Interesting contrast with Synplicity who, as reported
here a couple of months ago, were courteous and 
responsive in dealing with a Synplify licence
problem in my **FREE** Actel software.

Are "market leader" and "arrogant" on the
same page in _your_ thesaurus?

XCV300E and XCV1000E should be available NOW in some packages, with XCV2000E
and XCV600E to follow VERY soon.

I suggest you contact your distributor for more detailed information.

For those interested in learning more about Virtex-E, I suggest the
following reading:

Press release at: http://www.xilinx.com/prs_rls/vtxe.htm
Virtex-E FAQ at: http://www.xilinx.com/prs_rls/vtxefaq.htm
Technical Backgrounder at: http://www.xilinx.com/prs_rls/vtxebkgdr.htm
More product info at: http://www.xilinx.com/products/virtex.htm
Virtex-E datasheet: http://www.xilinx.com/partinfo/databook.htm#virtex
New appnotes at: http://www.xilinx.com/apps/virtexapp.htm

One of the application notes discusses one of the most exciting features
(and until now - the best kept secret) about the Virtex-E: The support for
622Mbps LVDS.

Also make sure you read about the SelectLink feature which offers extremely
high Virtex-to-Virtex data rates, the DLLs (of which there are now 8) which
eases system design greatly, more I/O standards, support for 200MHz ZBT RAM
and SDRAM, more memory, and lots of more...

I too had this problem since I wanted, among other things, more
documenation on the Tcl scripting in FPGA-E 3.1 since the on line help
for this is appallingly thin. The stuff I needed was on Synopsys' site
but I couldn't download without a user ID & passwd I too was told that
OEM customers have no access to to Solve-NET and should ``contact their
distributor''. The Xilinx FAE managed to get most of the stuff but I
still haven't got any info on the synthesis control Tcl commands. As a
result we made the excellent decision to buy Synplify in spite of FPGA
Express being FREE with Foundation. So far, in spite of my unusual
ability to generate bugs in all known forms of s/w, I have found only 1
in Synplify which they admitted without the usual attempt to blame the
user.

Yeah so why doesn't M2.1i support them without a special plea to your
distributor.

Links: << >>  << T >>  << A >>
Hello,
I have been teaching myself about FPGAs using Xilinx Foundation Series
1.5. I would like to get a textbook on VHDL to learn with also. Is there
any consensus as to which is better to learn, Verilog or VHSIC HDL ?
I have heard that they are both widely used, but verilog is easier.
Also, dose anyone know where I can get a used text on this subject in
the St. Pete area of Florida ?
Thanks in advance.

I can't offer Altera specific information, but LVDS is a standard and
you can get all you need to know about it either from National
Semiconductor or Texas Instruments web sites; (do a search on LVDS).

I'm curious to know who makes this.

Subject: Lucent FPGA with PCI hard core
From: "Wade D. Peterson" <peter299@maroon.tc.umn.edu>
Date: Tue, 28 Sep 1999 16:20:36 -0500
Links: << >>  << T >>  << A >>
Has anyone tried the Lucent FPGA with integrated PCI hard core?  They call it an
FPSC, and apparently, they've hard-wired a PCI core into their FPGA parts, so
you only need to develop the application part of the device (in the FPGA
section).

I found this part at: http://www.lucent.com/micro/fpga/fpsc.html

I'm considering this part for a project I'm starting, and would like to hear
from anybody who has used it.

Make a $6 investment into $6,000 in a month! INTEGRITY CAN
                                        MAKE YOU EASY MONEY!!! IT WILL!!! BUT YOU HAVE TO
                                        FOLLOW IT TO THE LETTER FOR IT TO WORK!!! A little while
                                        back, I was browsing through newsgroups, just like you are now, and
                                        came across an article similar to this that said you could make
                                        thousands of dollars within weeks with only an initial investment of
                                        $6.00! So I thought," Yeah, right, this must be a scam", but like most
                                        of us, I was curious, so I kept reading. Anyway, it said that you send
                                        $1.00 to each of the 6 names and address stated in the article. You
                                        then place your own name and address in the bottom of the list at
                                        #6, and post the article in at least 200 newsgroups. (There are
                                        thousands) No catch, that was it. So after thinking it over, and
                                        talking to a few people first, I thought about trying it. I figured what
                                        have I got to lose except 6 stamps and $6.00, right? Like most of us
                                        I was a little skeptical and a little worried about the legal aspects of it
                                        all. So I checked it out with the U.S. Post Office (1-800-725-2161)
                                        and they confirmed that it is indeed legal! Then I invested the
                                        measly $6.00. Well GUESS WHAT!!...within 7 days, I started getting
                                        money in the mail! I was shocked! I figured it would end soon, but
                                        the money just kept coming in. In my first week, I made about
                                        $25.00. By the end of the second week I had made a total of over
                                        $1,000.00! In the third week I had over $10,000.00 and it's still
                                        growing. This is now my fourth week and I have made a total of just
                                        over $42,000.00 and it's still coming in rapidly. It's certainly worth
                                        $6.00, and 6 stamps, I have spent more than that on the lottery!!
                                        Let me tell you how this works and most importantly, why it
                                        works....also, make sure you print a copy of this article NOW, so you
                                        can get the information off of it as you need it. STEP 1): Get 6
                                        separate pieces of paper and write the following on each piece of
                                        paper "PLEASE PUT ME ON YOUR MAILING LISTS". THIS HELPS
                                        TO ENSURE THAT YOU WILL BE GETTING MORE RESPONSES BY
                                        PEOPLE THAT ARE DOING THE SAME THING AS YOU. Now get 6
                                        US $1.00 bills and place ONE inside EACH of the 6 pieces of paper
                                        so the bill will not be seen through the envelope to prevent thievery.
                                        Next, place one paper in each of the 6 envelopes and seal them.
                                        You should now have 6 sealed envelopes, each with a piece of
                                        paper stating the above phrase, your name and address, and a
                                        $1.00 bill. What you are doing is creating a service by this. THIS IS
                                        ABSOLUTELY LEGAL! Mail the 6 envelopes to the following
                                        addresses:

                                        STEP 2) Now take the #1 name off the list that you see above, move
                                        the other names up (6 becomes 5, 5 becomes 4, etc...) and add
                                        YOUR NAME as number 6 on the list. STEP 3): Change anything
                                        you need to, but try to keep this article as close to the original as
                                        possible! Now, post your amended article to at least 200
                                        newsgroups. (I think there are close to 24,000 groups) All you need
                                        is 200, but remember, the more you post, the more money you
                                        make! ---DIRECTIONS-----HOW TO POST TO
                                        NEWSGROUPS------------ STEP 1): You do not need to re-type this
                                        entire letter to do your own posting. Simply put your cursor at the
                                        beginning of this letter and drag your cursor to the bottom of this
                                        letter, and select 'copy' from the 'edit' menu. This will copy the entire
                                        letter into the computers memory. STEP 2): Open a new(or blank)
                                        'WordPad' or 'Notepad' file and place your cursor at the top of the
                                        blank page. From the 'edit' menu select 'paste'. This will paste a
                                        copy of the letter into your word processor so that you can add your
                                        name to the list. STEP 3): Save your new notepad file as a .txt file. If
                                        you want to do your postings in different sittings, you'll always have
                                        this file to go back to. STEP 4): Use Netscape or Internet explorer
                                        and try searching for various newsgroups (on-line forums, message
                                        boards, chat sites, discussions). STEP 5): Visit these message
                                        boards and post this article as a new message by highlighting the
                                        text of this letter and selecting paste from the edit menu. Fill in the
                                        Subject, this will be the header that everyone sees as they scroll
                                        through the list of postings in a particular group, click the post
                                        message button. You're done with your first one!

                                        me, now those 25 each make 200 MINIMUM posts with my name at

                                        Now, those 125 persons turn around and post the MINIMUM 200 with

                                        AMAZING! When your name is no longer on the list, you just take

In http://www.sussex.ac.uk/~tapu9/list_publ.html have a look in
the paper: "A VHDL implementation of an on-board ACF application
targeting FPGAs". In the second page of the long abstract
(mapld99.pdf) there is a table showing a performance comparison
between an FPGA and a microcontroller. For this application the
FPGA implementation is faster than the microcontroller one, but
for other cases it will depend on the application.

For one thing, 'performance' is a broad term.  It can refer to: speed, density,
temperature range, radiation hardening, power consumption, time-to-market, cost
and a host of other issues.

In terms of part speeds, they are poor performers when compared to ASIC or GaAs
parts.  They are very good performers when compared to discrete logic parts.

In terms of time-to-market and development costs, they are very good performers.

Poor performers relative to what?  For many regular tasks (ones that are
repeated for many samples) as you usually find in DSP applications, you can
see performance gains over a CPU of anywhere from 10x to 1000x depending on
the application and the implementation.  FPGAs allow you to obtain low level
parallelism (doing many basic operations at once) that is not possible with
a microprocessor.  For example, if you need to sum a bunch of data points,
the processor has to do one addition at a time, where the FPGA can do them
all at once using an adder tree.

I routinely do DSP designs in FPGAs with data sample rates over 100 MS/sec.
Applications include radar and wireless communications.  Operations done in
the FPGA include demodulation, filtering, radar signal processing etc.  Even
the fastest CPUs would only be capable of doing one or two instructions per
sample, which is totally inadequate for the complex functions above.

If you're not afraid to build something, you can gather up the ISP
documents for all the parts you intend to program, then design a
circuit which meets all the contstraints and build it yourself.
That's probably the least costly way to manage this problem.

Generate an .inc file (File / Generate Default inc file) for the GDF and use it

You'll have to check how large the configuration is for your FPGA. If less
than 1 megabit, I'd recommend the AT17LV010. It's a small PLCC which is easy
to use with a socket. I can't recall the name of the document, but Atmel has
application notes for making the correct connections between the FPGA and
configuration device.

Pardon me if this is an obvious question.  I don't need an explicit reset
pin since all flip-flops are reset on initialization anyway.  How do I get
foundation express to use GSR without having to waste a pin for it?  If I
remove reset from the top level port list, it complains.  If I set it to
zero, it complains.  If I instiantiate the STARTUP module, but don't drive
reset it complains.  If I remove the reset net all together, it complains
and flip flops may not be reset to the correct level (if negative ones are
inferred).  Do you always have to waste a pin for a redundant reset line?

module toplevel(clk,reset,in,out);
input clk, reset, in;
output out;
reg out;

Links: << >>  << T >>  << A >>
Depends.  If your doing FPGAs, then I recommend VHDL over Verilog.  The
reason for this, is although Verilog is easier to learn, it is not well
suited for the occasional low level stuff that comes up in FPGAs.  With
VHDL, you can at least take a stab at specifying placement in the code and
can get the control over implementation when needed.

If youre doing ASICs in the US, then you'll probably want to use verilog, as
that seems to be the standard.  In Europe, ASIC work is more VHDL.
