't like this any more than you do, but I've
accepted it.

I haven't seen this.  Do you have an example?  Are they porting GNU tools
to windows because it's a fun game, or are they really using it to develop
application software.

Sometimes I have to document my work.  :)
Usually I use them to analyze scientific data.
I have a chip floorplanner that runs under microsoft Excel, although
you'd be happy to hear that it also uses ~1000 lines of AWK code.

For IEEE and ACM conferences, you should contact IEEE and ACM directly.  I 
know that the FPGA and FCCM proceedings are available that way.  For FPL you 
can contact Springer and Abingdon (the publishers).  The pattern for FPL seems 
to be that the England offerings are published by Abingdon, the non-England 
ones by Springer (however, several of my proceedings are on loan so I couldn't 
check).

For RAW, I'd try the program committee chair.  If it has a professional 
organization that it is associated with, you can contact them directly.

Hello Everybody,
We got a SPARC Workstation from a bankrupt client of us. By
coincidence we found out, that this workstation was used as a file and
license server for Synopsys tools.
We don't know what this is worth, but that company owed us
160.000,--DM (~US$90.000,--) so we would like to sell this
workstation. The best offer will get it.
The license server has several licenses for the following Ver. 1999
packages:
	dc_expert ultra plus
	test compiler
	bahaviour, verilog, vhdl compiler
	prime time
	designware developer ultra
	FPGA compiler II
	etc.

If someone is interested in this workstation please email me.

Things aren't standing still in Linux etc. Currently I, too, still prefer MS
VC/Word etc.
But looking at code crusader (like MS DevStudio) /word perfect (Word) /gdb
gui etc may soon change your opinion.
Cygnus are putting together some nice Linux development tools.

As a s/w engineer on the side its better to have dev tools that run in more
places.
Certainly the user support/ bug fixes / additions are considerably better.

Anyway at present its keeping Microsoft on their toes, which has got to be
good for users everywhere.

Who knows in five years they might go the way of IBM. (ie not quite so
dominant but still a force)

Enough jabbering. This is off-topic.

I want to be able to run my FPGA tools on whichever machine I have handy!

I would suspect that you could do exactly what you are suggesting (assuming 
you don't need something so fast that you need prescaled counters, etc.).  
I'll assume you are building just an up counter, though an up/down counter may 
be doable, but slower.

Build a counter large enough to hold the entire range of values.  The counter 
would essentially be an adder with an output register "count" that feeds back 
to one input, plus a register "increment" that says how much to add to the 
value at each step.  Also, a seperate exponent logic would be needed, which 
would be a basic integer upcounter.  The counter is initialized to the proper 
initial bit pattern for the starting mantissa and exponent.  We also load the 
increment counter with the proper value for the stride, assuming that it has 
exactly the same exponent as the count number (thus, if the counter starts at 
10010.0101, and you want to increment by 1 each time, you would set the 
increment value to 000010000, so that the 1 lines up with the proper bit 
position of the counter value).

Now, if for each upcount you add the increment to the counter, everything 
works fine until you overflow the mantissa.  To deal with this, you have a 
check that determines when the mantissa will overflow.  This is simplest with 
pure upcounters (vs. up/down counters) with an increment value that has just a 
single 1 (as opposed to incrementing by 5 or something else), since you can 
pipeline this detector.  For the simple case, you just detect that all bits of 
the count to the left or even with the 1 in the increment should be a 1.

Now, to handle mantissa overflow, you perform the addition just as normal.  
However, you must shift both the count and the increment values one to the 
right, and increment the exponent.

I'm obivously glossing over some issues, but this should give the basic 
outline of the system.  I'll leave it as an exercise to the reader to get the 
exact area counts, but I would suspect this would be almost as fast, and about 
3x larger or so, than a fixed point, non prescaled counter.

The GNU tools have been ported to NT; I think that Cygnus did the work.  In
any event, we're going to use one of the Motorola ColdFire processors for an
upcoming project, and after spending a couple of weeks futzing with the GNU
compiler, I've decided to buy the Diab Data compiler.  Runs on Unix and NT
(same price!), looks and smells like the GNU compiler, but it's documented
and supported.  And they give you some nice BOOKS (dead tree technology)
when you pays your money.

The GNU compiler documentation looks like it was created by committee.  Good
luck actually finding anything in it.

See, I'm a hardware guy whose programming background is strictly Borland
C++, and I want to get my test code up and running ASAFP.  The less time
spent dealing with cryptic make files, the better.

Now, I think that Borland (now Inprise, whatever the fark that means) could
make a killing if they ported C++ Builder to Linux.  yeah, that's the
ticket...

On the topic of "Unix apps ported to NT," uh, v5.2 of ModelSim PE uses the
same GUI as the Unix version.  There's some kind of intermediate shell
happening.  guess what? it's slooow as molasses when you're dealing with the
waveform display. YECCCCH.  for this we paid good money?

If Synopsys is willing to transfer the licenses, it would be worth many
times your $90k.  If Synopsys will not transfer the licenses, or will do
so for a steep fee (which I suspect is the case), then the unit is worth
a tiny fraction of the $90k...

Just my 2 cents (mostly for the benefit of EDA newbies reading this).

All the above are free.  Most academics public using LaTeX.

www.cygnus.com

   They port them to Windows because many engineers are unfortunately
forced to used the OS by their managers and by other software 
availability.  But, the GNU tools are very elegant and portable.
Not to mention the wide array of tools that are buildable with GNU
toolchains.  RTEMS (www.oarcorp.com) is one product buildable with GNU
tools.  There are _many_ others.

   The most unfortunate thing about Windows tools and the reason I
don't use them is that the visual environments lock you in.  They
encapsulate your project so well that it cannot be developed from
remote machines or with other tools.  Something I build in Borland
has Borland project files, Borland makefiles, etc.  I cannot easily
move it to IBM VisualAge or something else.

   On the other hand, GNU runs _everywhere_!!!  I can take code on
Solaris and easily port it to HP-UX, Linux, etc.  (``easily'' is
used loosely here -- easier than some Borland project).

   But then again, that's part of the goal.  Borland doesn't want
you to use IBM VisualAge, so they hide everything so deep that you
never get a usable Makefile.  For "helloworld.c" you get some 
obfuscated 3000 line Makefile that would never run anywhere else.
Not to mention 2 megabytes of project organization.


   Cheers,
   Jake

Has anyone out there used the Virtex embedded RAM and asynchronous ROM
and if so what success/problems have you run into?

Thanks!

while i curse word relatively frequently, i think it is sort of the right idea,
but the execution needs some help.  it's a bit quirky at times, especially with
figure placement, and crashes too much.  i wish they would stop adding features
like smart paperclips and make it more solid.  on the other hand, even with the
bugs and warts, i prefer it to latex by a lot.  it also has the feature of
being rather standard, making it easy to pass and collaborate on documents.  i
realize other programs can do this too, but this seems by far to be the most
popular.

agreed.  i worked on the unix systems with c, although it was a number of years
ago ... and i find that the delphi system (pascal + graphical programming
stuff) is far easier to use and more productive than unix.  of course, i do
small projects, usually 2-3 people.  i understand for very large products, the
unix tools for things like configuration management are better.

Subject: Low Cost latched I/O
From: "James G" <radix@NO-SPAMmediaone.net>
Date: Thu, 22 Jul 1999 22:29:53 -0700
Links: << >>  << T >>  << A >>
Hello,
I have a requirement to expand a 8051 type microprocessor bus
to a minimum of 50 latched I/O pins and up to 144  in some configurations.
When I posted this on comp.arch.embedded one suggestion was to
use the 9572XL from Xilinx.  This chip does seem to be a very good
low cost possibility.
My main requirements are low cost.  The CPLD/FPGA will interface to
an 8 bit bus with a 80 nanosecond cycle time, but if necessary the bus
can be stretched to 1,000 nanoseconds (EZ-USB).  I prefer 3.3V if it
is TTL compatible, but 5V could be used also.  The other requirement
is low power.  I have about 20 mA for the CPLD/FPGA (at
low clock frequency).
Is the 9572XL a good choice?  It comes in a 100 pin package
for about $3 in low quantity.
Thanks for any help.
James

Hello,

I am part of a research group at my university and one of the things
that we are tying to do is develop some core designs that can be used
within different xilinx fpga's (4000 and Virtex)...

Currently I am trying to design a hardware FFTand was wondering if
anyone could help me with a general (expandable) hardware design?  I
have been able to find a lot of stuff on software algorithms, but
there is very little about how to implement this in hardware... 

Thanks,

Why not put all this information on a website in .pdf or .ps format, and
include your contact information?  An isolated newsgroup post or two is
*not* going to sell your product to those who need it the most (and
probably don't have time to read the groups).
